Resumo: No-tillage system in cerrado regions assumes importance due to the fact that it does not turn over the soil, to use cover crops and to recommend crop rotation. The objective of this research was to evaluate the effect of the amount of lime applied during the period, cover crops in the off season and nitrogen doses, in the 2015/16, 2016/2017 and 2017/18 crops in the nutrient leaf content and grain yield of maize. The study began in 2000/01 in an experimental area in the Selvíria, MS, Brazil in Oxisol, where the no-tillage system was initiated. The experimental design used was the randomized blocks with three replications in a factorial arrangement 5x2x3, consisting 5 residual combinations of lime and gypsum association (6.92 (T1), 11.44 (T2), 7.73 (T3), 10. 63(T4) and 0.81(T5) t ha-1, where T3 and T4 received in February/2017, 1.7 t ha-1 of gypsum), 2 cover crops in the off-season (Crotalaria juncea and Pennisetum americanum) and 3 N doses as top dressing (0, 90 and 180 kg ha-1). The residual doses of lime with or without gypsum did not change the grain yield of maize; the increase N doses as top dressing provided an increase in grain yield in the 3 agricultural years of the research, and the maize crop after crotalaria presented lower demand for nitrogen.

El objetivo de esta investigación fue evaluar el efecto de la cantidad de cal aplicada durante el período, los cultivos de cobertura en la temporada baja y las dosis de nitrógeno, en los cultivos de 2015/16, 2016/2017 y 2017/18 en el contenido de nutrientes en las hojas y el rendimiento del grano de maíz. El estudio se inició en 2000/01 en una zona experimental de la Selvíria, MS (Brasil) en Ferralsol, donde se inició el sistema de siembra directa. El diseño experimental utilizado fue el de bloques aleatorios con tres réplicas en un arreglo factorial 5x2x3, que consistía en 5 combinaciones residuales de cal y yeso (6,92 (T1), 11,44 (T2), 7,73 (T3), 10. 63(T4) y 0,81(T5) t ha-1, donde T3 y T4 recibieron en febrero/2017, 1,7 t ha-1 de yeso), 2 cultivos de cobertura en la temporada baja (Crotalaria juncea y Pennisetum americanum) y 3 dosis de N como recubrimiento (0, 90 y 180 kg ha-1). Las dosis residuales de cal con o sin yeso no modificaron el rendimiento de los granos de maíz; el aumento de las dosis de N como recubrimiento superior proporcionó un aumento del rendimiento de los granos en los 3 años agrícolas de la investigación, y la cosecha de maíz después de la crotalaria presentó una menor demanda de nitrógeno.No cerrado, o sistema de plantio direto assume importância devido a não revolver o solo, utilizar culturas de cobertura e preconizar rotação de culturas. Assim, o presente trabalho de longa duração, foi desenvolvido objetivando avaliar nas safras 2015/16, 2016/2017 e 2017/18, o efeito da quantidade de calcário aplicada ao longo do período, culturas de cobertura na entressafra e doses de nitrogênio, sobre os teores foliares de macronutrientes e produtividade de grãos do milho. O trabalho iniciou-se em 2000/01, em área experimental no munícipio de Selvíria, MS, Brazil, em LATOSSOLO VERMELHO distrófico, onde se iniciou o sistema plantio direto. O delineamento foi o de blocos casualizados com três repetições, e os tratamentos dispostos em esquema fatorial 5x2x3, ou seja, 5 combinações residuais de associação de calcário e gesso (6,92 (T1), 11,44 (T2), 7,73 (T3), 10,63 (T4) e 0,81 (T5) t ha-1, onde T3 e T4 receberam em fevereiro/2017, 1,7 t ha-1 de gesso), 2 culturas de cobertura na entressafra (Crotalaria juncea e Pennisetum americanum) e 3 doses de nitrogênio em cobertura no milho (0, 90 e 180 kg ha-1). Os residuais das doses de calagem com ou sem gessagem não alteraram a produtividade de grãos de milho; o incremento das doses de N em cobertura proporcionou aumento na produtividade de grãos nos três anos agrícolas da pesquisa, sendo que a cultura do milho após crotalária apresentou menor demanda de nitrogênio.Research, Society and Development2020-08-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/594310.33448/rsd-v9i8.5943Research, Society and Development; Vol. 9 No. 8; e924985943Research, Society and Development; Vol. 9 Núm. 8; e924985943Research, Society and Development; v. 9 n. 8; e9249859432525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/5943/6019Copyright (c) 2020 Vinicius Cabrio Fernandeshttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessFernandes, Vinicius CábrioLazarini, EdsonSanches, Izabela RodriguesSantos, Fabiana Lopes dosBossolani, João William2020-08-20T18:00:17Zoai:ojs.pkp.sfu.ca:article/5943Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:29:16.902272Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false
