Análise do sistema de consórcio milho (Zea mays L.) e amendoim forrageiro (Arachis pintoi Krapov. & W.C.Gregory): contribuição à fertilidade nitrogenada do solo.

Abstract

This study analyzes the intercropping system of maize (Zea mays L.) and forage peanut (Arachis pintoi Krapov. & W.C. Gregory), with emphasis on its contribution to soil nitrogen fertility and integrated crop management. The research will be conducted under controlled conditions, comparing maize monoculture (with and without nitrogen fertilization) to the maize–forage peanut intercrop, evaluating parameters such as vegetative growth, efficiency of biological nitrogen fixation, and weed suppression. The experimental design adopted was a randomized block design, including soil chemical analyses and periodic agronomic evaluations. The expected results include the quantification of nitrogen input to the system, the technical feasibility of the intercropping strategy, and its effects on maize productivity and weed dynamics. The study aims to provide support for sustainable agricultural practices by reducing dependence on synthetic fertilizers and promoting soil conservation.
