Fulfillment of a suitable tillage methods are one factors important management that they can effect on soil physical properties and quantity and quality yield. This investigation was carried out to test effects of susoiler on soil physical properties and quantity and quality yield of winter wheat in vertisol soils, based on a split plot with randomized complete block with three replications at Mahidasht Agricultural Research Station for 2 years (2008-2010). The experimental variables including two methods of tillage (chisel and moldboard) as sub plots and five methods of susoiler (no-susoiler, once susoiler at depths 0-30 cm, twice susoiler at depths 0-30 cm, once susoiler at depths 60 cm and twice susoiler at depths 60 cm ) as main plots. In this project, in order to examine and determine the changes created in physical properties of soil and quantity and quality yield were studied one depths 0-30 cm. Soil physical analysis including bulk density, total porosity, MWD, Ks and quantity and quality yield were measured. The result showed that using the susoiler become significant differences so that using the twice susoiler at depths 60 cm is much preferable due to improving the soil physical and quantity and quality yield. Therefore application of (twice susoiler at depths 60 cm + moldboard ) and (twice susoiler at depths 60 cm + chisel) treatment is recommended for the area.
