Condiciones del suelo y rendimiento del maíz en relación con diferentes sistemas de cultivo.

Abstract

Field tests were carried out with the aim to evaluate soil condition induced by three tillage systems: moldboard plow, chisel plow and no till and the effects of tillage on three corn hybrid's yield. Field plots were established on a Typical Argiudol. Penetration resistance was determinate previous the tillage treatments and during the corn growth. Moldboard and chisel plows made depth to 1,5 MPa cone index significantly deeper than no till at the different sample's times. There were no interactions between hybrids and tillage treatments. Tillage systems affects corn grain yield
