Abstract A total of 100 samples of Oreochromis niloticus from the lower New Calabar River were examined to determine

their levels of nematode parasitemia using standard parasitological techniques An overall prevalence of (59) was recorded

comprising (5) ectoparasites and (54) endoparasites Sex related parasitemia showed that males harboured more parasites

(43) compared to (16) recovered in the females (Pgt005) Parasite specificity revealed three nematodes Capillaria spp

(21) Eustrongylide spp (15) and Goezia sigalasi (Ascarididae) (18) and Lernaeocera branchialis (5) a crustacean

were recovered from the samples However the study revealed a progressive increase in parasitemia as age of the fish host

increased (Plt005) The high parasitemia observed in this study was associated with the tidal effects of the water system which

influences the organic load of the benthos directly and fish nutrition indirectly

Key word Parasitemia ectopaarasites endoparasites sex related parasitemia tidal effect organic load and benthos

1 INTRODUCTION

Parasites are always present in any community (plants

and animals) and usually infect hosts species that

dominate the higher trophic levels in any food chain

(Maclinnis 1976 Edem et al 2008) Fish which

naturally occupies the top of the predator-prey

pyramid in freshwater and marine environments is

most affected by parasites due to some predisposing

factors such as physiologic specificity (age genotype

sex etc) nutritional specificity and ecologic

characteristics (Ravichandran and Ajithkumar 2008

Adam et al 2009)

11 Effect of parasites on fish species

Parasitism of fish and fishery is a cause of worry to

fish culturists and artisanal fishermen in the in-land

and coastal waters of Nigeria (Ukoli 1988 Umuoeren

et al 1988 Onwuliri and Mgbemena 1998

Awharioma and Okaka 1999 and Edema and Okaka

2008) This concern is attributed to parasite induced

economic losses and negative health implications

manifesting in forms of poor fish productivity poor

marketability of caught fish reduction in protein

availability and reduction in job opportunities due to

lack of motivation to invest in aquacultural activities

by potential investors (Meyer and Hoffman 1976

Van Dan Brook 1979 and Awharitoma and Ehigiafor

2012)

Tillapia a cherished cichlid of variable species

common in Nigeria is greatly infected by parasites

(Ukoli 1988 Umuoeren et al 1988 Onwuliri and

Mgbemena 1998 Awharioma and Okaka 1999

Edema and Okaka 2008 and Awharitoma and

Ehigiafor 2012) Studies have indicated that

Tillapiarsquos adaptability to various aquacultural systems

is due to its high fecundity hardiness tolerance to

poor water quality salinity temperature and pH

(Chervinski 1973 Abbas et al 2009 Awharitoma

and Ehigiafor 2012) characteristics which inevitably

predisposes it to parasitism In the Niger Delta where

more than 60 of the populace depend on

aquacultural activities for their livelihood it is apt to

determine the current status of nematode parasitic

fuana of O niloticus from the lower New Calabar

River

22 MATERIALS AND METHODS

21 Study Area

The study was carried out on the lower New Calabar

River situated at Choba in ObioAkpor LGA Rivers

State of Nigeria The area lies between latitude 5˚ 54

295 N and longitudes 6˚ 53 889 and 7˚E

experiences an average rainfall of 2500cm3 and

temperature range of between 28˚C-30˚C annually

which supports the rainforest type of vegetation The

area is sub-urban in structure with about 40 of the

populace predominantly rural artisanal fishermen and

subsistent farmers However the life style of the

indigenes is greatly influenced by the presence of the

University of Port Harcourt and several industries

22 Collection of samples

Hundred (100) freshly caught Oniloticus were

selected using the stratified random sampling

technique (the fourth fish out of every four counts

was selected) between the months of August to

October 2012 Each fish was put in a properly

labelled polyethene bag which was secured in a vat

and transported to the laboratory for examination

23 Physical examination

Fish samples were isolated from vat weighed and

total lengths determined Skin examination of the

samples were carried out with a x10 hand lens to

detect any attached parasite afterwards the skins of

the fish samples were scraped and the scrapings used

to prepare thin smears for microscopic examination

Gill examination was carried out by the use of x10

hand lens in situ and on detached gills Further

examinations of detached gills were conducted with a

stereoscopic microscope

The abdominal cavities of the samples were

opened and the mesenteries examined for migratory

juveniles of nematodes Gastrointestinal tract of the

samples were excised and contents extracted into a

5ml beaker containing normal saline and later stored

in properly labelled sterile vials containing 4

formalin and processed using the formal-ether

concentration method for further microscopic

examination

24 Microscopy

Thin and thick smears of skin scrapings were prepared

and observed under x10 and x40 objectives for

presence of parasites Gastro-intestinal endothelial

scrapings were used to prepare wet smears (stained

with Lugolrsquos iodine) The intestinal contents of the

samples were also examined using the formal-ether

concentration technique and microscopically

examined at x10 and x40 objectives Identification of

parasites was done using Zdenek Locky (1977) and

Cheng (1986) guides

25 Statistical analysis

Measures of central tendency and chi square were

used to analyse the results

3 RESULTS

Table 1 shows the prevalence of Oniloticus from the

lower New Calabar river A total of 100 fish samples

were examined showing an infection of 59(59) out

of which 5(50) and 54(540) were for

ectoparasites and endoparsites respectively Age

related prevalence increased as age increased

Sex related prevalence of parasites in the sampled

fishes indicated an overall prevalence of 43(43) and

16(16) for male and female respectively The data

further showed higher prevalence of endoparasites

(43) to ectoparasites (16) (Figure 1)

The study revealed two phyla of parasites

Nematode and the Arthropoda in Oniloticus from the

study area Amongst the nematodes were the

Capillaria spp Eustrongylide spp and Ascarididae

(Goezia sigalasi) while Lernaeocera branchialis was

the only crustacean discovered (Figure 1)

4 DISCUSSION

The overall prevalence (590) of parasites in

Oniloticus from the lower New Calabar River was

rather high for a tidal river but within the range for

inland waters as stated by Onwuliri and Mgbemena

(1998) Umuoeren et al (1988) and Awharioma and

Okaka (1999) However the study showed variability

in the density of parasites within the groups with the

gt225cm length range harbouring the highest

prevalence (90) This pattern of parasitism was

consistent with (Paperna 1996 Mbahinzireki 1980

Wanderson et al 2012 Ashade et al 2013) who

observed a gradual consistent increase in parasitemia

as fish aged However this trend was not consistent

with the ectoparasites which drastically declined as

fish samples aged A trend the researchers attribute to

possible accidental dislodgement of some

ectoparasites due to out of water fish resistance by the

fish samples The higher parasitemia (43) in female

samples than the male counterparts (16) an

observation that contradicts the report by Olurin et al

(2012) and agrees with that of Thomas (1964) is an

issue that has enjoyed flux in opinion by researchers

(Price and Clancy1983 and Olorin and Somorin

2006) However this physiological preference was

attributed to host specific factors On specific parasitamia the endoparastes

consisting the nematodes had a higher density on

individual sample basis than the crustaceans

(ectoparasites) Also there was a progressive

increase in nematode parasitemia as fish samples aged

(Mbahinzireki 1980 Paperna 1996 and Awharitoma

and Ehigiafor 2012) This result was consistent with

Paperna (1996) who attributed the age related

prevalence to repeated infections and accumulation of

parasite load with increased age Other factors which

may have influenced the high prevalence of parasitic

nematodes in this study include the tidal

characteristics of the river coupled with the rich

organic constitution of the benthos which harbours

rich population of annalides that aid in the

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 263-267 2013

265

transmission of nematode parasites as fish ingest them

(Kennedy 1975 Cheng 1986 Ukoli 1988 Edema

and Okaka 2008) The absence of monogenean

parasites in the examined samples was in line with

some previous studies in inland waters of Africa by

Paperna and Thurston (1968) The absence of

monogenean in the study area could also be an

indication of the quality of the environment or the

immune status of the samples (Wanderson et al

2012 Ashade et al 2013)

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

four groups Blossom-end rot in BSS282 Tima and TO4 were less than others

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

277

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract A total of 100 samples of Oreochromis niloticus from the lower New Calabar River were examined to determine

their levels of nematode parasitemia using standard parasitological techniques An overall prevalence of (59) was recorded

comprising (5) ectoparasites and (54) endoparasites Sex related parasitemia showed that males harboured more parasites

(43) compared to (16) recovered in the females (Pgt005) Parasite specificity revealed three nematodes Capillaria spp

(21) Eustrongylide spp (15) and Goezia sigalasi (Ascarididae) (18) and Lernaeocera branchialis (5) a crustacean

were recovered from the samples However the study revealed a progressive increase in parasitemia as age of the fish host

increased (Plt005) The high parasitemia observed in this study was associated with the tidal effects of the water system which

influences the organic load of the benthos directly and fish nutrition indirectly

Key word Parasitemia ectopaarasites endoparasites sex related parasitemia tidal effect organic load and benthos

1 INTRODUCTION

Parasites are always present in any community (plants

and animals) and usually infect hosts species that

dominate the higher trophic levels in any food chain

(Maclinnis 1976 Edem et al 2008) Fish which

naturally occupies the top of the predator-prey

pyramid in freshwater and marine environments is

most affected by parasites due to some predisposing

factors such as physiologic specificity (age genotype

sex etc) nutritional specificity and ecologic

characteristics (Ravichandran and Ajithkumar 2008

Adam et al 2009)

11 Effect of parasites on fish species

Parasitism of fish and fishery is a cause of worry to

fish culturists and artisanal fishermen in the in-land

and coastal waters of Nigeria (Ukoli 1988 Umuoeren

et al 1988 Onwuliri and Mgbemena 1998

Awharioma and Okaka 1999 and Edema and Okaka

2008) This concern is attributed to parasite induced

economic losses and negative health implications

manifesting in forms of poor fish productivity poor

marketability of caught fish reduction in protein

availability and reduction in job opportunities due to

lack of motivation to invest in aquacultural activities

by potential investors (Meyer and Hoffman 1976

Van Dan Brook 1979 and Awharitoma and Ehigiafor

2012)

