The role of energy management is important and essential in sustainability of production systems. The aims of this study were evaluated the impact of different soil tillage on energy use in wheat agroecosystems. To purpose this research was carried on 2014 to 2016 years in research farm of Razi University in western Iran. The result of this study showed that total energy used in NT, RT, and CT systems was 31.39, 32.85, and 35.16GJha-1. In the other hands, production energy in NT, RT, and CT systems was 200.14, 207.68, and 195.26GJha-1. Accordingly, energy use efficiency (EUE) in NT, RT, and CT systems was 6.38, 6.32, and 5.55. Therefore, amount of EUE of different tillage systems followed the order of NT>RT>CT systems. In this research profitability of NT, RT, and CT systems were 3.23, 2.96, and 2.59. This result showed that more use of machinery and operation due to more use of energy resource can be reduced EUE, Net energy and profitability of agroecosystems.
