Resumo: The objective of this research was to evaluate the influence of Diquat herbicide application, at different periods, on production and physiological quality of bean seeds, cultivar: Perola. The experimental design used was a randomized block (RBD). The treatments were constituted of application of such herbicide with dosage of 400 g ai / ha in eight stages of application (83, 85, 87, 89, 91, 93 and 95 days after seeding (DAS) and without application with 97 days – witness .) The analyzed variables were moisture content (%), germination (%), first count of germination (%)velocity index of germination, seedling emergence (%), initial stand (%)velocity index of emergency, thousand seed weight (g) and production (kg ha-1). The moisture content of the bean seeds at the times of herbicide application declined, anticipating up to 14 days to harvest beans. For the first counting and germination no difference was observed between treatments. But for the IVG observed superior results at 83 DAS. For emergence percentage and EVI the values were lower at 87 and 89 DAS. On the other hand, the data obtained for the initial stand did not differ. For the thousand seed weight and production results were superior to 89 DAS and at 89 and 95 DAS, respectively. The application of Diquat desiccant in bean crop from 83 days after sowing did not affect the germination of the seeds, however, affect significantly the production of seeds.

O delineamento experimental utilizado foi de blocos casualizados (DBC). Os tratamentos constituíram da aplicação do herbicida com dosagem de 400 g i.a./ha, em oito estádios de aplicação (83, 85, 87, 89, 91, 93 e 95 dias após a semeadura (DAS) e sem aplicação aos 97 dias – testemunha). As variáveis analisadas foram, grau de umidade (%), germinação (%), primeira contagem da germinação (%), índice de velocidade de germinação, emergência de plântulas (%), estande inicial (%), índice de velocidade de emergência, peso de mil sementes (g) e produção (Kg ha-1). O grau de umidade das sementes de feijão nas épocas de aplicação do herbicida decresceram, antecipando em ate 14 dias a colheita do feijão. Pela germinação e primeira contagem não foi observado diferença entre os tratamentos. Já para o IVG observou-se resultados superiores aos 83 DAS. Para a porcentagem de emergência e IVE os valores foram inferiores aos 87 e 89 DAS. Em contrapartida, os dados obtidos para o estande inicial não diferiram entre si. Para o peso de mil sementes e produção os resultados foram superiores aos 89 DAS e aos 89 e 95 DAS, respectivamente. A aplicação do dessecante Diquat na cultura do feijoeiro a partir dos 83 dias após a semeadura não afeta a germinação das sementes, porém, reduz de maneira significativa a produção de sementes.UEL2013-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1023410.5433/1679-0359.2013v34n4p1707Semina: Ciências Agrárias; Vol. 34 No. 4 (2013); 1707-1714Semina: Ciências Agrárias; v. 34 n. 4 (2013); 1707-17141679-03591676-546Xreponame:Semina.
