摘要：

A field experiment was conducted during 1993-96 at Bilaspur to study the energy requirement, water use and economics of seven different rice-based cropping systems. Among the cropping sequences tried, the energy input and output were maximum in rice-rice. However, energy output of major products was maximum in rice-peanut system. Energy use efficiency was maximum with rice-chickpea followed by rice-wheat. Rice-chickpea system recorded the highest water use efficiency followed by rice-sunflower, but the total amount of water used was more in rice-rice system. Cultivation cost was maximum with rice-rice system (Rs 25398/ha) while the net return was more or less same in rice-rice, rice-wheat and rice-peanut cropping systems.
