Soil and climate
Ideal soil for mango is red loamy. Good drainage is
preferable for better establishment. Ideal pH range is
from 6.5 to 8.0.
Season of planting
Planting spreads from July to December.
PROPAGATION
Sexual Propagation:
• Seed
Vegetative Propagation:
• Inarching / approach grafting
• Veneer grafting
• Stone Epicotyl
grafting
• Soft-wood grafting
• Budding
• Air layering
PLANTING
• Time of planting- during the monsoon when there is sufficient moisture in
the atmosphere (July to December).
• Planting distance- The planting distance varies according to variety, the
fertility level of the soil and general growth conditions in the area.
Where the growth is excessive, the distance should be 12 x 12 m, but
in the dry zones where the growth is less, it can be regulated to about 10 x
10 m.
For high density planting, the distance can be 5 x 3 or 5 x 2.5 or 3 x
2.5 or 2.5 x 2.5 m.
• Size of pits- In locations where the soil is loamy and deep, pits of 0.5 x
0.5 x 0.5 m be dug at desired distances. However, in shallow and hill
soils, the pits should at last be of 1 x 1 x 1 m size.
• Filling of pits- The pits should be filled with the original soil mixed with
50 kg well rotten FYM. In the top two-third portion, the proportion of the
manure and soil may be kept as 1:3. If the soil is having infestation of
white ants, 200-250 g of aldrex or BHC dust may also be mixed.
Training and pruning
The training of the plants in theinitial stages is very essentialto give them proper shape.
Rootstock sprouts and lowlying branches (at least 75 cmof the main stem ) have to beremoved.
Remove overlapping,intercrossing, diseased, driedand weak branches in old treesto get good sunlight andaeration.
For the internal branches,pruning may be done duringAugust – September, once inthree years.
Flowering should not beallowed up to three years.
FERTILIZER REQUIREMENTS
• Fertilizers may be applied in two split doses , one half immediately after the harvesting of fruits in June/July and the other half in October, in both young and old orchards followed by irrigation if there are no rains. Foliar application of 3 % urea in sandy soils is recommended before flowering.
•
• The following table gives the details of fertilizer applied (depending upon the age of the plants) :
*The doses applied in the subsequent years should be increased every year upto 10 years in the multiple of the first year’s dose.
• Well decomposed farm-yard manure may be applied every year. For trench application of fertilizers, 400g. each of N and K2O and 200g. of P2O5 per plant should be provided. Micro-nutrients may be applied as per the requirement in the form of foliar sprays.
Age of plants (in year)1*1011
Fertilizer applied100g N, 50g P, 100g K.1kg N, 500g P, 1kg Kdo
IRRIGATION
• Amount and frequency of irrigation depends upon the type of soil, prevailing
climatic conditions.
• No irrigation is required during the monsoon months unless there are long
spells of drought.
• During the first year when the plants are very young with shallow root
system, they should be watered every 2-3 days in the dry season.
• Trees in the age group of 2-5 years should be irrigated at 4-5 days interval.
• The irrigation interval could be increased to 10-15 days for 5-8 years old
plants during dry season.
• When trees are in full bearing stage, generally 2-3 irrigations are given after
the fruit set.
• Profuse irrigation during 2-3 months proceeding the flowering season is not
advisable. Irrigation should be given at 50 per cent field capacity.
• Generally, intercrops are grown during the early years of plantation and
hence frequency and method of irrigation has to be adjusted accordingly.
• It is advisable to irrigate the mango plants in basins around them which can
be connected in series or to the irrigation channel in the centre of rows.
INTERCROPPING
• It is always advisable to avoid tall growing exhaustive crops like maize, sugarcane, bajara, etc.
• Some fertility restoring crops like legumes and leguminous cover crops should be included into the intercropping patterns. The partial shade loving crops like pineapple, ginger, turmeric, etc. can be grown in fully grown orchards.
• In addition to field crops, some short duration, less exhaustive and dwarf type inter-fillers like papaya, guava, peach, plum, etc. can also be grown till these do not interfere with the main mango crop.
• Leguminous crops of like green gram, black gram, gram; etc., cerealslike wheat; oilseeds like mustard, sesame and groundnut and vegetablescrops such as cabbage, cauliflower, tomato, potato, brinjal, cucumber, pumpkin, bitter gourd, lady’s finger, etc. and spices like chillies can be successfully grown as intercrops.
DISEASES
• The characteristic symptom of the disease is the white superficial powdery fungal growth on leaves, stalks of panicles, flowers and young fruits. The affected flowers and fruits drop before attaining pea size.
