Abstract

WEIRICH NETO, Pedro H. et al. No till corn seeding with and without mechanichal management of dry matter. Eng. Agríc. [online]. 2012, vol.32, n.4, pp. 794-801. ISSN 0100-6916.  http://dx.doi.org/10.1590/S0100-69162012000400019.

The aim of this study was to determine whether the corn is influenced by the management of dry oat before sowing, by the use of roller-Loosening. The treatments consisted of sowing the corn in the oat dry matter without mechanical handling and rolled. The experiment was conducted in four properties, two in the 2007/2008 harvest, and two others in the 2008/2009 season. The experimental design was randomized blocks with 11 repetitions, which plots had 80 m2 each. It was evaluated the quality of sowing and yield components. It was concluded that in the four agricultural properties and two years mechanical handling of the oat straw before sowing the corn significantly increased the spacing flawed, significantly reduced the acceptable spacing and did not affect the  corn yield, and only increased the cost of production.

Keywords : oat; roller-Loosening; yields components.
