Evaluation of different soil management on corn productivity (Zea mays) in organic production system

Abstract

The rational use of soil has been aim of research and discussions due to the need for technological
alternatives that enable the correct management of the soil and a sustainable agriculture.
This present paper aimed to analyze the production of maize submitted to different soil preparation,
namely: no-tillage system, minimum system of cultivation and conventional cultivation
system. The experiment was conducted in Seropédica, State of Rio de Janeiro, , in a randomized
block design and three replications, in Red-Yellow Argisoil. The evaluations used were:
total yield of spikes with straw (kg / plot) and grain yield (kg ha-1). The results showed that grain
yield is not influenced by the soil management system. Thus, it can be inferred that no-tillage,
without herbicide use, is a viable alternative for organic production systems.
