Resumo: Cowpea has been cultivated in a rudimentary form in the main producing regions of Brazil, resulting in lower grain yields, when compared to the crop potential. The use of technologies such as water regimes, adequate plant density and soil management are alternatives to increase this crop yield. This study aimed at evaluating the effects of different water regimes and plant densities on the yield components of cowpea cultivated under conventional and no-tillage systems. A randomized block design in a split-plot factorial, with four replications, was used. The treatments consisted of five water regimes in the plots (157.00 mm, 189.00 mm, 234.00 mm, 274.00 mm and 320.00 mm) and five plant densities as subplots (12 plants m-2, 16 plants m-2, 20 plants m-2, 24 plants m-2 and 28 plants m-2). The evaluated variables were: number of pods per plant, number of pods per area, pod length and grain yield. The combination between 270 mm of irrigation water depth with a density of 280,000 plants ha-1 resulted in higher grain yield using the no-tillage system, while the combination between the density of 280,000 plants ha-1 and 320 mm of water depth favored the highest grain yields in the conventional growing system.

A utilização de tecnologias como regimes hídricos, densidade de plantas e manejo adequado do solo são alternativas para aumentar os rendimentos dessa cultura. Objetivou-se avaliar os efeitos de regimes hídricos e densidades de plantas sobre os componentes de produção e produtividade de feijão-caupi, em sistemas de cultivo convencional e direto. Utilizou-se delineamento em blocos casualizados, em parcelas subdivididas, com quatro repetições. Os tratamentos foram cinco regimes hídricos nas parcelas (157,00 mm; 189,00 mm; 234,00 mm; 274,00 mm; 320,00 mm) e cinco densidades de plantas como subparcelas (12 plantas m-2, 16 plantas m-2, 20 plantas m-2, 24 plantas m-2 e 28 plantas m-2). As variáveis analisadas foram: número de vagens por planta, número de vagens por área, comprimento de vagens e produtividade de grãos. A combinação entre a lâmina de irrigação de 270 mm e a densidade de 280.000 plantas ha-1 promoveu maiores ganhos na produtividade de grãos no plantio direto, enquanto a combinação entre a densidade de 280.000 plantas ha-1 e a lâmina de 320 mm favoreceu os melhores rendimentos da produtividade de grãosno plantio convencional.Escola de Agronomia - Universidade Federal de Goiás2018-01-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/47908Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 47, n. 4, Oct./Dec. 2017; 432-439Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 47, n. 4, out./dez. 2017; 432-439Pesquisa Agropecuária Tropical; v. 47, n. 4, out./dez. 2017; 432-4391983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/47908/25040Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessMonteiro, Marinete Martins de SousaBastos, Edson AlvesCardoso, Milton JoséAndrade Júnior, Aderson Soares deRibeiro, Valdenir Queiroz2020-07-13T18:53:20Zoai:ojs.revistas.ufg.br:article/47908Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:17.666473Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
