The increase in emission of greenhouse gases (GHGs) due to anthropogenic perturbation in both the agricultural and natural eco-systems are degrading the environmental quality. Conventional tillage (CT) and residue burning/removal exacerbates the land degradation and GHG emission, and the impacts are much more in the upland ecosystem than valley lands. Therefore, the aim of the present study was to evaluate the energy budget, and carbon footprint (CF) of no-till (NT) and mulches under the upland rice (Oryza sativa)–mustard (Brassica campestris var. toria) cropping system over CT based system to develop a clean production technology for improving the environmental quality and conservingnatural resources. The novelty of the study is that integrated effect of NT, diverse mulches and cropping system effect has been considered together as a conservation measure for sustainable and clean agricultural …
