Determination of Energy Production Function in Irrigated Wheat of Isfahan Province

Today, the agricultural sector is heavily dependent on energy to meet the growing demand of worldchr('39')s growing population food. This study aims to determine energy indices and equations based on its energy consumption and production.  380 farmers out of total number of 31190 irrigated wheat farmers of Isfahan were selected across the 24 borough of the province (based on Cochranchr('39')s relationship) and the required information was acquired for calculating energy consumption indices and energy equations. According to the results, the total amount of energy consumed and produced by wheat in Isfahan province was estimated to be 92714.8 MJ/ha and 131958.8 MJ/ha, respectively. The total energy consumption consisted of 55820.6 MJ/ha renewable and 36894 MJ/ha non-renewable energy. The results of the energy production function showed that only fertilizer and transport energy coefficients were significant at 10% level. Regarding the return rate scale that was in the third region of productions, more energy consumption will reduce the energy production of wheat.
