Fertilizer managementFertilizer management The time and placement of fertilizer is another area where

significant progress was made. It was demonstrated that 120 kg nitrogen, 60 kg phosphorus

and 30 kg potash per hectare were required for optimum productivity.

The N was to be applied in two split doses of 60 kg as basal and the remaining 60 kg at first irrigation and full phosphorus and potash to be applied as basal.

Recently, the new wheat varieties have responded up to 180 kg N/ha with optima dose around 150 kg/ha.

In the Indo-Gangetic plains, application of zinc @ 25kg/ha in rice-wheat system was found to increase the yield substantially.

Recently, the use of sulphur has been found beneficial for enhancing the productivity as well as the grain protein content of wheat.

Response to Mn (pockets in the Indo-Gangetic plains) and boron (eastern and far eastern region) has also been realized.

Nutrient management The work conducted under the All India Coordinated Research Project

on Micronutrient in Crops and Soils, has shown wide spread deficiency of zinc in soils in India.

At the national level, the deficiency level in micro nutrients is Zn: 46 %, B: 17 %, Mo: 12 %, Fe: 11 % and Cu: 5%.

The deficiency of sulphur has also been reported across a wide range of soils (38%).

The yield response to sulphur has been obtained in more than 40 crops including cereal, millets, oilseeds and pulses etc. To realize the potential yield, strategies may include

Site specific nutrient management for targeted yields Integration of crop residues, bio fertilizers etc with inorganic

fertilization Tillage techniques like FIRBS for increasing nutrient use efficiencies Remote sensing for efficient Nutrient management With intensive agriculture, deficiency of essential nutrients has also

become wide spread.

• timely sown conditions : 100 kg/ha

• late and rainfed conditions : 125 Kg/ha (increased by 25%)

Seed Rate:

The average temperature at sowing : around 23 - 10C

Timely sown : 5th to11th Nov. ; Late sown : 10th to 16th Dec.

• In lines using fertilizers-cum-seed drills and discourage broadcast sowing

• Row to row spacing : 23cm (timely sown) and 18 cm (late sown)

Seeding depth : around 4-5 cm.• Zero till and rotary till drill can be used for

economising cost of cultivation.

Sowing methods:

• application & conservation methods ,their water use efficiency ,water requirement of crop, critical stages for irrigation and probable losses if not applied : Adequate soil moisture is required for normal development of the wheat plant at all the stages of growth. The crow root initiation stage and heading stage are crucial stages when plant suffers most due to moisture stress .

Water Management

• Weeds emerge with the emerging crop seedlings and if not controlled in the early stages of crop growth these may cause

• reduction in yield varying from 10-40 % depending upon the intensity and kind of weeds present in an area.

When field is generallyinfested from both dicot and monocot weeds . The major dicot weeds are Chenopodium album, Fumaria purviflora,

Cirsium arvense• Anagalis arvensis , Melilotus alba, and Melilotus indica,Vicia sativa, ,

lathyrus spp.,etc., Monocot weeds include: Phalaris minor,• Avena fatua, , Polypogon monspllensis, Cyperus rotundus and Cynodon

dactylon.

. Weed Management

• 1st irrigation: The 1st irrigation to the standing crop should be given 20-25 DAS(CRI stage)

Different irrigation stages

• 2nd Irrigation: At tillering stage, within 40-45 DAS.

• 3rd irrigation: At late jointing stage , within 70-75 DAS.

• 4th irrigation: At flowering stage ,within 90-95 DAS. Irrigation at this stage is also important because during this period plants

• suffer most from soil moisture deficiency . The grain number and grain size are reduced considerable.

• 5th irrigation: At dough stage, within 110-115 DAS.

Continuation

1. Where only one irrigation is possible, give it at crown root initiation (CRI) stage (20-25 DAS).2. Where two irrigations are available, 1st irrigation should be given at CRI stage and 2nd at flowering stage.3. Where three irrigations are a possible, 1st irrigation should be given at CRI stage and 2nd at late jointing (boot) and 3rdat milking stage.

At present, nearly 95% of the area sown to wheatin Punjab and Haryana has assured irrigation.

The agronomy group has demonstrated that irrigating wheat at crown root initiationstage (CRI) which is approximately 21days after sowing is most crucial. If water is available subsequently, it was advised to utilize theirrigation during tillering and at flowering stages. Using the FIRB technology, it had been demonstrated that water saving to the extentof about 30 percent could be achieved for wheat cultivation.

Pre-emergence• As pre-emergence, only Stomp 30EC

(Pendimethalin) is available which can be applied @ 3300 ml/ha (1000 g a.i/ha) at 0-3 days after sowing in 500 liters of water /ha. Care must be taken to have fine tilth for better performance of pendimethalin. It controls both grasses and broadleaved weeds.

