Desempenho agronômico do milho em sistema de manejo do solo

Abstract

The present work aims to evaluate the corn crop responses in the plant height, stalk diameter, first spike height, number of spikes per plant and productivity depending on the different types of management. The experiment was carried out at the experimental farm of the Federal University of Grande Dourados - UFGD, MS. There were six different types of management applied to the soil: no tillage, chisel plow at 0.35 m, cross-chisel plow at 0.35 m plus a leveling disk harrow, disk harrow, plow at 0.40 m with a disk harrow of two gradients, and chisel plow to 0,35 m with disk harrow. The plant stand and a longitudinal distribution at normal, faulted and double spacing did not differ for soil management, while higher yields were obtained in the management systems with plowing or scarification associated with the harrowing.
