AVALIAÇÃO DA PRODUTIVIDADE DA SOJA SOB APLICAÇÃO SUPLEMENTAR DE NITROGÊNIO

Abstract

Soy, like any plant, needs nutrients to grow in the soil it is grown on. In search of high productivity, new work has always been done with a focus on plant nutrition. With this there are several nutrients that are essential for a plant to develop, knowing this work sought to study the issue of supplemental nitrogen in soybean plants. The work was carried out in the municipality of Rio Verde-Goiás, on a private property in the rural area of ​​the city, where the experiment was carried out in DIC (Fully Randomized Design), with a total of 12 plots. A fixed dose of Urea (nitrogen source) of 30 kg / ha was tested in the treatments, but each at a different stage of the crop's development. The cultivar installed was NS7901RR, where the work started with planting on 10/23/2018. In this work, PMG (Weight of Thousand Grains), MS (Dry Matter) and productivity were evaluated. After harvesting and analysis of the data, it was concluded that supplementary urea fertilization in soybeans was not significant in any of the evaluated criteria.
