Abstract :
The reasons of using conservation tillage in preparing the seedbed in addition of increasing soil fertility, reducing waste of energy and depreciation of machinerie and saving the time for operations. In this casc, identifying and using resources management and the saved inputs according to the kind of tillage is abig step in order to optimizingenergy consumption and promoting the energy productivity. In this study, in addition to determining the rate of energy consumption in different methods of tillage for formatting the wheat in Fars, khoozestan, and Esfahan provinces, the effect of various factors on energy productivity have been studied. so, some questionnairs were distributed in the conservative farms in different areas of these eities. The results showed that the most rate of energy Consumption is related to the using fertilizer; and its most rate is in khoozestan. But the most energy consumption has related to the irrigation in Esfahan and Fars provinces. Also , it was determined that the average of energy productivity has been 0.15 kg.MJ-1 in these provinces. The most energy productivity has obtained in cold region. The most energy productivity wasobtained in medium textures with good structure and high organic materials. The most energy productivity was obtained in different methods of managing the crop residues, in consecrating the stood remains with surface irrigation methods.
