The aims of this study were to determine the input and outputs energy for maize production in Islamabad, Pakistan. Results showed that grain yield, number of grain per cob, 1000 grain weight and plant height were maximum at deep tillage as compared to conventional and lowest in zero tillage. Total input energy was maximum in combined application with NPK + FYM fertilizer as compared to FYM, NPK fertilizer alone and low in control where no fertilizer was applied. The output energy was gained in deep tillage where combined NPK + FYM were applied and lowest energy was gained in control plots. The results showed that combined NPK + FYM fertilizer level gave highest grain yield in deep tillage against conventional tillage and low grain yield was recorded in zero tillage. Although deep tillage consumed more energy as compared to conventional and lowest in zero tillage.
