- Abstract
This study aimed to evaluate the performance agronomic of grain sorghumas a function of Nand-P2O5, as well as the economic analysis in the municipality of Mossoró-RN. The treatments consisted of the combination of four N rates (30,60, 90 and 120 kg ha-1) and four doses of P2O5 (30,60, 90 and 120 kgha-1) and a control treatment. The experimental design was a randomized complete block with four replications in a factorial design. The characteristics evaluated were:plant height,stem diameter, panicle length, panicle diameter, dry matter, grain yield, nitrogen and phosphorus content in leaf nitrogen content, phosphorus in the soil, gross receipts, expenditures on fertilizer and net income. The increased availability of nitrogen and phosphorus in the soil influence the variables studied, except the nitrogen content in soil. While most production grain has been estimated for the application of 87.62 kg ha-1 N +120 kgP2O5ha, the maximum dose recommended environmental and economic efficiency were 60 kg Nha-1+ 120kgha-1P2O5.