• The herbicides that are to be applied as post emergence after first irrigation at 30-35 days of sowing or 2-3 leaf stage of Phalaris minor

Post-emergence

• Generally weeds are eradicated with the help of hoe, khurpi etc.

• However, now-a-days it has become difficult due to labour

• cost and unavailability of labour.• Now a number of chemical weedicides are

available that control the weeds in wheat rather Effectively.

• IPM in wheat specially to manage the diseases like Karnal Bunt, Powdery Mildew, loose smut and insects like foliar & root aphids

• Managing new emerging threats• stem rust (Ug99),• leaf rust (77-5, 77-10, 104-2)• stripe rust (78S84, 46S119)• Foliar blight• Fusarium head blight (FHB)s, termites, root

nematodes

• Broad and narrow leaved

Abiotic stresses– Drought – Heat

• Early as well as terminal – Suppressive soils/Soil

health • Salinity, alkalinity• Nutrient deficient soils• Waterlogging

Yield plateau in north western parts

Other constraints– Availability of essential inputs for

timely sowing• Improved seed (More problem in J&K, HP,

Rajasthan)• Fertilizer availability (its availability in required

quantity and at initial and growth stage, is critical.

• Irrigation water (Timely availability of optimum quantity)

• Use of Farm machinery – Infrastructure

• Roads• Storage• Market

– Extension facilities• Farmers need more awareness of new

improved varieties and production technologies• Faster extension activities

Major Issues : Wheat ImprovementBreaking yield barriers

• Replacement of yellow rust susceptible varieties PBW 343, PBW 502 and HD 2687 with DBW 17, PBW 550 & WH 542.

• Under late sown conditions (late basmati-wheat, potato-wheat and sugarcane-wheat) – PBW 373 should be replaced with DBW 16, WH 1021, PBW 590,

Raj 3765 as PBW 373 has become susceptible to brown rust

Varietal replacement

Eastern UP, Bihar• Under TSI conditions, varieties like HD 2733, HD 2824, PBW 443, HUW 468 needs to be

promoted and breeder seed production of varieties like UP 262 and HUW 234 should be curtailed.

• Under LSI conditions, varieties like DBW 14, NW 2036, HW 2045, NW 1014, K 8962 and HD 2643 should be promoted.

Madhya Pradesh, Chhatisgarh, Gujarat and Kota region• Lok 1 is still a reigning variety which needs replacement. • Under TSI, GW 322, GW 273 while under LSI cnditions HD 2864, MP 4010, DL 788-2

requires promotion.• For durums HI 8498 and HI 8381 are the best varieties for the area.• As these states have a sizeable area under rainfed or limited irrigation

– HI 1531, HI 1500 of bread wheat and HD 4672 and HD 8627 for durum should be promoted while WH 147 should be phased out.

Varietal replacement

Maharashtra, Karnataka• For TSI conditions GW 322, RAJ 4037, NIAW 917, DWR 162 and MACS 2496 for bread

wheat and MACS 2846 for durum• LSI sown conditions: PBW 533, HD 2833 and NIAW 34• Rainfed conditions: HD 2781, K 9644 for bread wheat and AKDW 2997-16 for durum.

Non-traditional wheat growing area - Jharkhand, Orissa, West Bengal and plains of N.E. States; some parts of the plains of Tamil Nadu and Andhra Pradesh

• Due to early onset of rains and to avoid pre-harvest sprouting, these areas require short duration wheat varieties like DBW 14, NW 2036, HW 2045. variety DBW 14 has shown promise in Jharkhand and Assam

• For plains of Tamil Nadu and Andhra Pradesh – a state release variety, CoW(W)-1 has been showing promise.

Varietal replacement

Plant Protection Measures

• Replace with new resistant varieties for rust resistance

• Spray the crop (susceptible varieties only) with propiconazole 25 EC (Tilt 25 EC) @ 0.1% at yellow rust initiation. This spray will also help in control of powdery mildew and Karnal bunt diseases.

• Seed treatment with T. viride @ 4 g / Kg seed in combination with carboxin 75 WP (Vitavax 75 WP) @ 1.25 g / Kg seed or tebuconazole 2 DS (Raxil 2 DS) @ 1.0 g / Kg seed.

For managing cereal cyst nematode (CCN) in dry belt of northern RajasthanCCN resistant wheat variety - Raj MR-1 Barley varieties - RD 2035 and RD 2052.

Resource ManagementSowing timeThe average temperature at sowing : around 23±10C Timely sown : 5th to11th Nov. ; Late sown : 10th to 16th Dec.

