Soil use and management during the winter can affect soil physical properties, reminiscent straw and performance of the crop cultivated in succession. The objective of this study was to evaluate the effect of winter soil use on these variables, cultivating black bean under no tillage system in the summer. Three experiments were carried out in the North Plateau of Santa Catarina State, Brazil, during 2007/08 crop season, with five strategies of soil use during the winter: 1) multicropping with black oat + ryegrass + commom vetch + arrow leaf clover without grazing and nitrogen fertilization (multicropping cover); 2) the same multicropping, with grazing and 100kg ha^-1 of nitrogen fertilization (pasture with N); 3) the same multicropping, with grazing and without nitrogen fertilization (pasture without N); 4) oil seed radish, without grazing and nitrogen fertilization (oil seed radish); and 5) natural vegetation, without grazing and nitrogen fertilization (fallow). Highest straw dry mass is verified in multicropping cover, but the strategies of winter soil use do not affect significantly the soil bulk density and macroporosity. The soil use with winter annual pasture in crop-livestock system, cover crops and fallow does not affect the black bean performance in succession, under no tillage system.
