Resumo: |
Corn is one of the main products produced and marketed worldwide. However, to obtain high productivity necessary to apply synthetic chemical fertilizers, which usually can be harmful to the environment. Because of this, the objective to evaluate the effect of application of organic matter via compost and green manure on corn productivity. The experiment was conducted in a randomized block design, installment scheme subdivided (3 x 3 +1), three vegetables on the plots (Sunn hemp, pigeon pea beans and dwarf beans macassar), three volumes of organic compound in sub-subparcelas (0, 20 and 40 t ha-1) and an additional witness (Chemistry). The variables analyzed were: height of the plants; height of insertion of the first COB; culm diameter; leaf area; chlorophyll content; foliar N content; crude protein content; dry mass; average number of spikes per plant; diameter and length of spikes; number of row of grain; number of grains per row; mass of 1,000 grains; grain productivity; total organic carbon and soil organic matter. The data were subjected to analysis of variance and averages compared by Tukey test at 5% probability. To the study of organic compound concentrations was employed to linear regression analysis. The statistical analyses were performed by Software SAEG 9.1 version. There was no significant difference to chlorophyll a and b, N and crude protein content, just to the right a/b. Maize plants subjected to the green bean fertilizer macassar showed difference with respect to total chlorophyll, being higher than the other legumes. For leaf area production variables, diameter of the cob, COB length, number of Spike and productivity showed a statistically significant difference. Total organic carbon and soil organic matter after the cultivation of corn, showed no statistical difference. The amount of 40 t ha-1 of the organic compound fertilizer green beans macassar caused greater yields of corn. |
