Title: Production of hybrid corn under doses of bovine manure
Abstract: This work aimed at evaluating the production of hybrid corn under different levels of fertilization with bovine manure. The work was conducted in the experimental station of the Academical Campus of Gurupi of the Federal University of Tocantins. The experimental design used was in randomized blocks (RBD), with six replications. Each block was composed by eight treatments: 0, 10, 20, 30, 40, 50, 60 t ha -1 of organic fertilizer (tanned bovine manure) and chemical fertilizing with 500 kg ha -1 of 4-14-8 + Zn. The simple hybrid corn was used DAS655, on a Latossolo Vermelho-Amarelo Distrofico tipico (EMBRAPA, 2006). The appraised parameters were: height, diameter of the stem, number of leaves, height of the base of the first corn ear, number of leaves above the first corn ear, number of ramifications of the tassel, angle of the tassel, angle of the third leaf, length of the tassel, number of grain rows, number of grains per rows, diameter of the ear of corn, length of the ear of corn, dry matter of the plant and leaf area. The organic fertilization influenced significantly in the height of initial plant, diameter of the stem, number of leaves, leaf area and diameter of the ear of corn of the culture of the corn. The application of the tanned bovine manure in the planting furrow can substitute the chemical fertilization, without committing the performance of the culture for the forage production.