• Control : Following three sprays of fungicides at 15 days interval recommended for effective control of the disease :
Wettable sulphur 0.2 per cent (2 g Sulfex / lit. water).
Tridemorph 0.1 per cent
( 1 ml Calixin / lit. water).
Dinocap 0.1 per cent
(1 ml / g Karathane / lit. water).
Powdery mildew (Oidium mangiferae )
Anthracnose
• The disease causes serious losses to young shoots, flowers and fruits under favourable climatic conditions of high humidity, frequent rains and a temperature of 24-32oC.
• The disease produces leaf spot, blossom blight, wither tip, twig blight and fruit rot symptoms.
• Cause ‘die back’ of young branches.
• Severe infection destroys the entire inflorescence resulting in no setting of fruits.
• Control: Trees may be sprayed twice with Bavistin (0.1%) at 15 days interval during flowering to control blossom infection. Spraying of copper fungicides (0.3%) is recommended for the control of foliar infection.
Die back (Botryodiplodia theobromae)
• The disease on the tree may be noticed at any time of the year but it ismost conspicuous during Oct.-Nov.
• The disease is characterized by drying of twigs and branches followedby complete defoliation, which gives the tree an appearance ofscorching by fire.
• The areas of cambium and phloem show brown discolouration andyellow gum like substance is found in some of the cells.
• Control :
(i) Prune the diseased twigs and spray with copper oxychloride (0.3%)on infected trees. Pruning should be done in such a way that the twigsare removed 2-3 inches below the affected portion.
(ii) In small plants, pruning of twigs is followed by pasting of copperoxychloride.
PESTS• Control
a) Chemical : Three sprays of 0.15%
Carbaryl or 0.05% Phosphomidon or
0.05% Methyl Parathion have been
found very useful in controlling the
pest population.
First spray should be given at the early stage of panicle formation.
The second spray at full length stage of panicles but before full bloom
The third spray after the fruits are set and have attained pea stage are
recommended.b) Biological : Biological control agents such as the predators Malladaboninensis and Chrysopa lacciperda, the egg parasite Polynema sp. and a preparation of the fungus Beauveria bassiana are the important useful bio agents to control this pest.
HOPPER
Mealy Bug
Control(i) Mechanical : Polythene (400 gauge) bands of 25 cm width fastened around the tree trunkhave been found effective barrier to stop the ascent of nymphs to the trees. The band should be fastened well in advance before the hatching of eggs, i.e., around November - December.(ii) Chemical : Application of 250 g per tree of Methyl Parathion dust 2% or Aldrin dust 10% in the soil around the trunk kills the newly hatched nymphs which come in contact with the chemical.
Spraying of 0.05% Monocrotophos or 0.2% Carbaryl or 0.05% Methyl Parathion have been found useful in controlling early instar nymphs of the mealy bug.(iii) Biological : Menochilus sexmaculatus, Rodolia fumida and Sumniusrenardi are important predators in controlling the nymphs. The entomogenousfungus Beauveria bassiana is found to be an effective bio agent in controlling the nymphs of the mealy bug.
Fruit Fly
Control
Chemical : The adult fruit flies
can be controlled by bait sprays
of carbaryl (0.2%) + protein hydrolysate
(0.1%) or molasses starting at pre-
oviposition stage (first week of April),
repeated once after 21 days. Another method to control these flies is tohang traps containing a 100 ml water emulsion of methyl eugenol(0.1%) + Malathion (0.1%) during fruiting (April to June). About 10such traps are sufficient for one hectare of orchard.
Red rust
Symptoms
• Rusty spots appear on leaves, initially as circular, slightly elevated, coalesce to form irregular spots.
• The spores mature fall off and leave cream to white valvettexture on the surface of the leaves
Control
Bordeaux mixture (1%), or Copper oxychloride 0.25%
• Shoot borer
• Bark-eating
caterpillar
• Stem borer
• Shoot gall psylla
• Leaf webber
• Stone weevil
Physiological Disorders
Malformation is widely prevalent in northern India, particularly in the states of Punjab, Delhi and western U.P. where more than 50% of the trees suffer from this malady.
Causes: The complexity of the disorder is attributed cultural practices, nutritional, to many factors like, mites, fungal, viral, hormonal imbalance etc.
Symptoms
Three types of symptoms: bunchy top phase, floral malformation and vegetative malformation.
In bunchy top phase in nursery bunching of thickened small shoots, bearing small
rudimentally leaves. Shoots remain short and stunted giving a bunchy top appearance.
In vegetative malformation, excessive vegetative branches of limited growth in seedlings.
