Evaluation of corn productivity in no-tillage system without herbicide use.

Abstract

One of the great challenges in the implementation of no-tillage in organic production system is to make it compatible without the use of herbicide. The aim of this study was to evaluate the yield of green corn submitted to different forms of soil preparation. The experimental design was a randomized block design with four replicates. Three types of soil preparation were established: a) no-tillage, no herbicide use and with the use of a waste disposer (Triton); b) soil tillage through rotary tillingand c) soil tillage through plowing and two harrowing. The results showed that the no-tillage system, without herbicide use, yields corn productivity is equal to the soil tillage through plowing and two harrowing and with rotary tilling. It canbeinferred that the no-tillage system, without herbicide use, has the potential to be inserted in organic management.
