This study evaluated energy requirements, gross energy output and energetic indices under different rice establishment methods and nitrogen management practices under rice-rice cropping system. The energy input in normal transplanting (M1) was 3.85 and 3.90 per cent higher than mechanized SRI (M2) during 2017 and 2018, respectively. There was no significant difference in gross energy output, net energy productivity, energy use efficiency, net energy returns and specific energy requirement due to establishment methods. Mechanized SRI recorded significantly higher energy intensity in economic terms (3.13 and 2.93 MJ ₹-1) as compared to normal transplanting (2.71 and 2.56 MJ ₹-1) during 2017 and 2018, respectively. Application of nitrogen as per recommendation of Nutrient Expert with NCU (N1) recorded higher energy input. Application of nitrogen as per recommendation of Nutrient Expert with NCU (75%) + VC (25%) (N2) recorded significantly higher gross energy output and net energy return as compared to nitrogen omission (N5) and absolute control (N6). Application of nitrogen as per recommendation of Nutrient Expert with NCU (75%) + VC (25%) (N2) recorded significantly higher energy use efficiency (EUE) and energy productivity (EP) than all other nitrogen management practices except recommended doses of nitrogen with NCU (75%) + VC (25%) (N4). Absolute control (N6) required significantly higher specific energy. Application of nitrogen as per recommendation of Nutrient Expert with NCU (N1) recorded significantly higher energy intensity in economic terms over nitrogen omission (N5) and absolute control (N6).
