Resumo: | Information about the effect of herbicides on cowpea seed quality is scarce. The objective of this work was to evaluate the effect of using chemical desiccants at pre-harvest on the anticipation of harvest and physiological quality of cowpea seeds of the cultivar BRS-Tumucumaque, before and after storage. Two experiments were conducted: experiment 1 was conducted under a randomized block design, with four replications; the treatments consisted of seven herbicides (carfentrazone-ethyl, saflufenacil, glyphosate, paraquat, flumioxazin, glufosinate-ammonium, and diquat) and a control treatment; anticipation of harvest, and seed water content, germination, and vigor were evaluated. The seeds were stored for six months in controlled environment and not-controlled environment rooms and evaluated for water content, germination, and vigor in Experiment 2, which was conducted in a 7×2+1 factorial arrangement, with four replications; the first factor consisted of the seven herbicides, the second factor was the two storage environments, plus a control treatment. The results showed 3 to 9 days of anticipation of harvest relative to the control. The glufosinate-ammonium herbicide negatively affected seed germination and vigor. The glyphosate herbicide decreased seed germination and vigor after storage. The physiological quality of cowpea seeds at the post-harvest period and after six months of storage was not affected by the carfentrazone-ethyl and flumioxazin herbicides. Paraquat and diquat were the most efficient herbicides for the anticipation of harvest (nine days). Glyphosate and glufosinate-ammonium were the most harmful herbicides to seed physiological quality. The controlled environment room was the most adequate environment for seed conservation. |

Objetivou-se avaliar o efeito de dessecantes químicos na pré-colheita sobre a antecipação da colheita e qualidade fisiológica das sementes de feijão-caupi Cv BRS Tumucumaque, antes e após o armazenamento. No experimento 1, adotou-se o delineamento de blocos casualizados, com quatro repetições. Os tratamentos foram: sete herbicidas (carfentrazone-ethyl, saflufenacil, glyphosate, paraquat, flumioxazin, amonio-glufosinate e diquat) e um tratamento controle. Avaliou-se a antecipação de colheita, teor de água, germinação e vigor das sementes. As sementes foram armazenadas por seis meses em sala climatizada e ambiente não controlado e avaliadas quanto ao o teor de água, germinação e vigor, compondo o experimento 2, que foi disposto em esquema fatorial 7x2+1, com quatro repetições. O primeiro fator correspondeu a sete herbicidas, o segundo a dois ambientes de armazenamento, mais um tratamento controle. Observou-se um período de 3 a 9 dias de antecipação da colheita em relação a testemunha. O amônio-glufosinate afeta negativamente a germinação e o vigor das sementes. Após o armazenamento, menor germinação e vigor foram observados para o herbicida glyphosate. Os herbicidas carfentrazone-ethyl e flumioxazin não afetaram a qualidade fisiológica das sementes de feijão caupi nos períodos pós-colheita e seis meses após o armazenamento. O paraquat e o diquat foram os herbicidas mais eficientes na antecipação da colheita (nove dias). O glyphosate e o amonio-glufosinate foram os herbicidas mais prejudiciais à qualidade fisiológica das sementes. A sala climatizada é o ambiente mais adequado para conservação das sementes.