Tillapia a cherished cichlid of variable species

common in Nigeria is greatly infected by parasites

(Ukoli 1988 Umuoeren et al 1988 Onwuliri and

Mgbemena 1998 Awharioma and Okaka 1999

Edema and Okaka 2008 and Awharitoma and

Ehigiafor 2012) Studies have indicated that

Tillapiarsquos adaptability to various aquacultural systems

is due to its high fecundity hardiness tolerance to

poor water quality salinity temperature and pH

(Chervinski 1973 Abbas et al 2009 Awharitoma

and Ehigiafor 2012) characteristics which inevitably

predisposes it to parasitism In the Niger Delta where

more than 60 of the populace depend on

aquacultural activities for their livelihood it is apt to

determine the current status of nematode parasitic

fuana of O niloticus from the lower New Calabar

River

22 MATERIALS AND METHODS

21 Study Area

The study was carried out on the lower New Calabar

River situated at Choba in ObioAkpor LGA Rivers

State of Nigeria The area lies between latitude 5˚ 54

295 N and longitudes 6˚ 53 889 and 7˚E

experiences an average rainfall of 2500cm3 and

temperature range of between 28˚C-30˚C annually

which supports the rainforest type of vegetation The

area is sub-urban in structure with about 40 of the

populace predominantly rural artisanal fishermen and

subsistent farmers However the life style of the

indigenes is greatly influenced by the presence of the

University of Port Harcourt and several industries

22 Collection of samples

Hundred (100) freshly caught Oniloticus were

selected using the stratified random sampling

technique (the fourth fish out of every four counts

was selected) between the months of August to

October 2012 Each fish was put in a properly

labelled polyethene bag which was secured in a vat

and transported to the laboratory for examination

23 Physical examination

Fish samples were isolated from vat weighed and

total lengths determined Skin examination of the

samples were carried out with a x10 hand lens to

detect any attached parasite afterwards the skins of

the fish samples were scraped and the scrapings used

to prepare thin smears for microscopic examination

Gill examination was carried out by the use of x10

hand lens in situ and on detached gills Further

examinations of detached gills were conducted with a

stereoscopic microscope

The abdominal cavities of the samples were

opened and the mesenteries examined for migratory

juveniles of nematodes Gastrointestinal tract of the

samples were excised and contents extracted into a

5ml beaker containing normal saline and later stored

in properly labelled sterile vials containing 4

formalin and processed using the formal-ether

concentration method for further microscopic

examination

24 Microscopy

Thin and thick smears of skin scrapings were prepared

and observed under x10 and x40 objectives for

presence of parasites Gastro-intestinal endothelial

scrapings were used to prepare wet smears (stained

with Lugolrsquos iodine) The intestinal contents of the

samples were also examined using the formal-ether

concentration technique and microscopically

examined at x10 and x40 objectives Identification of

parasites was done using Zdenek Locky (1977) and

Cheng (1986) guides

25 Statistical analysis

Measures of central tendency and chi square were

used to analyse the results

3 RESULTS

Table 1 shows the prevalence of Oniloticus from the

lower New Calabar river A total of 100 fish samples

were examined showing an infection of 59(59) out

of which 5(50) and 54(540) were for

ectoparasites and endoparsites respectively Age

related prevalence increased as age increased

Sex related prevalence of parasites in the sampled

fishes indicated an overall prevalence of 43(43) and

16(16) for male and female respectively The data

further showed higher prevalence of endoparasites

(43) to ectoparasites (16) (Figure 1)

The study revealed two phyla of parasites

Nematode and the Arthropoda in Oniloticus from the

study area Amongst the nematodes were the

Capillaria spp Eustrongylide spp and Ascarididae

(Goezia sigalasi) while Lernaeocera branchialis was

the only crustacean discovered (Figure 1)

4 DISCUSSION

The overall prevalence (590) of parasites in

Oniloticus from the lower New Calabar River was

rather high for a tidal river but within the range for

inland waters as stated by Onwuliri and Mgbemena

(1998) Umuoeren et al (1988) and Awharioma and

Okaka (1999) However the study showed variability

in the density of parasites within the groups with the

gt225cm length range harbouring the highest

prevalence (90) This pattern of parasitism was

consistent with (Paperna 1996 Mbahinzireki 1980

Wanderson et al 2012 Ashade et al 2013) who

observed a gradual consistent increase in parasitemia

as fish aged However this trend was not consistent

with the ectoparasites which drastically declined as

fish samples aged A trend the researchers attribute to

possible accidental dislodgement of some

ectoparasites due to out of water fish resistance by the

fish samples The higher parasitemia (43) in female

samples than the male counterparts (16) an

observation that contradicts the report by Olurin et al

(2012) and agrees with that of Thomas (1964) is an

issue that has enjoyed flux in opinion by researchers

(Price and Clancy1983 and Olorin and Somorin

2006) However this physiological preference was

attributed to host specific factors On specific parasitamia the endoparastes

consisting the nematodes had a higher density on

individual sample basis than the crustaceans

(ectoparasites) Also there was a progressive

increase in nematode parasitemia as fish samples aged

(Mbahinzireki 1980 Paperna 1996 and Awharitoma

and Ehigiafor 2012) This result was consistent with

Paperna (1996) who attributed the age related

prevalence to repeated infections and accumulation of

parasite load with increased age Other factors which

may have influenced the high prevalence of parasitic

nematodes in this study include the tidal

characteristics of the river coupled with the rich

organic constitution of the benthos which harbours

rich population of annalides that aid in the

265

transmission of nematode parasites as fish ingest them

(Kennedy 1975 Cheng 1986 Ukoli 1988 Edema

and Okaka 2008) The absence of monogenean

parasites in the examined samples was in line with

some previous studies in inland waters of Africa by

Paperna and Thurston (1968) The absence of

monogenean in the study area could also be an

indication of the quality of the environment or the

immune status of the samples (Wanderson et al

2012 Ashade et al 2013)

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract A total of 100 samples of Oreochromis niloticus from the lower New Calabar River were examined to determine

their levels of nematode parasitemia using standard parasitological techniques An overall prevalence of (59) was recorded

comprising (5) ectoparasites and (54) endoparasites Sex related parasitemia showed that males harboured more parasites

(43) compared to (16) recovered in the females (Pgt005) Parasite specificity revealed three nematodes Capillaria spp

(21) Eustrongylide spp (15) and Goezia sigalasi (Ascarididae) (18) and Lernaeocera branchialis (5) a crustacean

were recovered from the samples However the study revealed a progressive increase in parasitemia as age of the fish host

increased (Plt005) The high parasitemia observed in this study was associated with the tidal effects of the water system which

influences the organic load of the benthos directly and fish nutrition indirectly

Key word Parasitemia ectopaarasites endoparasites sex related parasitemia tidal effect organic load and benthos

1 INTRODUCTION

Parasites are always present in any community (plants

and animals) and usually infect hosts species that

dominate the higher trophic levels in any food chain

(Maclinnis 1976 Edem et al 2008) Fish which

naturally occupies the top of the predator-prey

pyramid in freshwater and marine environments is

most affected by parasites due to some predisposing

factors such as physiologic specificity (age genotype

sex etc) nutritional specificity and ecologic

characteristics (Ravichandran and Ajithkumar 2008

Adam et al 2009)

11 Effect of parasites on fish species

Parasitism of fish and fishery is a cause of worry to

fish culturists and artisanal fishermen in the in-land

and coastal waters of Nigeria (Ukoli 1988 Umuoeren

et al 1988 Onwuliri and Mgbemena 1998

Awharioma and Okaka 1999 and Edema and Okaka

2008) This concern is attributed to parasite induced

economic losses and negative health implications

manifesting in forms of poor fish productivity poor

marketability of caught fish reduction in protein

availability and reduction in job opportunities due to

lack of motivation to invest in aquacultural activities

by potential investors (Meyer and Hoffman 1976

Van Dan Brook 1979 and Awharitoma and Ehigiafor

2012)

Tillapia a cherished cichlid of variable species

common in Nigeria is greatly infected by parasites

(Ukoli 1988 Umuoeren et al 1988 Onwuliri and

Mgbemena 1998 Awharioma and Okaka 1999

Edema and Okaka 2008 and Awharitoma and

Ehigiafor 2012) Studies have indicated that

Tillapiarsquos adaptability to various aquacultural systems

is due to its high fecundity hardiness tolerance to

poor water quality salinity temperature and pH

(Chervinski 1973 Abbas et al 2009 Awharitoma

and Ehigiafor 2012) characteristics which inevitably

predisposes it to parasitism In the Niger Delta where

more than 60 of the populace depend on

aquacultural activities for their livelihood it is apt to

determine the current status of nematode parasitic

fuana of O niloticus from the lower New Calabar

River

22 MATERIALS AND METHODS

21 Study Area

The study was carried out on the lower New Calabar

River situated at Choba in ObioAkpor LGA Rivers

State of Nigeria The area lies between latitude 5˚ 54

295 N and longitudes 6˚ 53 889 and 7˚E

experiences an average rainfall of 2500cm3 and

temperature range of between 28˚C-30˚C annually

which supports the rainforest type of vegetation The

area is sub-urban in structure with about 40 of the

populace predominantly rural artisanal fishermen and

subsistent farmers However the life style of the

indigenes is greatly influenced by the presence of the

University of Port Harcourt and several industries

22 Collection of samples

Hundred (100) freshly caught Oniloticus were

selected using the stratified random sampling

technique (the fourth fish out of every four counts

was selected) between the months of August to

October 2012 Each fish was put in a properly

labelled polyethene bag which was secured in a vat

and transported to the laboratory for examination

23 Physical examination

Fish samples were isolated from vat weighed and

total lengths determined Skin examination of the

samples were carried out with a x10 hand lens to

detect any attached parasite afterwards the skins of

the fish samples were scraped and the scrapings used

to prepare thin smears for microscopic examination

Gill examination was carried out by the use of x10

hand lens in situ and on detached gills Further

examinations of detached gills were conducted with a

stereoscopic microscope

The abdominal cavities of the samples were

opened and the mesenteries examined for migratory

juveniles of nematodes Gastrointestinal tract of the

samples were excised and contents extracted into a

5ml beaker containing normal saline and later stored

in properly labelled sterile vials containing 4

formalin and processed using the formal-ether

concentration method for further microscopic

examination

24 Microscopy

Thin and thick smears of skin scrapings were prepared

and observed under x10 and x40 objectives for

presence of parasites Gastro-intestinal endothelial

scrapings were used to prepare wet smears (stained

with Lugolrsquos iodine) The intestinal contents of the

samples were also examined using the formal-ether

concentration technique and microscopically

examined at x10 and x40 objectives Identification of

parasites was done using Zdenek Locky (1977) and

Cheng (1986) guides

25 Statistical analysis

Measures of central tendency and chi square were

used to analyse the results

3 RESULTS

Table 1 shows the prevalence of Oniloticus from the

lower New Calabar river A total of 100 fish samples

were examined showing an infection of 59(59) out

of which 5(50) and 54(540) were for

ectoparasites and endoparsites respectively Age

related prevalence increased as age increased

Sex related prevalence of parasites in the sampled

fishes indicated an overall prevalence of 43(43) and

16(16) for male and female respectively The data

further showed higher prevalence of endoparasites

(43) to ectoparasites (16) (Figure 1)

The study revealed two phyla of parasites

Nematode and the Arthropoda in Oniloticus from the

study area Amongst the nematodes were the

Capillaria spp Eustrongylide spp and Ascarididae

(Goezia sigalasi) while Lernaeocera branchialis was

the only crustacean discovered (Figure 1)

