Abstract	This work evaluated the productivity and the nutrient absorption by a corn crop using manure of swine reared in a full-cycle system. The experimental design used was completely randomized, with 4 replications. The treatments were arranged in a 4 x 2 + 2 factorial scheme, with 4 doses of swine manure (20, 30, 40 and 50 m 3 ha -1 ), applied before sowing and two forms of cover fertilization (90 kg of N in urea form and 20 m 3 ha -1 of swine manure); and two additional treatments, with NPK chemistry fertilization, in the ratios of 10, 100 and 45 kg ha -1 , respectively, with two forms of cover fertilization (20 m 3 ha -1 of swine manure and 90 kg of N in urea form), totaling 10 treatments and 40 parcels. Productivity in kg of grains ha -1 and nutrients concentration in the leaf were evaluated. The treatments that received urea in cover were superior to treatments that received swine manure in cover. There was no statistically significant difference among treatments that received chemistry fertilizer (NPK) and swine manure, which indicates that the utilization of swine manure as a biofertilizer can be one of the alternatives for its use.
