Sustaining by diversifying The Issue in addition to RWC Rationale of ICRISAT’s Involvement Legume-based technologies as long as Rice in addition to Wheat Production Systems Successful Technologies

Cummings, Benner, Contributing Writer has reference to this Academic Journal, PHwiki organized this Journal Sustaining by diversifying Legume-based technologies as long as Rice-Wheat production systems in Indo-Gangetic Plain (IGP) Suresh P in addition to e Regional Project Coordinator Crop Diversification Project: ICRISAT The Issue in addition to RWC Continuous cereals cultivation apparently associated with: Yield stagnation Nutrient in addition to water imbalance Increased pest in addition to disease incidence Rationale of ICRISAT’s Involvement Inclusion of legumes make the cereal-dominated system more sustainable Legumes enhance soil fertility Can break insect-pest in addition to disease cycles in cereals Can diversify farm income Add protein to complement cereals Quarter-century expertise relating to important legumes: chickpea, pigeonpea in addition to legumes.

Legume-based technologies as long as Rice in addition to Wheat Production Systems Objectives Quantify the scope of legumes in RWCS Develop technological options as long as overcoming major biotic in addition to abiotic constraints Evaluate improved technologies in farmers’ fields Assess adoption in addition to quantify the impact Successful Technologies System characterization Integrated soil, water in addition to nutrient management (ISWNM) Integrated pest, disease in addition to nematode management (IPM) Sustainable l in addition to -use systems System Characterization GIS analysis of cropping systems Legumes in rice in addition to wheat cropping systems of the IGP: constraints in addition to opportunities. GIS application in cropping system analysis – case studies in Asia.

Soil in addition to Water Management Using GIS with WATBAL: Soil water availability in addition to length of growing season as long as IGP of India, Nepal in addition to Bangladesh were mapped

Nutrient Management Following a nutrient model (NUTMOD), rationalize fertilizer use was established on cropping systems: Bangladesh – rice-chickpea India – mungbean-rice-wheat in addition to pigeonpea-wheat Nepal – mungbean-rice-wheat Pakistan – mungbean-wheat Chickpea flower drop Normal Deficient Doubling yield with Boron Boron deficiency a major yield constraint to chickpea in addition to lentil in parts of IGP One kg B per ha increased grain yield in chickpea by 42% to 92% Technology is now ready as long as large scale application.

Integrated Pest Management Helicoverpa pod borer Sowing in May of the extra-short duration genotype, ICPL 88039 – developed by ICRISAT in addition to its partners – which generally escapes Helicoverpa damage Judicious insecticide application Why pigeonpea as long as RWS sustainability Known to improve soil fertility Grows largely rainfed. Fixes its own nitrogen Contributes organic matter in the as long as m of senesced leaves, root residue, in addition to releases P from fixed as long as ms. Its area is declining in the IGP because: -Low yield vis-à-vis rice -Greater risks -Longer duration of cultivars available with farmers ESD Pigeonpea – wheat rotation Extra-short-duration (ESD) genotypes have been developed that allow: pigeonpea-wheat rotation. ESD pigeonpea yield 3 t ha-1 Up to about 1 t ha-1 extra yield of wheat could be harvested when it followed ESD pigeonpea

ESD pigeonpea as long as cultivation in rotation with wheat ICPL 88039 as long as cultivation in rotation with wheat Wheat yield after rice, SD pigeonpea in addition to ESD pigeonpea at Sonepat, Haryana (1997-99) IPM of Legumes (Chickpea) The five Bs: Boron deficiency Botrytis gray mold (BGM) Bhilt (Wilt) Borer (Pod borer) Bruchids (storage pests) Blue Bull

Components of IPM of legumes (Chickpea) HPR : BGM tolerant variety (Avarodhi) Agronomical: Improved cultural practices Fungicides: Weather/Need-based application Insecticides: Need-based application IPM – A Success Story: Rehabilitation of chickpea in Nepal in addition to Bangladesh Farmers Participatory IPM Farmers Participatory IPM

Adoption in addition to Impact of chickpea in Nepal Integrated Pest Management Sustainable L in addition to Use System The Barind Success Story Chickpea identified as a second crop on residual moisture Low labour, low input technology Farmers are now getting second crop where there was only one Technique extended to Nepal

Sustainable L in addition to Use System Seed Priming In Barind, Bangladesh Plant st in addition to improved by 22% Grain yield by 47% Stover yield by 31% Sustainable L in addition to Use System Residual Effect Long-term experiments conducted with PAU showed: High nitrogen fixing chickpea line out-yielded its normal nodulating parent A book on residual effects of legumes in rice-wheat cropping system of the IGP published. Sustainable L in addition to Use System Rice Straw Compost Application of 2 t/ha compost prepared from rice-straw (normally burnt by farmers) along with the recommended levels of fertilizers produced 4-9% greater yield of rice + wheat Technology is ready as long as up-scaling

New Emerging Researchable Issues if any Carry over of pests in system perspective Define sustainability indicators of RWC Scale-up of IPM in legumes in IGP Scale-up of seed priming technology Modelling to identify new cropping systems In situ decomposition of crop residue Conclusions Greater inclusion of legumes into RWCS of IGP, the crop diversification project efficiently links ICRISAT to RWC in addition to partners The project is pumping new life into the cereal-based systems in addition to bring new hope to the people of IGP. Seeds as long as Next Crop
