Abstract: The field experiment was conducted at the Agricultural Research Farm, Banaras Hindu University, Varanasi (U. P.) in two consecutive years of 2016-17 and 2017-18 to study the energetic of winter crops under rice based cropping sequences in irrigated condition of eastern Uttar Pradesh. Results revealed that energy output, net energy and energy intensity was found significantly higher with wheat grown in rice-wheat-cowpea fodder sequence (S₄) but it was remained comparable with wheat grown in rice-wheat-green gram sequence (S₂) and rice-wheat sequence (S₁) during first year, however during second year it was found at par only with rice-wheat-green gram sequence (S₂). The lowest energy output, net energy and energy intensity recorded in cabbage grown in rice-cabbage-cowpea fodder sequence (S₁₀) were mainly because of its having lowest energy equivalent in economic produce. Energy output: input ratio was significantly highest in mustard grown in rice-mustard-sudan grass fodder sequence (S₈) but it was found at par with mustard grown in rice-mustard-cowpea fodder sequence (S₉) during first year and vice-versa during second year. The energy productivity was highest in rice-cabbage-cowpea fodder sequence (S₁₀), proved distinct superiority over rest of the winter crop grown in different sequences. Nevertheless, highest specific energy was noted in berseem in rice-berseem-maize fodder sequence (S₆) remained at par with berseem grown in rice-berseem-cowpea fodder sequence (S₇) during both the years of investigation.
