This study compares thirteen rice-based cropping systems in the coastal part of West Bengal, India terms productivity, profitability, energetics, and emissions. Information on crop management practices these was collected 60 farms through a questionnaire survey. Rice-bitter gourd system observed to have highest yield (49.88 ± 4.34 tha−1yr−1) followed by rice-potato-ridge (37.78 2.77 rice-potato-pumpkin (36.84 2.04 systems. The rice-bitter also recorded benefit:cost ratio (3.92 0.061). lowest economics were rice-fallow-fallow system. Rice-sunflower specific energy (2.54 0.102 MJkg−1), rice-rice (2.14 0.174 MJkg−1) (1.91 0.327 systems, being (0.52 0.290 rice-pointed 0.373 Yield-scaled GHGs (YSGHG) emission (1.265 0.29 t CO2eqt−1 yield) for rice-vegetable To estimate uncertainty YSGHG across different under study, Monte-Carlo Simulation performed.
