| ABSTRACT Melon producers, in Chapada do Apodi, Rio Grande do Norte State, Brazil, located between the states of Ceará and Rio Grande do Norte, have cultivated corn in succession to the melon crop. However, this crop rotation is not yet evaluated on the extent to which the residual effect of nitrogen and phosphate fertilization carried out in melon can supply partially or completely the corn demands of nitrogen and phosphorus. This work aimed to evaluate the effect of nitrogen (N) and phosphorus (P) in the production of corn in succession to the cultivation of melon (Cucumis melo) irrigated in an Alkaline Inceptisol of Chapada do Apodi. Ten treatments from the combinations between five N rates (0; 45; 90; 160 and 220 kg/ha) and four levels of P2O5 (0; 40;... |
