The soil physical properties are influenced by different soil tillage as well as by crop rotation. Thus, this study was carried out in Selvíria, Mato Grosso do Sul State, in 2003/2004, aiming to evaluate the shoot dry matter production, soil covering percentage, and the influence of crop rotation and tillage system on soil physical properties of a Rhodic Hapludox and to evaluate irrigated winter common bean yield. The experimental design was a randomized block, arranged in a split plot scheme, with four replications. The plots consisted of soil tillage system (heavy harrow, chisel plow and no-tillage) and the subplots of six crop rotations sown in the summer (corn, corn + black velvet bean, corn + brachiaria grass, soybean, rice and sunhemp). The crop rotations that presented larger soil coverage and shoot dry matter production were sunnhep, corn + black velvet bean, corn + braquiaria grass and corn. No-tillage resulted in larger values of penetration resistance at 0.00 - 0.10 m layer. Except macro porosity at 0-0,1 m layer, the properties humidity, macroporosity, microporosity and total porosity of soil are not influenced by soil tillage systems. Despite differences in some yield components of common bean due to certain soil tillage or crop succession, the irrigated winter common bean crop yield was not affected.