They are swollen with short internodes forming bunches of various size and the top of the seedlings shows bunchy top appearance.
In malformation of inflorescence remain unproductive and are characterised by a compact
mass of male flowers, greenish in colour and stunted in growth.
Secondary branches are transformed into number of small leaves giving a witches broom appearance.
Mango malformation
Control measures
The exact cause and control of the malady is yet to be established.
Use of disease free planting material.
Diseased plants should be destroyed.
Incidence reduced by spraying 100-200ppm NAA during October.
Pruning of diseased parts with the basal 15-20 cm apparently healthy portions.
Followed by the spraying of Carbendazim (0.1%).
Alternate Bearing or Biennial Bearing
• Factors:
– Environmental factors
– Age and Size of shoot
– Crop load
– Hormonal control
– C : N ratio
– Varietal influence
Refers to heavy fruiting in one years (ON YEAR) followed by less or no fruitingin the following year (OFF YEAR).
Control Measures:
Deblossming and thinning of fruit
Smuding
Use of Plant growth regulator
Pruning
Application of KNO3
Growing regular bearing varieties
Fruit Drop
Despite high fruit set initially, the ultimate retention is quite low in mango. The intensity of fruit drop, varies from variety to variety.
The fruit drop is more or less a continuous process and can be classified into three groups : (i) Pinhead drop, (ii) Post-setting drop and (iii) May-month drop.
The fruit drop in first two groups are insignificant compared to the third group which affects the final yield significantly and needs more attention.
Major factors: Embryo abortion, climatic factors, disturbed water relation, lack of nutrition, disease, pest and hormonal imbalances.
Control: The foliar application of Alary (B-nine) @ 100 ppm or NAA 20 ppmat pea stage.
Among the commercially grown varieties, Langra is more susceptible to drop
while Dashehari is the least.
Maturity
Fruits generally require 95 to 115 days mature after flowering
Building of shoulders and a slight depression near the stalk ‘end’
Colour changes from dark green to pale green
Red blush develop on the fruits shoulders
When one or two ripe fruits fall from the plant naturally
When the specific gravity of fruits ranges between 1.01 to 2.0
Flesh Firmness vs Ripeness Stage of Mangos
Ripeness stage Flesh firmness (lb-force with 5/16 inch tip
penetrometer)
Notes
Mature-green >14 Treat with ethylene for 48 hours
Partially-ripe 10-14 Treat with ethylene for 24 hours
Firm-ripe 6-10 Best stage to send to retail stores
Soft-ripe 2-6 Best stage for eating
Over-ripe <2 Good for juice
Harvesting
The harvesting in mango should be done in the morning hours and fruits should be collected in plastic trays and kept in shades.
The fruits should not be allowed to fall on the ground as the injured fruits cause spoilage to other healthy fruits during packaging and storage.
Fruits harvested with 8-10 mm long stalks appear better on ripening as undesired spots on skin caused by sap burn are prevented.
Fruits harvested by stick are injured / bruised due to impact resulting in decay, poor quality and attract low price. Traditional methods consume a lot of energy.
To overcome these problems, a simple, low cost and portable mango harvesting device has been designed and developed at CISH, Lucknow.
This saves time and protects fruits from mechanical damage due to impact.
YIELD: In mango yield is varies with the variety. The average mango yield is 8 tonnes/hec. Which varies with the region. Andhra and Bihar are highly productive with this respect. HDP increase yield of mango.
Grading
If the fruits are graded according to their size, weight, colour and maturity, both the producer and consumer are benefited.
It has been observed that bigger size fruits take 2-4 days more time in ripening than smaller ones .
Hence, packaging of smaller fruits with larger ones should be avoided to achieve uniform ripening.
Immature, overripe, damaged and diseased fruits should be discarded.
The export quality mangoes are categorised into three grades according to the fruit weight viz., Category-I (200-250 g), Category-II (251-300 g) and Category-III (300-350 g).
Storage
• The mature green fruits can be kept at room temperature for about 4-10 days depending upon the variety.
• Shelf life of fruits could be extended by pre-cooling, chemical treatments, low temperature, etc.
• The harvested fruits are pre-cooled to 10-12oC and then stored at an appropriate temperature.
• The fruits could be stored for 3-4 weeks in good condition at low temperature.
• The problem of chilling injury at low temperature can be overcome by keeping the fruits in 0.5% ventilated polythene bags.
• The fruits of Dashehari, Mallika and Amrapali should be stored at 12oC, Langra at 14oC and Chausa at 8oC with 85-90% RH.
