The corn crop productivity, common bean and wheat in Brazil are considered low, once, using more appropriate techniques of soil and plants management, it is possible to get success, in short period, to increase the productivity obtained with those crops. Several causes they have pointed for this low productivity, among them it is the use of fertilizers and consequently, with the continuous cultivation, leading to reduction in the soil fertility destined to the annual crops. The conditioning of soil fertility, the organic matter has highest importance and its appropriate management it is necessary to get good harvests. This project has as objective to study the effect of brachiaria consortium, crotalaria and velvet bean in the development and production of the corn in the normal crop and, cultural remains of those cultures and doses of nitrogen in the development and productivity of the winter common bean and wheat in no till system. The project will be developed in two agricultural years in experimental area of FEIS belonging to Engineering University of Ilha Solteira - UNESP, located in Selvíria county - MS. The soil of the place is a Red Latosol, loamy textured, originally under savannah vegetation. The annual precipitation is 1,370mm, the medium annual temperature is 23.5ºC and the annual relative humidity of the air between 60 and 80%.
