Resumo: Irrigation and nitrogen fertilization are management practices that have positive results for the corn crop. This study aimed at evaluating the effect of nitrogen fertilization and irrigation on agronomic traits of sweet corn. Two experiments were carried out in two crop seasons (winter/spring and summer/autumn), in a split-plot design, with the main plots consisting of four irrigation levels (50 %, 75 %, 100 % and 125 % of the crop evapotranspiration - ETc) and subplots consisting of four nitrogen doses (0 kg ha-1, 100 kg ha-1, 200 kg ha-1 and 300 kg ha-1), applied at the V3 and V8 stages, via urea, in a randomized blocks design experiment, with four replications. Leaf nitrogen content, root depth, plant height, stem diameter, ear yield and water use efficiency were evaluated. In the winter/spring season, nitrogen fertilization did not affect yield, while in the summer/autumn season the dose that maximized yield was 300 kg ha-1. Sweet corn showed better results when irrigated with replacements of 50 % and 125 % of ETc, respectively in the summer/autumn and winter/spring seasons.

Objetivou-se avaliar o efeito da adubação nitrogenada em cobertura e lâminas de irrigação sobre as características agronômicas de milho doce. Dois experimentos foram conduzidos em duas épocas de cultivo (inverno/primavera e verão/outono), em parcelas subdivididas, tendo-se nas parcelas quatro lâminas de irrigação (50 %, 75 %, 100 % e 125 % da evapotranspiração da cultura - ETc) e nas subparcelas quatro doses de nitrogênio em cobertura (0 kg ha-1, 100 kg ha-1, 200 kg ha-1 e 300 kg ha-1), aplicadas nos estádios V3 e V8, via ureia, em delineamento em blocos casualizados, com quatro repetições. Foram avaliados o teor de nitrogênio foliar, profundidade de raízes, altura de planta, diâmetro de colmo, produtividade de espigas e eficiência do uso da água. No inverno/primavera, a adubação nitrogenada não afetou a produtividade, enquanto, no verão/outono, a dose que maximizou a produtividade foi de 300 kg ha-1. O milho doce apresentou melhores resultados quando irrigado com reposições de 50 % e 125 % da ETc, respectivamente no verão/outono e inverno/primavera.Escola de Agronomia - Universidade Federal de Goiás2015-09-09info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/33628Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 3, Jul./Sep. 2015; 282-290Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 3, jul./set. 2015; 282-290Pesquisa Agropecuária Tropical; v. 45, n. 3, jul./set. 2015; 282-2901983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/33628/18970Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessSouza, Epitácio José deCunha, Fernando França daMagalhães, Fernando FagnerSilva, Thiago Ramos daSantos, Osvaldir Feliciano dos2020-07-13T16:24:25Zoai:ojs.revistas.ufg.br:article/33628Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:08.102416Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
