Abstract
In Indo-Gangetic Plains (IGP) zone of India, rice-wheat rotation is maily followed. This has led to practices like tillage, water, energy and crop residue burning in conventional management systems of RW rotation which contributed significantly in greenhouse gas (GHG) emission/environmental pollution. Climate smart agricultural practices (CSAPs) are being deployed for adapting to climatic risks while enhancing productivity and quality of environment in the prevailing RW rotation of IGP. A farm research trial was conducted to evaluate GHG mitigation potential of various CSAPs. Six management treatment included; Farmer’s practice/business as usual (FP); Partial improved FP(PI-FP); Improved FP(I-FP); Climate smart agriculture practices with low intensity portfolios (CSAP-L); CSAP with medium intensity portfolios(CSAP-M); CSAP with high intensity portfolios(CSAP-H). The global warming potential (GWP) of RW rotation was highest under FP and least under CSAP-H. Estimated GWP on overall basis was 37% lower than that under FP. Also, on an average, 6% higher RW system yield was revealed with CSAPs compared to FP (11.96 Mg/ha). About 60% lower emission of green house gas emission was recorded in climate smart agriculture practices which was lower than farmer practices. Our results indicate that the validated CSAPs have potential to reduce environmental footprints of the RW rotation with similar or higher productivity.
