For planting fertilization, 300 kg / ha of the following formulated 2-25-6 (2% Nitrogen, 25% P2O5 and 6% K2O) will be required. As a form of irrigation management, a 12.04 mm water depth was adopted, representing approximately 50% of the pivot's activity capacity, being switched on in the final two months of the corn cycle. Maize was planted in the santa fe system (consortium between maize and grass pasture after cultivation) in which at the time of sowing 4 kg / ha-1 of Brachiaria ruziziensis was applied with a Cultural Value (VC) of 78%. in view of a recommendation to cover fertilization of 200 kg / ha of urea and 150 kg of kcl. Where the pests and diseases found during the corn cycle were brown spot, polishing rust, diplodia, aphid, cartridge caterpillar, leafhopper, the result of the harvest, clean and dry, was 4920 kg / ha, sold in the 60 kg bag to R $ 55.00, ending a profitability of R $ 1925.00 per hectare.
