The use of coated phosphate fertilizers can be a new option in reduction of P adsorption by soil particles, thereby providing element longer allowing better nutrition of plants and consequent gain in grain yield. The experiment was conducted in Selvíria, MS, Brazil, in a dystrophic red latosol (Oxisol) with clay texture. The experimental design was a randomized block, arranged in a 4 x 2, 4 doses of P2O5 (0, 50, 100, and 150 kg ha-1) and two sources of phosphorus (monoammonium phosphate (MAP) and monoammonium phosphate coated by polymers) with 4 repetitions by evaluating the residual effect of these treatments. The experiment was conducted in corn off-season, in 2009 and 2010, under no-tillage system. The MAP and the coated MAP did not differ in the components used in the two seasons. The residual doses of P2O5 did not affect the leaf P concentration, and the yield components in general, however, the P2O5 doses influenced the weight of 100 grains and grain yield in 2010 and 2009, respectively.
