Abstract
Today, the agricultural sector in order to meet supply more food for a growing population and provide adequate nutrients, in highly energy intensive. Concerns relating to the conservation of fossil fuels and emissions of greenhouse gases leads to an increase in research on energy balance in crop production systems has been. This study was conducted to assess energy efficiency in rainfed and irrigated wheat production systems in Kermanshah city is doing. Field operations and questionnaire data were collected. Completed questionnaires style interview took place on farms. The amount of input energy to dry and irrigated wheat fields, respectively, 14520.8 and 41921.8 energy output fields, respectively 27309.78 and 65720.7 was calculated. The greatest share of energy inputs for both fertilizers and fossil fuels was the agroecosystems.energy efficiency for dryland wheat and blue respectively 1.88 and 1.56 respectively. Level of energy efficiency for dryland wheat 0.11 and for wheat 0.09 obtained indicate that dryland wheat production system was efficient wheat production systems. Energy levels for dry and irrigated wheat respectively 9 and 10.7 was calculated which indicates that the wheat production system for producing more energy is consumed per kilogram of product and rainfed wheat production system was more efficient in this regard. The amount of net energy for dryland and irrigated wheat respectively 12788.98 and 23798.9 was calculated, Indicates that the net energy output was higher in irrigated wheat fields.
