One of the factors affecting the physical properties of soil and crops is tillage systems. The experiment was conducted in summer 2012 at the research farm of Islamic Azad University. This study was performed by experiment a split plot in a randomized complete block design with three replications. The factors in this study, four different tillage methods were considered. For soil physical properties statistical analysis, randomized complete block design was used. Based on the results، different tillage methods on soil physical properties showed significant differences at 1%. According to the results, the high amount of humidity in after ploughing and postharvest respectively of conventional tillage methods, and twice the disk and the lowest bulk density after tillage in the conventional tillage was obtained. Also the highest rate of crushed soil tillage with rotary plough was calculated.
