Study of energy flow in ecosystem, especially in ecosystems that which are directly managed by human, is of great importance, because energy is flow of an ecosystem. Human could increase the efficiency of energy in agricultural products by applying management.In this survey the flow of energy in apple gardens of West Azerbaijan province ecosystem was calculated by using the statistics and information derived from agriculture (government) organization and providing of questionnaire from gardens of the province in 2009.Data's related to input and output are transferred to the rates equivalent to energy consumed and produced and then average energy was calculated (rate of output to input).The rate of applied energy is 11018330Kcal/ha and rate of produced energy is 10700 Kcal/ha, also rate of energy efficiency is 0.97. The result of this survey showed that main part of energy used in this product respectively consists of irrigation, chemical fertilizer and insecticide respectively.
We Could decrease energy efficiency by using drip irrigation systems, manure, insecticide, and pesticides considering to notice reduce the incidence of pests and diseases and so pace toward sustainable agriculture and decreased environmental pollution.
