Resumo: | The cowpea plays an important role in the Brazilian agricultural production, especially in the North and Northeast Regions, where it is widely cultivated by smallholders. Thus, this study aimed at evaluating the physiological quality of cowpea seeds produced under no-tillage and conventional tillage and different periods without irrigation. A randomized blocks design, in a split-plot scheme, with four replications, was used. The plots consisted of cropping systems (no-tillage and conventional tillage), while the subplots consisted of periods without irrigation (2, 6, 10, 14, 18 and 22 days). In the plots, seeds were collected and subjected to the following evaluations: seeds weight per plant, one thousand seeds weight, test weight, seed length and width, moisture content, germination, accelerated aging, field seedling emergence and emergence speed index. Cowpea seeds from plants subjected to hydric stress resulted in lower physiological quality, but were physically bigger and heavier. The no-tillage system provided seeds with better physiological quality. Cowpea plants subjected to hydric stress after flowering produced fewer seeds. |

Neste sentido, este trabalho foi desenvolvido com o objetivo de avaliar a qualidade fisiológica de sementes de feijão-caupi produzidas em sistema plantio direto e convencional, sob diferentes períodos sem irrigação. Utilizou-se delineamento em blocos casualizados, em esquema de parcelas subdivididas, com quatro repetições. As parcelas foram constituídas por sistemas de plantio (direto e convencional) e as subparcelas por períodos sem irrigação (2, 6, 10, 14, 18 e 22 dias). Nas parcelas, as sementes foram colhidas e submetidas às seguintes avaliações: massa de sementes por planta, massa de mil sementes, massa hectolítrica, comprimento e largura da semente, grau de umidade, germinação, envelhecimento acelerado, emergência de plântulas em campo e índice de velocidade de emergência. Sementes de feijão-caupi provenientes de plantas submetidas ao estresse hídrico resultaram em menor qualidade fisiológica, contudo, fisicamente maiores e mais pesadas. O sistema plantio direto proporcionou sementes com melhor qualidade fisiológica. Plantas de feijão-caupi submetidas ao estresse hídrico após o florescimento produziram menor quantidade de sementes.Escola de Agronomia - Universidade Federal de Goiás2013-11-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/22226Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 43, n. 4, Oct./Dec. 2013; 370-376Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 43, n. 4, out./dez. 2013; 370-376Pesquisa Agropecuária Tropical; v. 43, n. 4, out./dez. 2013; 370-3761983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/22226/15514Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessFreitas, Rômulo Magno Oliveira deTorres, Salvador BarrosNogueira, Narjara WalessaLeal, Caio César PereiraFarias, Raul Martins de2020-07-10T12:51:38Zoai:ojs.revistas.ufg.br:article/22226Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:59.684701Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
