摘要

Conventional agro-techniques of agricultural production are expensive and energy-intensive, resulting in greater greenhouse gas (GHG) emissions, carbon footprints and poorer water productivity. Conservation agriculture (CA) practises and efficient irrigation methods lead to more sustainable and environmentally sound crop production under intensive cropping systems. Hence, four-year (2018-19 to 2021-22) trials were conducted in split plot designs for maize and split-split plot designs for chickpea using three replications. The main plot of the split-plot design comprised of three residue levels (30, 60, and 100%), while the sub-plot treatments included three tillage methods viz., conventional tillage (CT), reduced tillage (RT) and zero tillage (ZT). On the other hand, the split-split plot design had three tillage methods (ZT, RT, and CT) as sub-sub plots, three residue levels (30, 60, and 100%) as sub-plots and two irrigation methods (sprinkler and furrow) as the main plots. ZT with sprinkler irrigation and 100% residue retention increased system productivity by 12 compared to CT. In contrast, carbon footprint (CF) for RT and ZT along with furrow irrigation and 30% residue loads, decreased by 15% and 22%, respectively as compared to CT.
