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 main factors in this study, four different tillage methods as a main factors and  sub factors includes two maize varieties, including single cross 704 and maxima were considered. Also for soil physical properties statistical analysis, randomized complete block design was used. based on the results? different tillage methods on soil physical properties and yield of plants showed significant differences at 1%. Most of the yield was related to corn single cross 704 and twice of disc tillage in depth of 15-10 cm, with 88/18 tons per hectare. The greatest amount of soluble sugars and protein was obtained from corn single cross 704 with cultivator with blade and light disk with depth of 8 to 10 cm. thus it can be concluded that reduced tillage methods in dry and warm regions through Improve soil structure and retain moisture, resulting the yield of quantitative and qualitative of diffrent agricultural products will Increase.

Keywords: soil, corn, physical properties,  tillage methods, quantitative and qualitative yield.
