Resumo: | Advancing nitrogen (N) application in cropping systems, using cover crops, is an alternative to improve the efficiency of use of this nutrient and to optimize the operational issue. The aim of this study was to evaluate the efficiency of advancing N fertilization for corn crop, with Brachiaria ruziziensis as cover crop. The experiment was conducted at the experimental field of the Federal University of Jataí / Regional Unit of Jataí, GO, Brazil, with history of soybean-corn/sorghum succession in the last 20 years and a high organic matter content in the soil, which reaches 39.5 g kg-1. A randomized complete block design was used in a 5x2 + 1 factorial scheme with 4 replicates, corresponding to five N doses: 0; 50; 100; 150 and 200 kg ha-1 and two times of application in B. ruziziensis: Time 1 - N application 90 days before planting of corn, and Time 2 - N application 60 days before planting, plus an additional treatment with conventional N fertilization, 150 kg ha-1 of N, not advanced, applied to the corn crop, split into planting fertilization and top-dressing fertilization. Except for the N dose of 200 kg ha-1 applied 90 days before corn sowing, advancing N fertilization for this crop using B. ruziziensis as cover plant proved to be as efficient as conventional fertilization for the soil and climate conditions under which the study was carried out, that is, soil with high content of organic matter, built fertility and absence of water restriction. |

Objetivou-se com este trabalho, avaliar a eficiência da antecipação da adubação nitrogenada para a cultura do milho, tendo a braquiária como cultura de cobertura. O experimento foi conduzido na área experimental da Universidade Federal de Jataí, em Jataí – GO, com histórico de plantio em sucessão soja-milho/sorgo nos últimos 20 anos, e destaque para o teor de matéria orgânica do solo que é de 39,5 g kg-1. Utilizou-se delineamento de blocos ao acaso, com fatorial 5x2+1, com 4 repetições, sendo cinco doses de N: 0; 50; 100; 150 e 200 kg ha-1 e duas épocas de aplicação na cultura da braquiária, sendo a época 1: aplicação do nitrogênio 90 dias pré-semeadura do milho e época 2: aplicação do nitrogênio 60 dias pré-semeadura do milho e um tratamento adicional com adubação nitrogenada convencional de 150 kg ha-1 de nitrogênio, aplicada na cultura do milho, dividida em adubação de plantio e cobertura. Com exceção a dose de 200 kg ha-1 de N aplicada 90 dias antes da semeadura do milho, a antecipação da adubação nitrogenada para esta cultura, utilizando a braquiária como planta de cobertura, se mostrou tão eficiente quando a adubação convencional nas condições de solo e clima em que foi realizado o trabalho, ou seja, solo com alto teor de matéria orgânica, fertilidade construída e ausência de restrição hídrica.Universidade Federal Rural do Semi-Árido2021-03-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/943210.1590/1983-21252021v34n102rcREVISTA CAATINGA; Vol. 34 No. 1 (2021); 9-19Revista Caatinga; v. 34 n. 1 (2021); 9-191983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/9432/10551Copyright (c) 2021 Revista Caatingainfo:eu-repo/semantics/openAccessOliveira, Thiago Pinheiro deBraz, Magno GonsalvesSmaniotto, Alex OliveiraSilva, Danielle Fabíola Pereira daCruz, Simério Carlos Silva2023-07-19T12:23:13Zoai:ojs.periodicos.ufersa.edu.br:article/9432Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:49.321867Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
