Abstract:The purpose of this study was to determine the amount of input-output energy used in baled alfalfa hay production in Hamedan province. Data was collected from 80 alfalfa farms. The sample volume was determined by random sampling method. The total energy of 810574.87 MJ ha-1 was calculated for the 7 years production life and the establishment. The mean input-output ratio and productivity were calculated to be 1.88 and 0.119 kg MJ-1, respectively. The electricity used in pumping system was the highest energy inputs for alfalfa production (75.79%). It is followed by chemical fertilizers with 13.01%. The energy equivalences of human labour, biocide and machinery were found to be low. It was concluded that the nitrogen fertilizer can be substituted by other fertilizers that have less consumption of energy.