Seed Rate: timely sown conditions : 100 kg/ha late and rainfed conditions : 125 Kg/ha (increased by 25%)

Sowing methods: In lines using fertilizers-cum-seed drills and discourage broadcast sowingRow to row spacing : 23cm (timely sown) and 18 cm (late sown) Seeding depth : around 4-5 cm. Zero till and rotary till drill can be used for economising cost of cultivation. Use of rotary tiller followed by broadcasting of seed and fertilizer causes the lodging problem leading to reduced yields. Thus, Rotary tiller having drilling mechanism for seed and fertilizer should only be used.

Nutrient management • Use of recommended doses of the fertilizers (NPK)• Nitrogen use efficiency is more when fertilizer is placed by drill • 1/3rd N application at sowing and 2/3rd at first node stage. • Supplementing inorganic fertilization (NPK) with Zn and FYM increases

the wheat yield.• Application of K is necessary. • Micronutrient deficiency appears under light soils under intensive

cropping especially in rice-wheat cropping system. • In sulfur deficient soils, SSP, Cosavet -90 WDG (10 kg/ha) or

gypsum (250 kg/ha) can be applied. : increasing yield and protein content.

• Zinc sulphate should be applied @ 25kg/ha once in rice-wheat system or 2-3 foliar spray of 0.5% zinc sulphate (21% zinc) at 15DI

• In Mn deficient soil, spray 0.5% managanese sulphate solution 2-4 days before first irrigation and two to three sprays afterwards at weekly intervals on clear sunny day.

Sulfosulfuron / pendimethalin both grassy and non-grassy weeds

Clodinafop / fenoxaprop / pinoxaden specific to grasses.

Sulfosulfuron + metsulfuron or isoproturon +2,4-D / metsulfuron Complex weed flora

Grass herbicides (clodinafop, fenoxaprop, pinoxaden) should not be tank mixed with either 2,4-D or metsulfuron and to avoid antagonism the grass and broad-leaved herbicides should be applied sequentially.

Pinoxaden can also be used in barley for grassy weed control.

Weed management

Improving soil health – RWCS: high pressure on land resulting in decline in total factor productivity. – Addition of organic matter to soil through

green manuring, crop residue recycling, balanced fertilisation and integrated nutrient management.

– Diversification/intensification of RWCS by including pulse crops – Minimum soil disturbance with residue retention at the soil surface

help in water conservation as well as slow decomposition and thus building up the organic carbon status of the soil – solution to crop residue burning

– Correction of micro-nutrient deficiency –Zn, S, Mn – Integrated management for weed control especially Phalaris minor

Short term strategies for states of Punjab and Haryana

•Availability of essential inputs for timely sowing – the most important factor– Improved seed (More problem in Eastern UP, Bihar –problem in 60% wheat growing

area as seed replacement is very low) – • a bouquet of latest and improved varieties for different production conditions are

available – need more breeder seed of recent released varieties

– Fertilizer - availability (its availability in required quantity and at initial and growth stage, is critical) and its balanced use

– Irrigation water (Timely availability is important)

– Farm machinery (Mechanization is on a lower scale in northeastern, central and peninsular parts)

•Infrastructure development – roads, storage and market

Short term strategies for other states

• Breaking yield barriers

– Developing wheat hybrids through CMS approach

– Broadening of genetic base of varieties • Through use of winter x spring hybridization• Use of Chinese germplasm• Use of wild species for biotic and abiotic stresses

– Biotechnological interventions• Gene pyramiding• Marker aided selection for biotic, abiotic and quality traits• Structural and functions genomics

Long-term strategies for increasing wheat production

• Sustainability of rice-wheat system through – Resource conservation technologies– Refinement of machines– Developing tillage specific varieties– Diversification/intensification– Water and nutrient use efficiency– Tackling weeds and pests under new tillage– Residue management– Land leveling through laser leveler

• Improving soil health– Increasing carbon content– Correction of micro-nutrient deficiencies/toxicity– Balance use of fertlizers

• Organic farming

Long-term strategies for increasing wheat production

• Use of agriculturally important micro-organisms– Bio-agents– Biological control of pests and diseases

• Integrated pest management• Survey and surveillance for new races• Combating rusts through durable resistance

– New race of yellow rust – 78S84– New race of black rust – Ug99

• Creating effective resistance against leaf blight and Karnal bunt• Newly emerging problems of termites and aphids• Wheat quality improvement

– Developing product specific varieties– Increasing protein content, sedimentation value and grain hardness to match international standards– Improving beta carotene and protein content and semolina recovery in durums– Biofortification– Collaboration between research institutions and wheat based industry
