Resumo: This study aimed to evaluate the sweet corn cob characteristics under different levels of nitrogen fertilization and irrigation depths in two cropping seasons in northeastern region of Mato Grosso do Sul, Brazil. The experiment was conducted in of split plot scheme, having in the plots four irrigation depths (50, 75, 100 and 125% of crop evapotranspiration-ETc) and in the subplots, four nitrogen rates (0, 100, 200 and 300 kg ha-1) and in the sub-subplots, two cropping seasons (Winter/Spring and Summer/Autumn), in the randomized blocks design with four replication. The following characteristics were evaluated: straw number, ear length, ear diameter, kernels number per row, rows number, cob diameter, grain length, grains number and ear weight. Sweet corn showed higher ear quality at the Summer/Autumn season and was not affected by nitrogen fertilization. At the time Winter/Spring season, sweet corn should be irrigated with replacement of 85% of ETc, while in Summer/Autumn season with 50% ETc.

O experimento foi conduzido em parcelas subsubdivididas, tendo nas parcelas quatro lâminas de irrigação (50, 75, 100 e 125% da evapotranspiração da cultura - ETc), nas subparcelas quatro doses de nitrogênio em cobertura (0, 100, 200 e 300 kg ha-1) e nas sub-subparcelas duas épocas de cultivo (Inverno/Primavera e Verão/Outono), no delineamento em blocos casualizados, com quatro repetições. Foram avaliadas as características: número de palha por espiga, comprimento de espiga, diâmetro de espiga, número de grãos por fileira, número de fileiras por espiga, diâmetro de sabugo, comprimento de grão, número de grãos por espiga e peso de espiga. O milho doce apresentou maior qualidade de espiga na época Verão/Outono e não foi afetado pela adubação nitrogenada. Na época Inverno/Primavera, o milho doce deve ser irrigado com reposição de 85% da ETc, enquanto que no Verão/Outono, com 50% da ETc.Universidade Federal de Viçosa - UFV2016-05-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/55810.13083/reveng.v24i1.617Engineering in Agriculture; Vol. 24 No. 1 (2016); 50-62Revista Engenharia na Agricultura - REVENG; v. 24 n. 1 (2016); 50-622175-68131414-398410.13083/reveng.v24i1reponame:Engenharia na Agriculturainstname:Universidade Federal de Viçosa (UFV)instacron:UFVporhttps://periodicos.ufv.br/reveng/article/view/558/381Souza, Epitácio José deCunha, Fernando França daMagalhães, Fernando FagnerSilva, Thiago Ramos daSantos, Osvaldir Feliciano dosinfo:eu-repo/semantics/openAccess2023-01-19T13:25:15Zoai:ojs.periodicos.ufv.br:article/558Revistahttps://periodicos.ufv.br/revengPUBhttps://periodicos.ufv.br/reveng/oairevistaengenharianagricultura@gmail.com||andrerosa@ufv.br||tramitacao.reveng@gmail.com|| reveng@ufv.br2175-68131414-3984opendoar:2023-01-19T13:25:15Engenharia na Agricultura - Universidade Federal de Viçosa (UFV)false
