The results reported in this paper did not show statistical differences in production of seeds, number of plants and number of ears when corn fertilizer (combination of Chilean nitrate, superphosphate and potassium chloride) was applied either in the sowing furrow or in lateral furrows (one or both side). The treatments with fertilizer were better than the treatment without fertilizer used for comparisons. Cotton seed meal, used in combination with superphosphate and potassium chloride, placed in the sowing furrow, reduces statistically the number of plants in the row when compared with the treatments where applications were made only in lateral furrows. However, this reduction of plants did not affect significantly the number of ears and the production in the treatments.
