Agricultural machineries must be chosen in such a way that provides the best condition for seed germination and root-growth through consuming less energy. In this research, the effect of different tillage methods (moldboard plow with two disks, chisel plow with two disks, two disks and control (Conventional tillage) on yield and energy indexes was studied. The results showed that different tillage methods had significant effect on emergence percentage, but any significant effect in yield components was not observed. Input energy of treatments was qualitatively significant and minimum energy was related to two disks treatments with 9652 MJ. Influence of tillage methods on output energy and energy productivity was not significant. Results revealed that the maximum energy efficiency was related to tillage method with two disks.