4 DISCUSSION

The overall prevalence (590) of parasites in

Oniloticus from the lower New Calabar River was

rather high for a tidal river but within the range for

inland waters as stated by Onwuliri and Mgbemena

(1998) Umuoeren et al (1988) and Awharioma and

Okaka (1999) However the study showed variability

in the density of parasites within the groups with the

gt225cm length range harbouring the highest

prevalence (90) This pattern of parasitism was

consistent with (Paperna 1996 Mbahinzireki 1980

Wanderson et al 2012 Ashade et al 2013) who

observed a gradual consistent increase in parasitemia

as fish aged However this trend was not consistent

with the ectoparasites which drastically declined as

fish samples aged A trend the researchers attribute to

possible accidental dislodgement of some

ectoparasites due to out of water fish resistance by the

fish samples The higher parasitemia (43) in female

samples than the male counterparts (16) an

observation that contradicts the report by Olurin et al

(2012) and agrees with that of Thomas (1964) is an

issue that has enjoyed flux in opinion by researchers

(Price and Clancy1983 and Olorin and Somorin

2006) However this physiological preference was

attributed to host specific factors On specific parasitamia the endoparastes

consisting the nematodes had a higher density on

individual sample basis than the crustaceans

(ectoparasites) Also there was a progressive

increase in nematode parasitemia as fish samples aged

(Mbahinzireki 1980 Paperna 1996 and Awharitoma

and Ehigiafor 2012) This result was consistent with

Paperna (1996) who attributed the age related

prevalence to repeated infections and accumulation of

parasite load with increased age Other factors which

may have influenced the high prevalence of parasitic

nematodes in this study include the tidal

characteristics of the river coupled with the rich

organic constitution of the benthos which harbours

rich population of annalides that aid in the

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 263-267 2013

265

transmission of nematode parasites as fish ingest them

(Kennedy 1975 Cheng 1986 Ukoli 1988 Edema

and Okaka 2008) The absence of monogenean

parasites in the examined samples was in line with

some previous studies in inland waters of Africa by

Paperna and Thurston (1968) The absence of

monogenean in the study area could also be an

indication of the quality of the environment or the

immune status of the samples (Wanderson et al

2012 Ashade et al 2013)

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

four groups Blossom-end rot in BSS282 Tima and TO4 were less than others

Key words Genetic diversity tomato Multivariate analysis

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

277

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

22 Collection of samples

Hundred (100) freshly caught Oniloticus were

selected using the stratified random sampling

technique (the fourth fish out of every four counts

was selected) between the months of August to

October 2012 Each fish was put in a properly

labelled polyethene bag which was secured in a vat

and transported to the laboratory for examination

23 Physical examination

Fish samples were isolated from vat weighed and

total lengths determined Skin examination of the

samples were carried out with a x10 hand lens to

detect any attached parasite afterwards the skins of

the fish samples were scraped and the scrapings used

to prepare thin smears for microscopic examination

Gill examination was carried out by the use of x10

hand lens in situ and on detached gills Further

examinations of detached gills were conducted with a

stereoscopic microscope

The abdominal cavities of the samples were

opened and the mesenteries examined for migratory

juveniles of nematodes Gastrointestinal tract of the

samples were excised and contents extracted into a

5ml beaker containing normal saline and later stored

in properly labelled sterile vials containing 4

formalin and processed using the formal-ether

concentration method for further microscopic

examination

24 Microscopy

Thin and thick smears of skin scrapings were prepared

and observed under x10 and x40 objectives for

presence of parasites Gastro-intestinal endothelial

scrapings were used to prepare wet smears (stained

with Lugolrsquos iodine) The intestinal contents of the

samples were also examined using the formal-ether

concentration technique and microscopically

examined at x10 and x40 objectives Identification of

parasites was done using Zdenek Locky (1977) and

Cheng (1986) guides

25 Statistical analysis

Measures of central tendency and chi square were

used to analyse the results

3 RESULTS

Table 1 shows the prevalence of Oniloticus from the

lower New Calabar river A total of 100 fish samples

were examined showing an infection of 59(59) out

of which 5(50) and 54(540) were for

ectoparasites and endoparsites respectively Age

related prevalence increased as age increased

Sex related prevalence of parasites in the sampled

fishes indicated an overall prevalence of 43(43) and

16(16) for male and female respectively The data

further showed higher prevalence of endoparasites

(43) to ectoparasites (16) (Figure 1)

The study revealed two phyla of parasites

Nematode and the Arthropoda in Oniloticus from the

study area Amongst the nematodes were the

Capillaria spp Eustrongylide spp and Ascarididae

(Goezia sigalasi) while Lernaeocera branchialis was

the only crustacean discovered (Figure 1)

4 DISCUSSION

The overall prevalence (590) of parasites in

Oniloticus from the lower New Calabar River was

rather high for a tidal river but within the range for

inland waters as stated by Onwuliri and Mgbemena

(1998) Umuoeren et al (1988) and Awharioma and

Okaka (1999) However the study showed variability

in the density of parasites within the groups with the

gt225cm length range harbouring the highest

prevalence (90) This pattern of parasitism was

consistent with (Paperna 1996 Mbahinzireki 1980

Wanderson et al 2012 Ashade et al 2013) who

observed a gradual consistent increase in parasitemia

as fish aged However this trend was not consistent

with the ectoparasites which drastically declined as

fish samples aged A trend the researchers attribute to

possible accidental dislodgement of some

ectoparasites due to out of water fish resistance by the

fish samples The higher parasitemia (43) in female

samples than the male counterparts (16) an

observation that contradicts the report by Olurin et al

(2012) and agrees with that of Thomas (1964) is an

issue that has enjoyed flux in opinion by researchers

(Price and Clancy1983 and Olorin and Somorin

2006) However this physiological preference was

attributed to host specific factors On specific parasitamia the endoparastes

consisting the nematodes had a higher density on

individual sample basis than the crustaceans

(ectoparasites) Also there was a progressive

increase in nematode parasitemia as fish samples aged

(Mbahinzireki 1980 Paperna 1996 and Awharitoma

and Ehigiafor 2012) This result was consistent with

Paperna (1996) who attributed the age related

prevalence to repeated infections and accumulation of

parasite load with increased age Other factors which

may have influenced the high prevalence of parasitic

nematodes in this study include the tidal

characteristics of the river coupled with the rich

organic constitution of the benthos which harbours

rich population of annalides that aid in the

transmission of nematode parasites as fish ingest them

(Kennedy 1975 Cheng 1986 Ukoli 1988 Edema

and Okaka 2008) The absence of monogenean

parasites in the examined samples was in line with

some previous studies in inland waters of Africa by

Paperna and Thurston (1968) The absence of

monogenean in the study area could also be an

indication of the quality of the environment or the

immune status of the samples (Wanderson et al

2012 Ashade et al 2013)

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

The solutions of equation (2) gives the values of

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

parasites in the examined samples was in line with

some previous studies in inland waters of Africa by

Paperna and Thurston (1968) The absence of

monogenean in the study area could also be an

indication of the quality of the environment or the

immune status of the samples (Wanderson et al

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

four groups Blossom-end rot in BSS282 Tima and TO4 were less than others

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

four groups Blossom-end rot in BSS282 Tima and TO4 were less than others

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Venule blood samples were randomly collected from eighty pregnant women receiving ante natal care in the

University of Port Harcourt Primary Health Care Centre after obtaining ethical clearance These blood samples were put in

EDTA properly designated bottles and taken to the Parasitology Laboratory Department of Animal and Environmental

Biology for examination The standard thick and thin smears were used to examine the blood specimens Overall prevalence

showed that 725 of the pregnant women were infected with malaria Specific Plasmodium prevalence amongst the infected

showed that 635 were infected with P falciparum 189 for P vivax 155 for Pmalariae and 17 for Povale There

was no statistically significant (Pgt005) increase in the prevalence of Plasmodium species between the primigravidea (586)

and the multigravidae (413) The disparity in parasitemia was attributed to pregnancy induced delayed antibody expression

in the primigravidae The study emphasized the significance of health education in malaria control especially during

pregnancy

Key words Specific Plasmodium prevalence primigravidea multigravidae delayed antibody expression

1 INTRODUCTION

Malaria control is major challenges in Africa where

over 588 million people in the 45 endemic countries

are at risk especially children and pregnant women

(Newman et al 2003 WHO 2008 Agomo et al

2009) Statistics indicate that Nigeria alone accounts

for 45 prevalence in the Africa continent a fact not

far-fetched when the population of the country is

considered (Federal Ministry of Health (FMH) 2000

National Census 2006 Adefioye et al 2007)

Reports by FMH (2000) and Agomo et al (2009)

stated that the prevalence of malaria has shown

significant reduction in other African countries except

Nigeria a position which presents a gloomy future for

malaria eradication in Nigeria amidst the huge efforts

by the government and non-governmental agencies at

combating the menace

11 Malaria in Pregnancy A Public Health

Challenge in Sub-Saharan Africa

Okpere et al (2010) stated that pregnancy results in

increased incidence and severity of malaria which has

been implicated for complications in pregnancy In

sub Saharan Africa anaemia spontaneous abortion

prematurity and stillbirths are common symptoms of

the disease In Nigeria the disease is a major public

health challenge as malaria alone accounts for 11

maternal deaths annually (WHO 2010 Amoran et al

2012) However no matter how alarming these

statistics may sound some researchers still express

doubts about their accuracy especially on the true

status of malaria parasitemia in pregnancy in Nigeria

(Eze et al 2010) This discrepancy is not unconnected

with the poor documentation of cases of malaria in

pregnancy in health establishments and the attitude of

pregnant women in the rural areas patronizing

unorthodox health care services (Eze et al 2010)

Experts in epidemiology have identified poor

surveillance and poor intervention coverage by the

government as a contributory factor to the increase in

cases of malaria in Nigeria (Desai et al 2007 Enato

et al 2007 Okpere et al 2010 Olurunfemi 2012)

12 Factors that Predispose Pregnant Women to

increased Malaria Parasitemia

Several studies have established radical physiological

and behavioural changes such as increased volume of

exhaled air release of increased levels of cortisol and

volatile compounds due to increase body temperature

that predispose pregnant women to increase in

mosquito bites (Lindsay et al 2000 Martνnez-

Nzeako et al

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Prevalence of Malaria in Pregnant Women Attending Ante Natal Care at University of Port Harcourt Primary Health

