Use of biofertilizantes phosphated of the development of the melon and readiness of phosphorus

Abstract

This work assessed the development of melon crops,and the availability of phosphorus in the soil with the use of biofertilizer phosphate after three cycles of culture. The treatments were distributed into randomized block design with three repetitions, arranged in a factorial 2 x 3 x 7, corresponding to two types of soils (Yellow Latossol and Fluvic Neosol); three sources of phosphorus (triple superphosphate, bio-fertilizer phosphate and rocks) and seven levels of phosphorus (0; 0.5; 1.0; 1.5; 2.0; 2.5; 3.0 of recommended for the culture and for each soil). The triple superphosphate fertilizer, biofertilizer rock phosphate and rock phosphate showed no significant differences in dry matter production, but the biofertilizer was the most available P in both soils after three cycles of the same culture.
