Increasing crop productivity while reducing greenhouse gas emissions through resource conservation technologies in rice-wheat-mungbean cropping system

Resource conserving technologies (RCTs) enhance input use efficiency and provide immediate identifiable economic benefits like reduced production costs, savings in water, fuel and labor requirements and timely establishment of crops resulting in improved productivity. They can also reduce GHG emissions with less global warming impact (Aggarwal et.al. 2002). The CO2 mitigation strategy for intensive rice-wheat-mungbean cropping systems has not been well studied. Crop residue management, tillage type and N fertilization strategies are likely factors to increase crop productivity and alter fuel consumption. The objective of this trial is to assess the potential productivity and reduction in GHG emissions by using RCT in rice-wheat system
