Croppingsystems .rice-cowpea,rice-groundnut,rice-brinjalandrice-sweetcornwere testedfortheirproductionpotential,economicfeasibility,nutrientbalanceandenergybudgetingalongwith rice-fallowascontrol.
The data indicated significantly higher rice equivalent yield (23.5 t ha ) with rice-sweet corn followed by rice-brinjal (14.1 t ha ) as compared to a predominant rice-fallow system of the region (5.50tha ).Higher potential usableresiduewasalsofoundhigherwithrice-sweetcornsystem(36.9tha ). Results of the energy ratio (46.5), specific energy (0.65 MJ kg ) and energy productivity (1.52 kg MJ ) indicate that the rice-sweet corn is most energy efficient system among all the evaluated systems.