Care Centre Aluu Port Harcourt Rivers State Nigeria

269

Espinosa et al 2000 Bouyou-Akotet et al 2005

Rogerson and Boeu 2007 and Enato et al 2007 and

2009 WHO 2010) In endemic countries like Nigeria

20 of malaria parasitemia in pregnancy are

asymptomatic with susceptibility to parasitemia

common in primgravidae (Desai et al 2007

Rogerson et al 2007 Amoran 2012) Agomo et al

(2009) stated that amongst the factors identified to

increase the risk of malaria infection include young

maternal age (lt20years) and gravidity

(primigravidae) This problem is further aggravated by

the paucity in Primary health facilities and the

preference of pregnant women for unorthodox health

care providers especially in the rural areas (Nduka et

al 2011 Amoran 2012 Molina and Gonzalez

2012) This study is aimed at determining the malaria

parasitaemia in primigravidae and multigravidae

pregnant women on ante-natal care programme at the

University of Port Harcourt Primary Health Care

Centre Aluu Rivers State Nigeria

2 MATERIALS AND METHODS

21 Study Area

The study was carried out at the University of Port

Harcourt Primary Health Centre situated at Aluu in

Ikwere LGA Rivers State Nigeria The area lies

between latitude 5˚ 54 295 N and longitudes 6˚ 53

889 and 7˚E experiences an average rainfall of

2500cm3 and temperature range of between 28˚C-

30˚C annually which supports the rainforest type of

vegetation The area is sub-urban in structure with

about 40 of the populace being predominantly rural

artisanal fishermen and subsistent farmers However

the life style of the indigenes is greatly influenced by

the presence of the University of Port Harcourt and

several industries

22 Collection of Blood Samples to evaluate

Plasmodium spp Parasitemia

Venule blood samples were randomly collected from

eighty pregnant women receiving ante natal care in

the University of Port Harcourt Primary Health Care

Centre after obtaining informed consent and ethical

clearance from the Chief Medical Officer of the

centre These blood samples (20microl of blood) were

collected in properly designated EDTA bottles and

taken to the Parasitology Laboratory Department of

Animal and Environmental Biology University of

Port Harcourt for examination within 24hours

The standard thick and thin smears on a single slide

were used to examine the blood specimens

(Cheesbrough 2005) Data were analysed with Excel

ANOVA

3 RESULTS AND DISCUSSIONS

In the study the overall prevalence showed that 58

(725) of the sampled pregnant women were

infected with malaria Specific prevalence of

Plasmodium amongst the infected showed that P

falciparum was the dominant species in the sampled

group (Table 1) There was no statistically significant

(Pgt005) difference in the prevalence of specific

Plasmodium species between the primigravidea

(850) and the multigravidae (150) However the

primigravidae expressed more specific parasitemia

than the multigravidae in the sampled group

Suppressed immunity due to pregnancy

The study show cases the level of malaria parasitemia

in a select group of pregnant women attending ante

natal care in a primary health centre in the Niger

Delta In the study there was high prevalence of

malaria parasitemia amongst the examined set (Table

1) which was in line with several studies including

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

Chimere et al 2009 Enato et al 2009 WHO 2010

Olunfemi et al 2012) where results indicated heavy

and multiple species malaria parasitemia in

pregnancy Naturally indigenes of the study area

readily acquire immunity due to repeated exposure to

Plasmodium spp of parasites (Bassey et al 2007

Rogerson et al 2007 Amoran et al 2012) which

declines as pregnancy set-in (Amoran 2012 Molina

and Gonzalez 2012) This decline in immunity could

be attributed to physiological and behavioural changes

that result to increase in the levels of cortisol and

volatile compounds that make pregnant women more

attractive to infected female anopheles mosquito

(Lindsay et al 2000 Martνnez-Espinosa et al 2000

Bouyou-Akotet et al 2005 Rogerson and Boeu 2007

and Enato et al 2009 WHO 2010 Molina and

Gonzalez 2012) Another factor that may have

impacted on the disparity in malaria parasitemia is the

patronage of alternative ante natal health care

providers such as herbalists and traditional midwifes

scattered around the rural areas of Nigeria by pregnant

women

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

4 CONCLUSION

The study thereby states that the disparity in

Plasmodium spp parasitemia between the

multigravidae and primigravidae could be attributed to

acquired immune-efficiency of the multigravidae to

malaria (Martνnez-Espinosa et al 2000 Bouyou-

Akotet et al 2005 Opkere et al 2010) as parity

advances Depressed immunity due to delayed

antibody expression andor lack of awareness on the

necessary preventive measures in pregnancy could

also be responsible for the increased malaria

parasitemia in the primigravidae (Okwa 2003 Okpere

2004 Bassey et al 2007 Agomo et al 2009) This

study buttresses the significance of aggressive

awareness campaigns on health education and family

planning in the rural settings because effective health

education at the grass root level would project the

country faster in actualising her millennium

development goal of health for all by the year 2020

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

four groups Blossom-end rot in BSS282 Tima and TO4 were less than others

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

277

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract In order to evaluate genetic variations of tomato genotypes an experiment carried out in Kahriz station during two

seasons in 2010-11 Experimental design was randomized complete blocks with three replications Combined analysis of

variance showed that for agronomic and quality related traits were significant differences Selb-Jino TO2 Early-Urbana

Carmina Cal-J-N and Falat-Shof with more than 105 kgm2 had the highest fruit yield With increasing fruit number per plant

decreased fruit weight Carmina had 170cm plant height and indeterminate growth TO4 Chase Selb-Jino and Carmina with

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

and Carmia Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino were the lowest values Fruit firmness of cultivars was in

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

more than 52 had the most total soluble solid Cluster analysis classified genotypes in two groups Flower inflorescence had

the most significant regression coefficient (063) with fruit yield Two first components explained 97 of total variations in

principal components analysis Correlation coefficients of fruit yield with fruit number at per plant (r=049) number of flower

per inflorescence (r=048) were positive significant differences With delaying fruit maturity decreased fruit number (r=-

078) increased fruit weight (r=080) and pH (r=071) Therefore genotypes with more fruits had low pH (r=-075)

From the point of fruit shape Carmina Nina Selb-Jno and BSS282 were quite uniform TO4 and TO2 had the most fruit color

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

1 INTRODUCTION

Tomato (Solanum lycopersicum L) is a dicot

herbaceous and has different vegetative period as well

as influenced by environmental conditions (Naika et

al 2005 Kahlo 1991 Akinfasoye et al 2011) It is

known as an important source of vitamins and

minerals due to adequate vitamins A and C calcium

and iron Tomatos fruit is consumed in providing

salads and cookies In addition it is used to can paste

ketchup sauce puree and fruit juice (Maitidevi and

Kathmandu 2008) The approaches to make

significant improvement in tomato productions

require information regarding nature and magnitude of

genetic variation and their interrelationships in the

available germplasm which are important pre-

requisites for systematic breeding programs Several

researchers have emphasized the utility of the

estimates of genetic components such as coefficient of

variation heritability and expected genetic advance in

the prediction of response quantitative and qualitative

traits to selection Golani et al (2007) in evaluating

tomato genotypes with path analysis confirmed that

fruit weight had highest positive direct effect followed

by number of carpel per fruit Wessel-Beaver (1992)

pointed out that heritability and genetic correlations in

tomato was high for fruit set yield and fruit weight

Although many of resistant genes are still

undiscovered but in evaluations of wild types

identified drought salinity stresses and insect

tolerance damage of genes (Passam et al 2007

Hanson et al 2000) Presently there are demands for

improved cultivars for growing under greenhouse and

field conditions for different consumes In Iran

planting area and production of tomato were about

150 thousand hectare and 57 million ton respectively

in year of 2011 (FAO 2012) West Azerbaijan

province with 5 thousand hectare under planted area

of tomato and production of 163 thousand ton was one

of the important areas

Evaluation of tomato germplasm collected from

different parts of Kenya showed wide variation in

morphological agronomical and biochemical

characterizations (Stevens 1986) These variations

were due to genetic and environmental differences

Also fruit weight was negative significant correlated

with fruit number at per plant In contrast it had

positive correlation with length and width fruit The

objective of this study was to evaluate genetic

variations of quantitative and qualitative

characteristics of twenty-five tomato genotypes

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

The solutions of equation (2) gives the values of

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

seems that superior genotypes of each group with

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Seeds obtained from seed and plant improvement

institute and planted in single rows When seedling

had 4 to 5 true leaves transferred into the field

Based on soil analysis one-third of recommended

nitrogen fertilizer and total amount of potassium

phosphor and iron and magnesium soleplate zinc

cupper added to soil before planting at late April

Then soil ploughed and disked Rows created with

120cm distance Two-thirds of remaining nitrogen

added before flowering and fruit set stages The

design arranged as randomized complete blocks with

three replications Each plot had 3 rows with 5m

length Insects and fungi controlled with Zineb and

Diazinon 02 and 01 respectively

During growth period three types of quantitative

traits including plant height flower per inflorescence

fruit per plant fruit weight carpel per fruit and days

to first fruit maturity determined from randomly

selected six plants at each plot according to Tanksley

(2004) Fruit yield measured from each total plots

such as mentioned by Al-Aysh et al (2012) Total

soluble solid fruit pH recorded at related qualitative

traits of category methods of according to Majidi et al

(2011) and Ajayi and Olasehinde (2009) respectively

Descriptive traits including fruit uniformity fruit

color fruit firmness fruit shape blossom end rot

sunscald and fruit crack were determined according to

Stevens (1986) Frary et al (2003) Okmen et al

(2011) Passam et al (2007) IPGRI (2003) and Kallo

(1991) respectively Combined analysis of variance

and multivariate analysis for traits of two years done

with SAS and SPSS soft wars Means compared with

Duncans multiple range tests

3 RESULTS AND DISCUSSIONS

Combined analysis of variance showed that

interaction between year and genotype for traits of

fruit yield number of fruit at per plant fruit weight

total soluble solid and days to first fruit maturity

significant differences (ple005) (Table 3) Significant

interactions of traits demonstrated that genotypes had

different responses at two years under field

conditions It can be used in breeding programs for

selecting superior genotypes

31 Agronomic traits

At first year genotypes of Selb-Jino and Falat-Shof

had the highest fruit yield with 112 and 118kgm2

respectively In addition TO2 Early-Urbana Carmina

and Cal-J-N with more than 105kgm2 fruit yield

were the highest values at the second year In

opposite Early-Urbana-VF Falat-Y at 2010 season

and Pri-Max and Cal-J genotypes at 2011 season with

less than 8kgm2 fruit yield had the lowest values

(Table 4) Fruit yield is the genotypic trait which

varies from line to line and clone to clone The result

of Hussain et al (2001) was in confirmation with our

statement of fruit yield differences for different

cultivars

Selb-Jino with 354 and 262 fruit per plant had the

maximum amounts at 2010 and 2011 years

respectively With increasing fruit number at per plant

decreased fruit weight Also Selb-Jino had lower fruit

weight Falat-Y and Pri-Max with 34 and 33 had the

minimum fruit at per plant respectively (Table 4)

Researchers reported that genotype and environment

interaction was not important for fruit weight

(Wessel-Beaver 1992)

Super-Stone with 106g fruit weight at 2010 year

and King-Stone Primo-Early and Falat-Shof with

more than 108g fruit weight at 2011 year allocated the

highest values In contrast Selb-Jino had the lowest

value with 16 and 14g fruit weight at two years

respectively

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

The solutions of equation (2) gives the values of

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

King-Stone with 53 carpel had the highest

amount Also Super-Srin-B Early-Urbana-Y TO4

and Nina had more carpel in per fruit In opposite

Selb-Jino and Cal-J-N with 24 carpel in per fruit

allocated the lowest values (Table 5) Existence of

high heritability for carpelfruit implies that there is

less influence of environment and consequently

selection can be effective for this trait (Asati et al

2008)

Table 4 Mean comparison of interaction between years and tomato genotypes

Carmina with 170cm length had the highest plant

height and Falat-CH Primo-Falat Shof and TO2 were

lower plant height (68cm) Carmina due to

indeterminate growth and high plant height is

suggested for greenhouse cultivation Lerner (2009)

also reported that indeterminate tomatoes increase in

height throughout the growing season because the

terminal of the stem continues to produce foliar

growth rather than set flowers The flowers and thus

fruits on these plants are produced continually through

the season along the side shoots of the plant

Indeterminate tomatoes are the choice to spread out

the harvest over a long period of time Short height

cultivars due to take low spacing under field

conditions therefore with increasing plant density

arise fruit yield Also these cultivars have determinate

growth similar maturities and selected for

mechanized cultivation

Selb-Jino with 78 flowers at per inflorescence was

significant differences with other genotypes The

effect of environmental parameters on this trait is low

and affected by genetic control (Zdravkovic et al

1998)

