Abstract: This study examines the energy balance between the input and the output per hectare for an apple orchard in the West Azarbaijan province in Iran (2008-2009). Data were collected by using random sampling method for 80 "face to face" questioners. Results showed that the highest share of energy consumption belongs to packaging (57%) and irrigation (16%). The highest share of expenses was found to be 34% and 30% for labor and packaging, respectively. The total energy input for apple production, energy productivity, net energy and output-input energy value were estimated as 101,505 MJ/ha, 0.23 kg/MJ, -56,320 MJ/ha and 0.44, respectively. Results indicated that 71% and 96.7% of total energy input were in indirect and non-renewable form, respectively. The benefit-cost ratio was estimated as 1.77. The regression results revealed that all exogenous variables (for machinery, fertilizers, farmyard manure and packaging energies) were found statistically significant. The packaging had the highest impact (3.23). According to the benefit-cost ratio, large farms were more successful in economic performance.
