This article examines energy consumption patterns and the relationship between input energys and Almond production function in hamedan province. The data was collected by a face-to-face interview method from 78 farms. The energy ratios for almond in this province was 16.19 . The net energy, energy productivity and Specific energy for almond was 49453 MJ ha-1 :1/62Kg MJ-1 and 1/54 MJ kg: respectively. .the Share of renewable, non-renewable, direct and indirect energy was obtaind 12/3: 87/7: 50/34: 66/49. An economic model to estimate the effect of energy input was developed by applying the Cobb-Douglas production function. Therefore, the productivity performance was considered function of the energy inputs. Return to Myas value (RTS) for the almonds, about 165/1, respectively. Benefit-Cost Ratio and Net worth was 03160605/ 52/13 و 08 tomans on any hectare: respectively.