Cal-J-N Nina Super-Srin-B Pri-Max with more

than 127 days and Selb-Jino with less than 112 days to

first fruit maturity were lateness and earliness

genotypes respectively Lerner (2009) categorized

tomato cultivars in to early mid and late seasons in

regards to time of ripening In our experiment

genotypes with 127 and 112 days to ripening were

lateness and midness maturities respectively

Cluster analysis classified 25 genotypes in two

groups (Figure 2) Discriminate analysis also

confirmed results of cluster analysis (Table 6) At first

group Cal-J-N Falat-Y BSS-282 TO4 Shof Falat-

Primo Early-Urbana and Nina and at the second

group Super-Stone TO2 King-Stone Tima Chase

Peto-Early-CH Primo-Early Cal-J Falat-CH Early-

Urbana-VF Falat-Shof Primax Falat Early-Urbana-

Y Super-Srin-B Selb-Jino and Carmina were located

Genotypes in the second group had more than total

mean fruit yield (Table 7) Also superior genotypes at

first group included TO4 Nina Primo-Early Cal-J-N

Falat-Shof had more than total mean fruit yield It

seems that superior genotypes of each group with

genetically distant cross for increasing hetrosis in

breeding programs

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

The solutions of equation (2) gives the values of

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

At first year of experiment genotypes of TO4 Chase

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

The two-dimensional (2D) quadratic interpolation

polynomial used in this study is based on the general

2D interpolation polynomial

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

The solutions of equation (2) gives the values of

the coefficients of equation (1) For the aquifer model

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Evaluation of Genetic Variations of Tomato Genotypes (Solanum lycopersicum L) with Multivariate Analysis

278

Fig 2 Cluster analysis of 25 tomato genotypes based on different traits

To determine the most effective traits on tomato

fruit yield and better explain relationships of its

stepwise regression used Number of flower in

inflorescence had the most regression coefficient with

fruit yield (063) and remained in the final model

(Table 8)

Table 8 Regression coefficients of related trait with fruit yield in tomato genotypes

Principal components analysis explained 97 of

total variations by the first two components (Table 9)

At first component that more than 86 of total

variations can be explained fruit yield at per plant

with 094 eigen vector had the maximum value (Table

10) Therefore it is named yield components

Genotypes within component that had high variations

for yield components and could be selected for

increasing fruit yield were Early-Urbana-VF TO4

Selb-Jino and Falat (Table 11) At second component

that more than 1096 of total variations can be

explained plant height with 099 eigen vector had the

maximum value Therefore second component is

component of morphological traits Carmina had the

most value at this component Its indeterminate

genotype and had high plant height which

recommended for cultivation under greenhouse

conditions

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

thereby obtaining a system of equation of the form

The solutions of equation (2) gives the values of

the coefficients of equation (1) For the aquifer model

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

32 Related quality traits

At first year of experiment genotypes of TO4 Chase

and Selb-Jino with 58 56 and 55 and at the

second year Carmina and Selb-Jino with 56 and 52

had the most total soluble solid in fruit Early-Urbana-

Y and Tima were the lowest values with 39

Soluble solid is one of the most important quality

traits in processing tomato 50 to 65 of soluble

solid contents are sugars glucose and fructose and

their amount and proportion influences the

organoleptic quality of tomatoes (Adedeji et al

2006) Remaining soluble solid are mainly citric and

malic acids lipids and other components in low

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

concentrations Variations of soluble solid in wild

varieties were more than cultivated (Kallo 1991)

Purkayastha and Mahanta (2010) reported that soluble

solid varied in genotypes from 41 to 59 High total

soluble solid is desirable to higher yield of processed

products Genotypes were also different in terms of

fruit pH Cal-J-N and Selb-Jino with 42 and 38 were

the highest and lowest pH respectively Other

genotypes had between them Selb-Jino due to has

low pH and pathogen activity in processed products it

may be used to preparation of pickles One of the aims

of selection cultivars in tomato were adequate soluble

solid pH and suitable flavor of fruits for processing

Botulism disease delayed in tomato products at lower

pH than 45 (Agong et al 2001) In ripen fruits acid

content was high enough to prevent botulism diseases

Agong et al (2001) introduced pH and soluble solid

as the main criteria for assessing related quality traits

in tomato

33 Descriptive traits

In selecting superior tomato genotypes

morphological market-demand and tolerance to biotic

and abiotic stresses were important From the point of

fruit shape genotypes characterized in six groups

including round long round shaped heart

cylindrical oval and vary-form Shapes of long round

and vary-form had the highest and lowest frequencies

(Table 12) Researchers reported that wild and semi

wild forms of tomatoes bear fruits that are almost

invariably round whereas cultivated tomatoes come

in a wide variety of shapes round oblate pear-

shaped torpedo-shaped and bell pepper-shaped

(Tanksley 2004)

From the view of uniformity fruits placed in to

quite uniform uniform relatively uniform and non-

uniform More genotypes were in relatively uniform

(Table 12) For increasing market-demand and

reduction of harvesting costs large fruits with high

color intensity tart and synchronized mature is

preferred to indeterminate growth and non-uniforms

(Bennett et al 2000)

Fruit color of genotypes distinct in light red

medium red dark red very dark red groups (Table

12) TO4 and TO2 had the most fruit color and Carmia

Falat-CH Super-Srin-B Shof Falat-Y and Seb-Jino

were the lowest values With increasing fruit red color

will be market-demand and paste and sauce be pretty

color Fruit color in tomato is being formed from

lycopene and carotene pigments In red tomatoes

predominant lycopene pigment and inversely in

orange fruit tomatoes carotene has in high value (Hart

and Scott 1995) Wild species may have more

lycopene as commercial cultivars (Dorais et al 2001)

Besides being influenced by genotype some fruit

constituents also influenced by environmental

conditions For example lycopene contents were

strongly affected by light intensity and temperature

(Davies and Hobson 1981)

Fruit firmness of cultivars was in four groups of

soft relatively stiff stiff and very stiff More of

cultivars located in relatively stiff group (Table 12)

Ability of transport and storage capability is important

in tomato Varieties with soft tissue have less

maintenance rapid decayed and damaged in

mechanized harvest therefore must be immediately

consumed (Kallo 1991) Blossom-end rot in

genotypes of BSS282 Tima and TO4 decay rate due

to drought stress and lack of calcium absorption were

less than other genotypes

Table 12 Descriptive traits of tomato genotypes

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 273-284 2013

281

Sunscald was seen in first harvesting Genotypes

grouped in three less low and medium sunscald

Super-srin-B Early-Urbana-Y Nina Falat-Y Tima

TO2 and Falat-Shof had medium sunscald (35 fruit at

per plot) and Falat-CH TO4 Primo-Early Peto-Early-

CH Early Urbana-VF Cal-J Cal-J-N Shof and

BSS282 had less than 10 fruit Genotypes with more

foliage prevented directly radiation and then fruits

didnrsquot damage for sunscald (Lerner 2009) Low

percentage of fruit cracking observed in more

genotypes and in Selb-Jino Cal-J TO2 Carmina and

Early-Urbana had more amounts Fruit crack like

blossom-end rot increased in drought stress and

subsequently decreased market-demand and shelf-life

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

Table 13 Simple correlation coefficient traits of tomato genotypes

and were significant at plt005 and plt001 respectively

Table 14 Canonical correlation coefficient analysis for traits of tomato genotypes

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Sarwar

Valuation of Some Aromatic Rice (Oryza sativa L) Genetic Materials to Achieve Tolerant Resources for Rice Stem

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

(Kallo 1991)

34 Correlation coefficient of traits

Fruit yield with fruit at per plant (r=049 plt005) and

number of flower at per inflorescence (r=048 plt005)

were positive and with days to first fruit maturity (r=-

046 plt005) was negative significant differences

(Table 13) Fruit yield in tomato obtained from

multiplied plant density number of fruit at per

inflorescence and fruit weight (Zdravkovic et al

1998) Increasing one of components reduce other

portions Number of fruit at per plant correlated with

number of flower at per inflorescence (r=095

plt001) Golani et al (2007) showed that fruit yield

with number of fruit at per plant correlated positively

but contrary related with fruit weight Blay et al

(1999) introduced number of fruit at per plant the

most important part in fruit yield By increasing

number of fruit at per plant decreased fruit weight (r=-

085 plt001) and carpel in per fruit (r=-046 plt005)

With delaying fruit maturity decreased fruit number

(r=-078 plt001) and increased fruit weight (r=080

plt001) and fruit pH (r=071 plt001) Therefore

genotypes with more fruits had low pH (r=-075

plt001) Soluble solid with fruit weight (r=-055

plt001) and fruit number at per plant (r=050 plt001)

were negatively and positively significant differences

Thus with increasing number of fruits at per plant

increased fruit soluble solid and in heavy and large

tomatoes decreased total soluble solid Researchers

reported negative correlation between fruit weight and

total soluble solid (Golani et al 2007) Canonical

correlation coefficients between quantitative and

qualitative traits were not significant differences

(Table 14) Fruit yield and fruit soluble solids had the

most coefficients in bellow equation It seems that

between fruit yield from quantitative traits and fruit

soluble solids from related qualitative traits had

negative relationship that observed in simple

correlation coefficients

Y= 1508(fruit yield) + 0766(fruit weight) +

0552(fruit per plant) - 1804(fruit soluble solids)

4 CONCLUSION

Results showed that for selecting a genotype not only

fruit yield but also fruit quality fruit size shape and

color must be considered before choosing Market-

demand and shelf-life appeared stronger criteria for

genotype selection This could be better for most

tomatoes produced for both local and distance market

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

The solutions of equation (2) gives the values of

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

E-mail drmsarwar64yahoocom

Received 25 July 2013 Accepted 2 September 2013

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

Key words Paddy Cultivation Rice Stem Borer Pest Control Scirpophaga Sustainable Agriculture

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract For selection of aromatic rice (Oryza sativa L) lines fifteen (15) genotypes (Graminales Poaceae) were evaluated

for insect pests detection and agronomic characteristic through field test The rice stem borer incidence was recorded according

to deadhearts whiteheads and grain yield parameters from the natural pest infestation In general the results on abundance and

diversity of pestrsquos species at different stages of crop growth revealed the yellow stem borer Scirpophaga incertulas (Walker)

(Lepidoptera Pyralidae) as most dominant insect pest On the basis of percent damage none at all rice genotypes were totally

free from stem borer damage and results showed significant differences (Plt 005) for the selected traits These results

demonstrated that evaluation of rice genotypes conducted for stem borer tolerance showed resistance reactions by the genomes

viz Basmati-15-15 Jajai-25A Basmati-15-13 and CR-33 These four genotypes possessed better antixenosis against adult

egg laying and antibiosis for larval survival of stem borer as compared to the susceptible genome These genotypes can be used

in resistance development breeding program and should be admired in stem borer endemic areas But the genotypes Basmati-

20-300 Basmati-20-400 Basmati-15-3 and CR-12 were highly susceptible to borerrsquos incidence with a corresponding

reduction of paddy yield The present study implies that the tolerant elite lines are able to minimize yellow stem borerrsquos

damage and could be readily used in breeding program to release aromatic rice varieties with significantly improved paddy

yield

1 INTRODUCTION

A number of insects have been reported to ravage the

rice fields of Pakistan but the most important pests

are rice stem borer species belong to genus

Scirpophaga of family Pyralidae under the Order

Lepidoptera that are serious constraints of regular

occurrence in affecting rice crop The rice stem borers

cause injury to the crop at every phase of crop

development their larvae bore into stem feed on the

inner tissue and usually one larva occurs per tiller

The damage symptoms due to stem borer larvae on

affected plants differ with the development period at

which plant infestation is initiated The feedings of

larvae cause deadheart symptoms at the vegetative

stage and the rice plants may be capable of

recompense the damage during the stage of maximum

tillering During the reproductive stage the feedings

of larvae particularly in panicle initiation and earhead

emergence cause whitehead symptoms and with

heavy infestation resulting profound loss in yield The

last instar borer larvae create an outlet hole and pupate

in a silken cocoon inside the larval tunnel at the base

of rice plant (Sarwar 2012 a 2012 b) Damage at the

elongation stage usually does not produce such

symptoms but affects plant elongation capability

resulting in the loss of stem in the rising flood water

(Islam 1990) The damage is caused by caterpillars

only which bore into the leaf sheath and destroy the

growing tips by feeding the internal contents This in

turn disrupts the flow of water and nourishment to the

plant thereby causing drying of central shoot during

vegetative stage When the infestation occurs at the

flowering stage the earheads become chaffy (Jadhao

and Khurad 2012)

