Abstract: A field experiment was conducted during 2007 and 2008 to study the effect of integrated nutrient management on yield, economic and energy parameter in maize under irrigated condition. Application of 75% RDF + 25% N through FYM + Azo. + PSB recorded significantly higher seed yield (40.30 qha-1), stover yield (54.96 qha-1), biological yield (95.26 qha-1) and harvest index (42.28%). The energy output (127941MJha-1) and energy balance (115423MJha-1) was higher in 75% RDF + 25% N through FYM + Azo. + PSB. However, the energy balance per unit input (9.47) and energy output/input ratio (10.47) was maximum due to 100% N through organic manure (50% N through FYM + 25% N through vermicompost + 25% N through neemcack + biofertilizers (Azo. + PSB). Maximum net returns (Rs. 32228 ha-1) and B:C ratio (2.19) was recorded in 100% RDF through inorganic source alone. The lowest value in yield and energy parameter were observed in control treatment. Therefore it can be concluded that energy output, energy balance, energy balance per unit input and energy output/input ratio was increased with higher inorganic nutrient level coupled with lower organic manure nutrient levels.
