ADUBAÇÃO FOSFATADA MINERAL E ORGANOMINERAL NO DESENVOLVIMENTO DO MILHO

Abstract

The objective of this work was to evaluate the effects of the phosphorus on corn culture, submitted to the mineral and organomineral fertilizer. The experiment, realized on the Universidade do Oeste Paulista, by using a randomized complete block design, with eight treatments and four repetitions, four phosphorus doses (0, 30, 60 and 120 Kg of P2 O5 ha-1) in the absence and presence of 300 kg ha-1 of the organic fertilizer. 45 days after the emergency occurred the cut for determination of the dry matter, of the phosphorus tenor in the aerial part, and of the phosphorus accumulation in the dry matter. The organic fertilizer allowed a reduction in the phosphorus doses for the development of the culture of the corn and it elevated the tenor of accumulated phosphorus in the part aerial, same when of the application of low phosphorus doses.