Yellow stem borer Scirpophaga incertulas

(Walker) (Lepidoptera Pyralidae) a monophagous

pest of paddy is considered as most important

nuisance of rain fed low land and flood prone rice

eco-systems (Deka and Barthakur 2010) It is one of

the major pests in all rice producing areas of the

world Globally yellow rice stem borer alone causes

yield losses of 10 million tones and accounts for 50

of all insecticides used in the rice field (Huesing and

English 2004) Rice plants are vulnerable to the

yellow stem borer during the booting phase when

infestations cause the greatest yield loss Stem borer

feeding route depends on plant phenology larvae are

more likely to feed on the panicle than on vegetative

structures on booting heading and flowering tillers

Because larvae feed on the panicle resistance during

the booting phase may be effective if it reduces the

likelihood of panicle feeding or if strong antibiotic

resistance can be found in the panicle (Yolanda and

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Valuation of Some Aromatic Rice (Oryza sativa L) Genetic Materials to Achieve Tolerant Resources for Rice Stem

Borers (Lepidoptera Pyralidae)

286

Romena 2006) Unlike other rice stem borers S

incertulas is well adopted to the aquatic deep-water

rice environment (Islam and Catling 1991)

At the present time farmers frequently use

chemical pesticides for the control of this pest

(Kudagamage and Nugaliyadde 1995) This reliance

on use of chemical pesticides leads to numerous

undesirable consequences Host plant resistance is

identified as the most effective way of stem borer

management in various regions Quite a lot of high

yielding rice cultivars having manifold resistances to

the insect pests have been developed and utilized in

the rice growing systems The varietals resistance is

the mainly inexpensive least problematical and

ecological friendly advantageous approach for the

control of insect pest damage Host plant resistance

has been emphasized as a major tactic in integrated

pest management for the motive of its monetary and

environment friendly benefits (Sarwar 2012 c) It is

critical to widen resistant varieties possessing

deviating genetic background to sustain a durable

resistance in the field and for that motivation the

assessment of rice varieties for resistance to stem

borer should continuously be done Therefore it is

important to identify new sources of high and broad

spectrum resistance for rice breeding against stem

borers The present trial is therefore undertaken in

order to evaluate new resistance resources for pestsrsquo

detection and yield characteristic through field test

2 MATERIALS AND METHODS

21 Field site and plant material

The material used in the study comprised of fifteen

(15) aromatic rice genotypes grown in agro-ecological

zone of Sindh province of Pakistan These genotypes

were evaluated during planting season of 2008 at

Pakistan Atomic Energy Commission Nuclear

Institute of Agriculture Tandojam town located in

periphery of Hyderabad The germplasms comprising

Basmati-15-15 Basmati-15-16 Basmati-20-300

Basmati-20-400 Basmati-15-3 Basmati-15-13

Basmati-25-4 Jajai- (P) Jajai-15-1 Jajai-25A

Khushboo Mehak CR-12 CR-33 and CR-34 were

taken from Plant Breeding Division of same Institute

The experimental field was weed or stubble cleared

mechanically then disc ploughed and disc-harrowed

afterward All genotypes were appraised for pestsrsquo

incidence and grain yield attributing character

following randomized complete block design with

three replications For each replicate of a genotype an

area of 3 m2

was specified with a 2 m path

demarcating each replicate The seedlings of all rice

germplasm were raised in nursery seedbed and 30 day

old seedlings were transplanted in the field Spacing

of 30 cm was maintained between the rows and 15 cm

among the plants The crop was raised as per the

recommended package of practices and all cultural

operations were done as and when needed In this

trial only varietals resistance of these genotypes to

rice stem borers was observed and no chemical

control agent was used

22 Identification of varietals resistance

These germplasms were classified into different types

based on the stem borerrsquos incidence recorded

according to deadhearts whiteheads in the crop during

vegetative and reproductive stages respectively and

grain yield parameter at harvesting from the natural

infestation Generally stem borerrsquos incidence was

determined from the presence of deadhearts (larvae

bore leaf sheaths and stems causing dried-up of

central shoots of tillers) or whiteheads (larvae cut the

growing parts resulting in a white or dry empty

panicle) or both in each replicate of a genotype The

borerrsquos incidence was recorded at experimental site as

deadhearts 30 and 60 days after transplanting and as

whiteheads near harvest Just before the booting stage

deadhearts observations were taken from 1 m2

randomly selected area of each replicate of a genotype

by counting the total number of tillers and tillers

showing deadheart symptoms Whitehead counts were

taken one weak before the rice harvesting from each

replicate of a genotype For observation recording the

total numbers of productive tillers were counted then

numbers of damaged panicles found The percentage

deadhearts and whiteheads incidence were computed

by using the counting of total tillers and those with

deadhearts and whiteheads infestations Grain quality

and yield attribute data were obtained after harvesting

the rice crop at the experimental field After

harvesting the seeds of each rice genotype were used

to evaluate agronomic characteristic

23 Analysis of data

The data recorded on paddy yield percentage

deadhearts and whiteheads were subjected to

statistical analysis for characterization using Statistix

81 software All the means were then compared using

analysis of variance at 5 significant level

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

dominant insect belonging to the Lepidopteron family

Pyralidae Higher proportion of pest larvae dispersed

from vegetative rice plant than booting plants This is

linked to the alteration of phenological of rice crop in

relation to different stages of growth Definitely odor

and growth of plants acted as specific line to the

larvae for crop During the vegetative stage the

numbers of tillers enhanced and the greatest numbers

were achieved ahead of the booting stage Further at

booting stage the rice tillers had larger stem diameter

and for that reason made certain relatively better

quantity of food resources and tendered larger

survival value to the population of larvae Typically

within a single tiller one larva was found near to

apical growing area of the plant in comparison to the

other segment of the plant tissue This is due to more

rigidity and less palatability of the plant tissue

comparatively at the apical growing area of the plant

At booting heading and flowering growths of tillers

stem borer feeding route also depended on plant

phenology The larvae were more likely to nourish on

the panicle compared to vegetative portions

32 Identification of varietals resistance

In this experiment the reactions of the rice

germplasms to stem borer infestation are presented in

Table 1 In general the result of experiment showed

that most of the germplasms were found to give minor

to moderate type of resistance against stem borers

Only four genotypes had slight deadhearts and

whiteheads infestations and four had heavy incidence

With respect to deadhearts spreading values four

genotypes Basmati-15-15 Jajai-25A CR-33 and

Basmati-15-13 having a score of 395 447 457 and

484 respectively were exceedingly tolerant But

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 captured more mean values of deadhearts

(1030 918 811 and 778 respectively) proving

susceptible and significant variations were observed

among the genotypes

Regarding whiteheads Basmati-15-15 Jajai-25A

Basmati-15-13 and CR-33 had the minimum mean

values for this trait (597 681 758 and 777

respectively) Meanwhile the germplasms viz

Basmati-20-300 Basmati-20-400 Basmati-15-3 and

CR-12 had abundant infestation of stem borer (1472

1331 1290 and 1289 whiteheads respectively)

and were categorized as susceptible to the pest

Regarding paddy yield Basmati-15-15 Jajai-25A

CR-33 and Basmati-15-13 had the minimum mean

values for this attribute (15117 14250 14000 and

13900 gm per 3 m2 respectively) with a good grain

quality On the basis of paddy yield only four

varieties viz Basmati-20-300 Basmati-20-400

Basmati-15-3 and CR-12 could recorded significantly

less produce (7517 8333 8617 and 8667 gm per 3

m2 respectively) which were more infested and

produced fewer grains This study showed that there is

a great diversity of volatiles in aromatic rice cultivars

and with further research this may lead to a better

understanding of the combination of compounds that

give a cultivar an unique tolerant

4 DISCUSSIONS

The screening of fifteen (15) aromatic rice

germplasms led to the identification of some

genotypes with natural resistance to the stem borer

Resistance to stem borer in Basmati-15-15 Jajai-

25A Basmati-15-13 and CR-33 appeared to be due to

the presence of a strong repellent or a lack of feeding

stimulus in the plants and either due to the presence

of toxic materials or nutritional deficiencies in the

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Valuation of Some Aromatic Rice (Oryza sativa L) Genetic Materials to Achieve Tolerant Resources for Rice Stem

Borers (Lepidoptera Pyralidae)

plant for the insect In nature to reduce insect pestrsquos

damage plants may make use a variety of resistance

types Generally the plant resistance to insects is

distinguished as antibiosis (reductions of insect

survival growth rate or reproduction subsequent to

ingestion of host tissue) tolerance (despite insect

infestation capacity of a crop to produce high quality

yield) and antixenosis (quality of plant to repel or

disturb insects to reduce their colonization or

oviposition) (Alam and Cohen 1998) All the three

categories of resistance are observed against bores in

rice germplasm Similar to this study other

investigators (Abro et al 2003 Khan et al 2010

Sarwar et al 2010 Sarwar 2011 and Sarwar 2012

d) also recorded differential behavior of rice cultivars

to borerrsquos infestation in Pakistan The results revealed

that larval damage varied significantly with varieties

of rice and that among traditional basmati growing

areas stem borers are a great threat and in certain

cases crop is left un-harvested in the field due to the

cost of harvesting being higher than the attainable

yield

Evaluation of some selected rice germplasms was

conducted in this trail in the natural infestation of

lepidopteron insects The estimates obtained based

upon parameters of stem borer incidence (deadhearts

or whiteheads and yield) showed resistance reactions

in some genotypes these promising plant materials

ought to be popularized in stem borer prevalent

regions and can be used in varietals breeding program

Moreover in field conditions these results

demonstrated the expression of the resistance genome

of rice that can provide season-long protection from

the infestation of lepidopteron insect pests Rice plant

is susceptible to the yellow stem borer S incertulas

throughout the booting stage when infestations

caused the greatest yield loss from the natural

infestation Since larvae fed more on the panicle so

resistance in rice may be more effective throughout

the booting period if strong antibiotic resistance can

be found in the panicle to reduce the likelihood of

panicle feeding The identical observations were given

by earlier investigators (Yolanda and Romena 2006

Satpathi et al 2012) on feeding patterns of S

incertulas on rice during the booting stage

Numerous physical and chemical

characteristics of rice were evaluated to determine

which character would be the best to assess multiple

rice varieties for resistance breeding to the borers A

significant positive correlation was observed between

different corrected damage ratings and leaf width and

chlorophyll content in rice leaves whereas no

significant correlations between resistance and plant

height and leaf length were found (Xu et al 2010)

Results of the study showed that mechanism of

tolerance were affected by the plant height and

amount of chlorophyll on antixenosis mechanism

stem diameter and number of tillers on antibiosis

mechanism (Hosseini et al 2011)

