Sowing and fertilization were performed using a pneumatic precision seeder-fertilizer (Jamil®, model JM2090EX.00), with approximate weight of 1,160 kg, mounted on the three-point hitch of the tractor, set with three lines spaced by 0.80 m, plow shank for fertilizer deposition and offset double disc for seed deposition, with vertical pneumatic disc for seed metering. Fertilizer and seed distribution systems were activated through a concave rear sprocket made of rubber, with central relief for seed compaction. Fertilizer and seed deposits had capacity for 39 L and were completely filled. The precision seeder was equipped with a 35-cell disc and pneumatic meter. Hybrid corn seeds were used, at a population of 62,500 plants ha-1 and interrow spacing of 0.80 m. The amount of fertilizer and seeds was determined according to the recommendation for the corn crop. The fertilizer NPK was used, in the proportion of 10-28-20.
