During the 1986/94 growing seasons, experiments were carried out on a Red-Dark Podzolic soil at the Experimental Station of Monte Alegre do Sul-SP, Brazil, in order to verify the continuous and noncontinuous peanut planting, the incorporation of green manure, of chicken manure and leaving the soil fallow, on the spring productivity of peanut crop. The use of incorporated Mucuna aterrima, as green manure, in rotation with peanut, increased the percentual yield by 64% of the continuous peanut planting; two annual cropping systems of peanut can not be grown, because reduce yields. Incorporation of Mucuna aterrima as green manure, chicken manure and fallow increased the concentration of the phosphorus in the soil, when compared to the continuous planting of peanut crop.