Previous reports have proposed that the mechanism

of tolerance for the insect depends upon many factors

occurring that time and environmental conditions are

also more important and effective Resistance to stem

borers appears to be under polygenic control (Khush

1984) Many morphological anatomical

physiological and biochemical factors have been

reported to be associated with resistance each

controlled by different sets of genes (Chaudhary et al

1984) Some varieties have added resistance caused

by the presence of minor genes however in future it

is possible to determine which resistance genes are

still effective against the local borer populations To

verify whether one or many genes exist in the tolerant

genotypes they ought to intercross in reciprocal

directions to study inheritance of resistance Further

research is required to conclusively determine the

allelic relationships of resistance genes in the tolerant

genotypes

5 CONCLUSION

Presently through rigorous testing of some rice

germplasms for resistance to stem borers few

resistant genotypes are identified Because the data

confirming the occurrence of the new rice genotypes

resistant to borers are somewhat small so the

inclusion of resistance to the better rice varieties is

crucial Resistance noted among these genotypes

could be owing to previously recognized resistant

genes or else attributable to new genes Hence more

experiments ought to be conducted with markers for

previously recognized resistant genes to perceive

whether the resistance noticed in rice germplasms is

as a result of existing resistant genes or new genes to

keep away from genetic homogeny of borer resistance

in rice Their identification and characterizing may

support for upcoming transfer of genes into a wide

range of commercial rice cultivars The results of

genetic stocks must facilitate in understanding pest

resistance categories of rice to set a solid foundation

for breeding new resistance varieties

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract Environmental flow is necessary for securing ecological health status of a river Around the Dhaka city of

Bangladesh the Turag an ecologically critical area is an important river Environmental flow assessment of the Turag can help

to sustain ecosystem and navigation in it The aims of the research are to estimate environmental flow of the Turag and to

assess current flow condition Mean daily discharge data recorded by Bangladesh Water Development Board had been

collected and analyzed for two periods (1989-2004) and (2005-2009) Mean Annual Flow (MAF) Flow Duration Curve (FDC)

and Range of Variability Approach (RVA) methods were used and IHA software had been exercised in calculating

environmental flow According to RVA FDC and MAF methods estimated environmental flow was found to be 19272 cms

2065 cms and 18077 cms respectively with the mean of 19272 cms It is observed that in more recent time the

environmental flow is not maintained during the low flow season in the river and overall flow rate is reduced Mean maximum

and minimum annual flows are reduced about 35 42 and 9 respectively from the period (1989-2004) to (2005-2009)

Considering environmental flows estimated by RVA and MAF methods about 40 and 36 of total flow of the period 2005-

2009 flowed below the required environmental flow In FDC method about 35 flow is flowed below the required

environmental flow during the low flow season in the same period These findings may help the policy makers to manage

water resources in the catchment area of the Turag

1 INTRODUCTION

Variability of river flow influences water quality

energy cycles biotic interactions and habitat of rivers

(Naiman et al 2002) More recent time the river

scientists refer to the flow regime in freshwater

systems as a master variable due to its strong

influence on the environmental factors eg water

chemistry physical habitat biological composition

and interactions (WB 2008) Minimum flow in rivers

and streams is necessary to provide a certain level of

protection for the aquatic environment (Jowett 1997)

Although human manipulation of river flow provides

many societal benefits it also degrades and eliminates

valuable ecosystem services and threatens freshwater

biodiversity (Bunn and Arthington 2002 Magilligan

and Nislow 2005) There is now widespread

understanding that the environment is a legitimate

user of the river The environmental flow or the

provision of water within rivers to conserve

freshwater biodiversity while meeting the water

demand of human society is needed for most riverine

systems (Brown and King 2003) To evaluate the

ecological effect indicators are needed to evaluate the

overall ecological health of the river and the degree of

hydrologic alteration caused by a particular operating

policy (Gao et al 2009)

It is possible to describe flow regime in terms of

environmental flow components Environmental flows

are a regime of flow in a river or stream that describes

the temporal and spatial variation in quantity and

quality of water required for freshwater as well as

estuarine systems to perform their natural ecological

functions including sediment transport and support the

cultural and livelihood activities that depend on these

ecosystems (Tare 2011) The health and integrity of

river systems ultimately depend on these components

which may vary seasonally (Mathews and Richter

2007) Moreover environmental flow is necessary for

securing ecological health status of a river River

health is often equated with bdquobiological integrity‟

which has been defined as ldquothe capability of

supporting and maintaining a balanced integrated

adaptive community of organisms having a

composition and diversity comparable to that of the

natural habitats of the regionrdquo (Frey 1977)

Improved quantitative evaluations of human-

induced hydrologic changes are needed to advance

research on the biotic implications of hydrologic

alteration and to support ecosystem management and

restoration plans (Richter et al 1996) The concept

Rahman et al

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

297

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

292

of environmental flow is relatively new in

Bangladesh Organizations responsible for water

management are becoming increasingly aware of their

responsibilities for environmental protection creating

an increasing interest in methods of assessing flow

requirements for different instream uses (Jowett

1997) Now a day most of the rivers around the main

cities of Bangladesh are polluted because of receiving

huge amount of partially treated and untreated sewage

effluent sewage polluted surface run-off and

untreated industrial effluent from nearby residential

and industrial areas The Government of Bangladesh

(GoB) is solely responsible to maintain environmental

flow in the rivers By imposing importance on the

environmental flow the GoB makes one of the seven

strategies to assess environmental flow requirement

after prioritizing twelve major issuesproblems as the

main sources of coastal and marine pollution (DoE

2007) The capital city Dhaka is surrounded by the

rivers named Balu Buriganga Dhaleshwari

Shitalakhya Tongi khal and Turag (Fig 1) The flow

of the Turag River is the main source of water into the

Buriganga particularly during the dry period (Kamal

1996 Alam 2003) and the Buriganga is the main

navigation route to the southern part of Bangladesh

The Turag River has been declared as ecologically

critical area (ECA) by the Department of Environment

on September 2009 (DoE and LGED 2010)

Present study aims to estimate environmental flow

of the Turag River which can be used for future

reference in management purposes and to assess the

flowing condition of the river through the comparison

between past and more recent time

2 MATERIALS AND METHODS

21 Study area and data collection

The Turag River is the upper tributary of the

Buriganga The Turag originates from the Bangshi

River (Fig 1) The Turag flows through Gazipur

district and joins the Buriganga at Mirpur in Dhaka

district The Tongi Khal links the Turag with the

Balu River (Choudhury and Choudhury 2004) The

entire regime of the Turag is almost a semi-funnel

shaped basin and its catchment is located on the

central and southern part of the Madhupur tract and

flows from north to south within the basin and its

length is about 40 miles and 15 miles in wide to the

maximum The average width and depth of the river

are about 218m and 135m respectively It has a total

area of 386 square miles (Uddin 2005) From 1989 to

2009 mean daily discharge (cms) data had been

collected from Bangladesh Water Development Board

(BWDB) Among these years the supplied data had

been missing for 1994 1995 and 2007

Fig 1 The Turag River and other rivers at the surroundings of the Dhaka city

22 Analysis of flow characteristics

The historical river data had been analyzed under two

periods named P1 (1989-2004) and P2 (2005-2009)

The river characteristics and estimated environmental

flow of P1 were compared with P2 Results are

organized as parametric statistics in which data are

characterized by mean or standard deviation The flow

in the Turag varies from season to season For the

convenience in analysis of the flow data annual flow

International Journal of Scientific Research in Environmental Sciences (IJSRES) 1(10) pp 291-299 2013

293

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

had been characterized in three separate seasons

named low flow season (February to May) high flow

season (July to October) and intermediate flow season

(November to January and June)

23 Estimation of environmental flow

An instream flow policy requires clear and

measurable goals ideally defining the goal (e g

retention of a resource or instream use) the extent to

which this is to be achieved (ie level of protection)

and criteria for evaluating the achievement (Beecher

1990) In practice either the proportion of the flow

wetted perimeter or physical habitat that is retained by

a minimum flow is used as a measure of the level of

protection (Jowett 1997) There are 207 methods

from 44 countries that had been used to assess

environmental flow (Tharme 2003) The different

methods of environmental flow assessment used all

over the world can be grouped into four main

categories hydrological hydraulic rating habitat

simulation and holistic methods (Tharme 2003 and

King et al 2000) Again quantitative instream flow

methods are generally divided into three major

categories historic flow regime hydraulic and habitat

(Jowett 1997) Among these methods hydrological

(or historic flow regime) is the easiest to use and the

required data is only the historic flow records of the

stream concern (Mullick et al 2010) For the research

work Mean Annual Flow (MAF) method (Tennant

1976) Flow Duration Curve (FDC) method and

Range of Variability Approach (RVA) (Richter et al

1997) were used to estimate the environmental flow

which are under the hydrological method In MAF

method environmental flow requirement is set at

different percentage of the mean annual flow that

varies from 10 to 200 The percentage is set

considering the desired habitat quality (Table 1) The

FDC is a very useful tool for assessing the overall

historical variation in flow (Lamb et al 2009) The

RVA method provides a flow target that resembles the

natural flow regime with the primary objective of

protecting natural ecosystem (Mullick et al 2010)

The IHA software (version 71) had been exercised to

acquire required calculation of FDC and RVA to

estimate environmental flow of the Turag River

3 RESULTS AND DISCUSSION

31 General characteristics of the Turag

In the dry season (November to February) the water

flow is the lowest in the Turag By considering mean

monthly annual flows September is the highest

flowing (639 cms for P1 and 5427 cms for P2)

month January is the lowest flowing (2051 cms)

month for P2 and May is the lowest flowing (4102

cms) month for P1 Some other general characteristics

are shown in Table 2

The estimated high and extreme low flow

thresholds for the Turag are 611 and 1939 cms

respectively Comparing with each other P2

significantly reduces high flow and shows larger

portion of flow flows below the extreme low flow

threshold (Fig 2) For P1 about 41 of total flow

flows over high flow threshold that reduces to about

16 for P2 Again the portion of extreme low flow

threshold increases from about 2 to 36 for P1 and

P2 respectively

32 Environmental flow components (EFCs) of the

Turag

The IHA software calculates 34 parameters under 5

groups of Environmental Flow Components (EFCs) as

shown in Table 3 Low flow season (February to May)

is the main concern to estimate environmental flow of

the river Considering EFCs monthly low flows of the

Turag show clear reduction of flow from P1 to P2

(Table 3) According to Julian date of peak flow for

P2 extreme low peak of the Turag occurs during the

pre-monsoon period (at May) however for P1

extreme low peak takes place during the monsoon

period (at September) of Bangladesh Again at

September during the monsoon period small flood

occurs for both P1 and P2 33 Estimation of

environmental flow

331 RVA analysis

In IHA software the RVA targets are computed

setting at +- 1 standard deviation In setting such

target it is implicitly assumed that values within these

limits from the mean are not expected to have

295

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

The solutions of equation (2) gives the values of

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

The solutions of equation (2) gives the values of

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

significant impact on stream ecology (Mullick et al

2010) The RVA targets with mean monthly flow for

two periods (P1 and P2) are presented in Fig 3 It is

clearly seen that at P2 period the Turag flows below

the lower range of RVA which last from December to

May that exceeds the months of the low flow season

(February to May) In this method the Turag should

have at least 2065 cms of flow to meet environmental

flow requirement which is the lowest value of the

lower range of RVA

332 Flow duration curve (FDC) method

A flow duration curve (FDC) represents the

relationship between the magnitude and duration of

stream flows duration in this context refers to the

overall percentage of time that a particular flow is

exceeded In practice FDCs are used mainly in

relation to the setting of environmental flow

objectives In the United Kingdom Q95 flow (the flow

exceeded 95 of the time according to the FDC) has

been used historically to represent the low flow in a

river (Lamb et al 2009) This means that abstraction

is permitted for the flow which is greater than the Q95

In case of Bangladesh Mullick et al (2010) and

Hossain and Hosasin (2011) used 90 (or 90th

percentile) to represent the low flow in the Tista and

the Dudhkumar respectively two northwestern rivers

of the country Again for Bangladesh the mentioned

authors set 50 (or 50th percentile) for high flow

season to determine environmental flow requirement

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

The solutions of equation (2) gives the values of

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Environmental Flow Requirement and Comparative Study of the Turag River Bangladesh

