Resumo: The present study aimed to evaluate the influence of fertilization formulated at planting and doses of nitrogen in topdressing on the yield components of second-crop corn. The experiment was conducted between March and June 2018 on the farm of the State University of Goiás, University Unit of Ipameri-GO. The randomized block design, arranged in a 3 x 5 factorial scheme with four replications, was used. Three fertilizer formulations at planting (06-22-12; 08-20-15 and 06-22-12 + 2% organic carbon) and five doses of N (0, 50, 100, 150 and 200 kg ha-1) in topdressing were evaluated. Leaf nitrogen content, fresh and dry mass of leaves, plant height, stem diameter, first ear insertion height, length and diameter of ears, 1000-grain weight, the mass of plants per hectare, extraction of nitrogen, and grain yield were assessed. Given the results, NPK formulated fertilizers can be used indifferently to grow second-crop corn. Nitrogen doses in topdressing have satisfactory results up to the estimated rate of 135 kg ha-1 for the cultivation of second-crop corn.

O experimento foi conduzido entre os meses de março a junho de 2018, na fazenda da Universidade Estadual de Goiás, Unidade Universitária de Ipameri-GO. O delineamento experimental utilizado foi o de blocos casualizados no esquema fatorial 3 x 5 sendo três formulações de adubos na semeadura (06-22-12; 08-20-15 e 06-22-12 + 2% de carbono orgânico) e cinco doses de N (0, 50, 100, 150 e 200 kg ha-1) em cobertura, com quatro repetições. Determinou-se o teor de nitrogênio foliar, massa fresca e seca de folhas, altura de plantas, diâmetro do colmo, altura de inserção da primeira espiga, comprimento e diâmetro de espigas, massa de mil grãos, massa de plantas por hectare, extração de nitrogênio e produtividade. Diante dos resultados pode-se utilizar indiferentemente os fertilizantes formulados NPK na produção do milho safrinha. As doses de nitrogênio em cobertura apresentam resultados satisfatórios até a dose estimada de 135 kg ha-1 de nitrogênio para o cultivo de milho safrinha.Universidade Estadual de Mato Grosso do Sul, Unidade Universitária de Cassilândia2022-10-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicosonline.uems.br/index.php/agrineo/article/view/696810.32404/rean.v9i4.6968Revista de Agricultura Neotropical; v. 9 n. 4 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e6968REVISTA DE AGRICULTURA NEOTROPICAL; Vol. 9 No. 4 (2022): REVISTA DE AGRICULTURA NEOTROPICAL; e69682358-6303reponame:Revista de Agricultura Neotropicalinstname:Universidade Estadual de Mato Grosso do Sul (UEMS)instacron:UEMSenghttps://periodicosonline.uems.br/index.php/agrineo/article/view/6968/5209https://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSilva, Luciana Maria daSilva Junior, Rogério LamimLeão Pereira Resende, CecíliaMarangoni Montes, RafaelSantiago Silva Benett, KatianeBenett, Cleiton Gredson Sabin2023-01-18T22:13:40Zoai:ojs.pkp.sfu.ca:article/6968Revistahttps://periodicosonline.uems.br/index.php/agrineoPUBhttps://periodicosonline.uems.br/index.php/agrineo/oaiagriculturaneotropical@uems.br || wellingthon.junnyor@uems.br2358-63032358-6303opendoar:2023-01-18T22:13:40Revista de Agricultura Neotropical - Universidade Estadual de Mato Grosso do Sul (UEMS)false
