Today, the agricultural sector is heavily dependent on energy to meet the growing demand of world's growing population for food. This study aims to determine energy indices and equations based on energy consumption and production. 380 farmers out of the total number of 31190 irrigated wheat farmers of Isfahan were selected across the 24 boroughs of the province (based on Cochran'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 fertilizers 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.
