| Background: The use of desiccant herbicides can allow the anticipation of common bean harvesting by providing a reduction in the humidity of plants and grains. Objective: Determine the effect of doses of desiccant herbicides on the moisture content of the plants (stems, leaves and grains), in the 100 grains mass, grain yield and physiological quality of the seeds of two contrasting common bean cultivars. Methods: The experimental design for each cultivar (BRS FC 104, super early cycle, 60 days from sowing to harvesting and BRS Estilo, normal cycle, 90 days from sowing to harvesting) as in randomized blocks in the factorial scheme 4 x 3 x 4, with four replications. Treatments consisted of four herbicides (ammonium glufosinate (200 g L-1 of active... |

| ABSTRACT: Pre-harvest desiccation is an important strategy to anticipate harvesting, preventing the seed from being left in the field in unfavorable climatic conditions. However, little is known about the use of desiccants and their application times on cowpea (Vigna unguiculata). The objective of this study was to evaluate the effect of desiccant application at different seasons and of desiccant herbicides on productivity and physiological quality of cowpea seeds. Five dessicants were evaluated: paraquat, paraquat sequential application, glufosinate- ammonium, glyphosate with sequential application of paraquat and paraquat + diuron mixture applied in four seasons: 50% of the pods with green coloration and with seeds formed (season I); 70% of the pods in... |
