                                              Mitigation of Climate Change through Conservation Agriculture in Rainfed Regions of India 

   

           

            An experiment was conducted with different in situ conservation practices, tillage practices, and mulch treatments to identify the climate resilient resource conservation practices. GHG emissions were recorded indifferent treatments with closed vented static chamber.The CO2 fluxes in different treatments ranged from 0.87 to 15.58 kg C ha-1hr-1. It was observed that when there is a continuous rainfall of high intensity, the CO2 emissions were lower in conventional tillage as compared to zero tillage. N2O fluxes in conventional and reduced tillage were on par with each other but these two treatments recorded 20% higher fluxes as compared to zero tillage. Higher CO2 and N2O fluxes were observed in 10 cm anchored residue height but in case of 30 cm harvest height, CH4 absorption was observed.  Conservation furrow and paired row conservation furrow recorded 15 and 16 % higher yields respectively as compared to flat sowing without conservation furrow. Mulch treatment (growing of daincha crop between pigeonpea rows and application of daincha at 45 DAS as mulch in pigeonpea) recorded higher yields as compared to no mulch treatment. Among the nutrient management application of RDF, RDF+FYM recorded 20 and 12% higher pigeonpea yields as compared to control. Rotavator, cultivator and Disc plough + harrow recorded higher GHG emissions and GWP, whereas animal drawn implements recorded lower emissions and energy.
