Abstract: Agricultural ecosystems are related to economical and society condition widely, that there are in world. The major target of agricultural ecosystems management is maximum energy flow and human service materials. Energy cycle is a subject of agricultural ecology and in different locations of world, input and output energy are calculated in different agricultural ecosystems. A way of estimation agriculture development and product stability in agricultural location in using of energy flow method. In this consideration, energy flow at agricultural ecosystem of wheat under rained farming was evaluated with using of statistics and information related province agricultural organization (preparation of questionnaire from province farmers). The related data of inputs and outputs are become equivalent values of input and output energy, than was calculated energy efficiency. Energy value of used factors and inputs of this type cultivation was 3906663.848 kcal ha-1 and output (production) energy value of wheat grain yield 4068475.6 and 3118380.72 kcal ha-1, respectively. Also, energy efficiency value (output: Input ration) was 1.84 that energy efficiency value of grain and straw were 1.04 and 0.8, respectively.
