Welcome to National Innovations on Climate Resilient Agriculture, Indian Agricultural Research Institute

Technical programme in brief including methodology and activity milestones in 2015-16

The project will focus on irrigated area of the country (Fig. 1). Initially (1st and 2nd year) the work will be carried out in the Indo-Gangetic plains (IGP), which has the largest area under irrigation in the country. Later on other irrigated areas will be covered.


Objective 1

 

Phenotyping, physiological evaluation and genetic improvement of irrigated crops (rice, wheat, chickpea) for heat and drought stresses.

• Physiological and biochemical response of rice, wheat and chick pea to temperature and moisture stresses.
• Functional and proteomic characterization of heat responsive genes and proteins in wheat and rice.
• Phenotyping and marker based genotyping for moisture and heat stress tolerance in wheat.
• Marker assisted improvement of drought and heat tolerance in basmati and non-basmati rice varieties.
• Phenotyping of reference set germplasm to identify donors for heat tolerance in rice and cold tolerance in chickpea.
• Evaluation of marker based improved/ selected lines for homozygosity and homogeneity.
• QTLs known for drought and heat tolerance are being introgressed in high-yielding lines. The selected lines will be advanced for obtaining homozygosity during crop-season.
• Phenotypic evaluation of RIL population for heat tolerance and other phenotypic traits and molecular marker analysis of the RIL population.
• Screening of different wheat lines from core subset for thermotolerance using different biochemical parameters.

Objective 2

 

Monitoring of GHG emissions through flux towers/field measurement in irrigated rice-wheat production system in the IGP (New Delhi) and rice-rice system in south-east peninsula (Aduthurai).

• Measuring GHGs emission using flux tower in rice-wheat eco-system in the Indo-Gangetic plains and closed-chamber technique in rice-rice system in south-east peninsula (Aduthurai).
• Mitigating GHGs emissions from rice fields through microbial interventions.
• Mitigating GHGs emissions from rice-wheat eco-systems through conservation agriculture and crop diversification

Objective 3

 

Adaptation and mitigation through improved crop management, enhanced water productivity and nutrient use efficiency; and carbon and nutrient budgeting in rice-wheat system.

• Assessment of surface and groundwater availability and crop-water demand at field and regional scales under current and climate change scenarios.
• Quantification of C, N and energy budget under climate change scenarios and assessment of C sequestration potential at various agro-ecological zones.
• Development of microbe-based technology for tolerance to climatic stresses.
• Development of drought indices and monitoring system at various agro-ecological zones.
• Enhancing water and nutrient use efficiency through conservation agriculture.
• Field experiments for enhanced water and nutrient use efficiency in rice-wheat cropping systems using modern irrigation methods (drip irrigation and fertigation).
• Studying the effect of conservation agricultural practices on carbon and nitrogen enrichment in soil of Mumtajpur village.
• Initiation of long-term carbon mineralization experiment on biochar stability in soils with varying carbon level.
• Assessment of long-term effect of various residue management (crop residue incorporation, crop residue burning, crop residue removal) including biochar on C sequestration and soil health in rice-wheat, maize-wheat and pearl millet-wheat cropping system.
• Quantification of C and N budget of the Mumtajpur village.
• Evaluation of selected isolates their ability to assist in establishment of wheat and direct seeded rice at high temperature and moisture.

Objective 4

 

Strengthening real-time data capture on crop health through Satellite Data Reception System and integrate the output to agro-advisories.

• Real-time monitoring of crop conditions at regional scale.
• Regular generation of meteorological and crop health parameters from satellite images.
• Aggregation of parameters at district levels for generation and analysis of meteorological and crop condition for 580 districts of India.
• Development of a web interface for visualization and dissemination of district level health indicators.


Objective 5

 

Integrated crop modelling for wheat and rice for impact assessment and indentifying adaptation strategies at regional level for near and long-term downscaled scenario.

• Integrated modelling of climate change impacts and development of adaptation strategies.
• Developing pest simulation model for forewarning and coupling it with InfoCrop.
• Simulation of disease distribution (through mapping probable infection) of diseases in rice, wheat and chickpea.
• Simulation of yield loss in rice, chickpea and wheat linking crop growth model.
• Formulation of empirical pest-weather relationships for rice and wheat pests.
• Predict the impact of climate change on water resources availability and crop production in different sub basins of IGP.


Objective 6
