CICLAGEM DE NUTRIENTES DO CAPIM-QUÊNIA APÓS O CONSÓRCIO COM MILHO PARA A PRODUTIVIDADE DA SOJA

Abstract

The success of the labor-livestock integration system is directly we specify the appropriate choice of forage and sowing method, to promote adequate soil coverage, ensuring agricultural sustainability and crop diversification production. Therefore, the objective was to evaluate nutrient cycling in the biomass of Kenya grass after intercropping with corn, for soybean productivity. The experiment was Run in a randomized block design with four replications. The treatments consisted of soil cover biomass: corn in monoculture; Kenya grass in monoculture; corn intercropped with Kenya grass in the row; corn intercropped with Kenya grass between the rows and an additional soybean treatment without cover biomass. The results demonstrated the corn cultivation system intercropped with Kenya grass in between rows is more recommended in relation to sowing in the same row as the corn, because promote greater nutrient cycling. Integrated production systems are a technique promising and efficient for production systems compared to the cultivation system of corn in monoculture and soy without soil cover biomass, which guarantees greater sustainability of agricultural systems.