296

Fig 4 Flow duration curve (FDC) for P1 (1989-2004) and P2 (2005-2009) of the Turag

The FDC for the Turag is shown in Fig 4 and the

environmental flow requirement is in Table 4 During

the low flow season the Turag is needed 18077 cms

of water which is maintained by all months of

intermediate and high flow seasons at P1 The

minimum requirement based of FDC method is

retained by P2 during both intermediate and high flow

seasons except low flow season About 35 flows are

flowed below the required environmental flow during

the low flow season of P2

333 Mean annual flow (MAF) method

This method is generally known as Tennant method

The mean annual flow of the Turag is 47719 cms

(Table 2) which is calculated with defined percentage

as described in Table 1 and the results are shown in

Table 5 Although 9544 cms is supposed to meet

environmental flow requirement of the Turag

according to MAF method the result is not close

enough to environmental flow requirement obtained

from other two methods as described earlier During

the low flow season 19088 cms flow requires to

maintain outstanding habitat quality which is closer to

environmental flow requirement for the Turag found

by RVA and FDC methods

34 Change of flow in the Turag

Hydrologic alteration (HA) can be used to determine

change of flow in the river which is calculated by the

IHA software according to the following equation ndash

A positive HA value means that the frequency of

values in the category has increased from pre- to post-

condition (with a maximum value of infinity) while a

negative value means that the frequency of values has

decreased (with a minimum value of -1) (TNC 2009)

From Table 6 it is evident that significant increase in

alteration occurs at P2 for low RVA In case of high

and middle RVAs increase in alternation occurs only

at July and September months respectively and at

other months the RVAs decrease Mean annual flow

maximum and minimum annual flow are reduced

about 35 42 and 9 respectively from P1 to P2

(Table 2) Considering environmental flow estimated

by RVA method only about 3 of total flow flows

below this value for P1 period and about 40 flows

for P2 period

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

The solutions of equation (2) gives the values of

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

From FDC in Fig 4 the change of flow can also

be verified For P2 the annual FDC clearly alters

significantly especially after 375 of exceedance

probability After 85 of exceedance probability

annual FDC of P2 sharply reduces comparing with P1

Again at P2 period significant amount of flow

reduces during low flow (about 66) and

intermediate flow (about 53) seasons and during

high flow season the reduction rate is about 17

(Table 4) In MAF method the river flow also

significantly reduces from P1 to P2 periods Less than

2 of total flow flows below the estimated

environmental flow (19088 cms) for P1 and about

36 flows below for P2 period

4 CONCLUSION

The estimated environmental flow requirement of the

Turag according to RVA FDC and MAF methods are

2065 cms 18077 cms and 19088 cms respectively

By taking average of these values the Turag should

have at least 19272 cms all the year around to meet

environmental requirement or instream demand

Mean maximum and minimum annual flows are

reduced about 35 42 and 9 respectively from

P1 to P2 periods Considering environmental flows

estimated by RVA and MAF methods about 40 and

36 of total flow of P2 period flow below the

estimated required environmental flow Again in FDC

method about 35 flows are flowed below the

required environmental flow during the low flow

season of P2 Therefore in all scenarios the Turag

suffers from significant hydrologic alteration that

reveals reduction of flow in recent time

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

The solutions of equation (2) gives the values of

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

with a mean absolute error of less than 4 between

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

them Thereafter contour and surface maps for Nariya

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

ground surface elevation This also agreed with field

observations and is consistent with similar findings

obtained by Olaniyan et al (2013)

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

and 4 show the contour and surface plots of the

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

Abstract This paper presents the result of a two-dimensional model for predicting groundwater hydraulic head in Nariya

Village Kaduna Nigeria Vertical Electrical Sounding (VES) was employed in investigating the subsurface water level at six

different points (500m to 1km apart) and the result obtained was used to fit a two-dimensional polynomial using Mathcad 14

which satisfactorily predicted the groundwater hydraulic head at other locations on the site Surface and Piezometric surface

contour maps were plotted using the polynomial with Maple 14 software and the modeled result showed good agreement with

the interpreted field data with less than 4 error margin

Key words Groundwater hydraulic head interpolation polynomial vertical electrical sounding

1 INTRODUCTION

11 Background

Groundwater plays an important role in the

development and management of water resources

Hence the increasing need for information on

groundwater hydrology and hydraulics of movement

of water in aquifers (Bear 1979) The actual pattern

of the groundwater level changes in the aquifer is of

great interest to hydrologists irrigation engineers and

related practitioners hence the need to formulate

models both theoretical and mathematical to

accurately forecast the groundwater level

Models for groundwater analysis are powerful

techniques for forecasting the effects on a system

created by causative elements Numerical modeling of

a groundwater basin system involves constituting a

groundwater model that is mainly mathematical in

nature involving the inherent characteristics of an

aquifer Groundwater models are used to understand

the behavior of groundwater systems and predict the

response of an aquifer to any external changes such as

extraction recharge etc The model can also be used

to select the best of several alternative management

plans for a groundwater basin In the final analysis

groundwater models can suggest optimum utilization

of resources and maximization of the overall yield of

the system (Rastogi 2007)

Several mathematical models exist in literature for

determining the water level such as the one- and two-

dimensional Boussinesq equations and have been

solved analytically now numerically for different

boundary conditions and geometries Analytical

models and solutions are often very complicated and

difficult to apply for most water management

practitioners especially because the flow region must

have a well-defined regular shape Therefore such

models may not be accurately applicable to real field

problems But now numerical models have removed

such limitations and hindrances to modeling of any

region of interest irrespective of shape or geometry

For examples of such models one may consult the

works of Hantush (1962) Marino (1974) Bear

(1979) Mustafa (1987) Haruna and Gideon (2005)

Nwaogazie (2008) and Olaniyan et al (2011)

On the other hand experimental methods of

determining groundwater level also exist such as

borehole and well drilling methods vertical electrical

resistivity (VES) etc but these methods are often of

great financial costs Examples of these works include

Carruthers and Smith (1992) Hazel et al (1992)

Adeoti et al (2010) Alile et al (2011) Olaniyan and

Olabode (2012) and several others

The objective of this study is to apply a two-

dimensional polynomial model to field measurements

to determine the groundwater and ground surface

elevations across Nariya area within Kaduna State

2 METHOD OF INVESTIGATION

Vertical Electrical Sounding investigation was carried

out using ABEM terrameter model SAS 300C with its

accessories at six locations using the schlumberger

configuration The maximum array length in the

survey was 200m VES data obtained was interpreted

first by manual partial curve-matching and then by

using automatic program by Zohdy (1989) to

delineate lithology and infer water table hydraulic

heads The six VES points were assigned coordinates

based on their locations with x-axis measured along

the adjoining River Kaduna and y-axis perpendicular

to the river These coordinates and their corresponding

hydraulic head values (Table 1) were used to fit a two-

dimensional interpolation polynomial which was able

to accurately predict the groundwater hydraulic heads

across the entire study area

21 The Study Area

Nariya is a sub-urban settlement to the west of

Kaduna and is located approximately on latitude 10deg

29rsquoN and longitude 7deg 22rsquoE The study area consists

of parts of Nariya bounded to the south by River

Kaduna The climate of Kaduna is the tropical type

which has distinctive wet and dry seasons Annual

rainfall ranging between 1000 to 1500mm occurs

between early April and early October while

maximum temperatures vary between 38oC in

MarchApril and 24o C in other months but becomes

far less in peak rainy periods (JulyAugust) and in

harmattan months (November-February) The Guinea

Savannah type of vegetation in the area consists of

broad-leaved savannah woodland which may attain

heights of about 10 to 15 meters when fully

developed and may be dense enough to suppress the

growth of grasses (Olaniyan and Olabode 2012) The

relief of the area is characterized by an undulating

plain gentle slope and consists of peneplains with

eroded flat tops often capped by layers of indurated

laterites The southern boundary of the study area

adjacent to the river exhibits swampy conditions

during the rainy season while the upper parts drain

freely The drainage pattern is dendritic while stream

flow fluctuates seasonally

The typical rock types underlying the entire land

area of Kaduna State consist of the Precambrian

migmatite-gneiss complex met sediments and

metavolcanics (mostly schists quartzites

amphibolites and banded iron formations) Pan-

African granitoids and calc-alkaline granites and

volcanics of Jurassic age towards the south-eastern

border of the State (Oluyide 1995) Most of the areas

underlain by the Basement Complex rocks in northern

Nigeria consist of a thin discontinuous mantle of

weathered rock overlying them The average thickness

of the mantle is about 15m although depths of about

60m may be encountered The unweathered bedrock is

characterized by rapid grain-size variations from

micro to pegmatitic regions but normal sizes are

dominant The water-bearing units (aquifers) in

Basement rocks occur within the weathered residual

overburden (the regolith) and the fractured bedrock

were plotted as shown in Figures 1 to 4 Figures 1 and

2 show the contour and surface maps of the hydraulic

heads respectively From the result it was observed

that the water table decreases toward the Kaduna

River which agrees with the results of field

investigation and is consistent with similar findings

obtained by Onwuemesi (1990) Similarly Figures 3

ground surface elevation This also agreed with field

observations and is consistent with similar findings

4 CONCLUSION

A mathematical model involving a two-dimensional

interpolation polynomial has been used as a novel to

simulate hydraulic head and ground surface elevations

at Nariya The result from the 2D quadratic

interpolation polynomial was compared with field

data and both the calculated data and the field

measured data showed excellent correlation This

outcome further gives credence to the fact that

mathematical models are effective in depicting and

predicting natural groundwater conditions to a high

degree of accuracy This model is however applied

to Nariya locality and may be used for other localities

provided that the similar hydrogeological conditions

are prevalent

When a function is dependent on two variables

say coordinates equation (1) could be used to

interpolate such data by determining the values of the

unknown constants ia rsquos (Gerald 1977 Rastogi 2007)

The solutions of equation (2) gives the values of

the coefficients of equation (1) For the aquifer model

in the study area the hydraulic heads and the

coordinates of the six VES points were substituted

into equation (1) to obtain the model equation

3 RESULTS AND DISCUSSIONS

The interpreted hydraulic head data presented in

Table 1 was substituted into the hydraulic head

equation (3) to simulate the aquifer hydraulic heads at

other points in the region with the aid of Maple 14

subroutine software The corresponding modeled

values were compared with the interpreted (measured)

values in Table 2 and the absolute errors between the

two values are also indicated The figures in Table 2

shows that the measured hydraulic head values and

the corresponding modelled values are very close
