To investigate the energy input, energy output, output-input ratio, specific energy requirement and cost economics of different rice based cropping system on IGKV farm. Four major crops like rice, wheat, chickpea and linseed were selected. The energy consumption of the various operations in each crop production has been recorded. Total energy input and output of different cropping systems were estimated by using the standard energy equivalents. The rice-wheat cropping system recorded the highest energy input 29214.73MJ ha−1, which was closely followed by rice-linseed system 22748.5MJ ha1. The highest total energy output was obtained from rice-wheat 245305.9 MJ ha−1, followed by ricechickpea 217753.1 MJ ha−1and rice-linseed 199905.9 MJ ha−1 respectively. Among the different cropping system, the highest energy output-input ratio of 10.73 was obtained from rice-chickpea cropping system followed by rice-linseed 8.78 and rice-wheat 8.39 respectively. The specific energy required was found lowest in rice-chickpea cropping system having value 2.81 MJ kg−1 followed by rice-wheat and rice-linseed 3.54, and 3.64 MJ kg−1 respectively. Under the different cropping systems the lowest input cost was found Rs 43005.28 ha−1 in rice-wheat cropping system followed by, rice–linseed and rice-chickpea. The maximum net return Rs.86575.8 ha−1 was found under rice-chickpea followed by rice-wheat and ricelinseed Rs.70477.8 and 63523 ha−1 respectively. The highest benefit to cost ratio of 1.97 was obtained in rice-chickpea cropping system followed by rice-wheat 1.64 and rice-linseed 1.5 respectively.
