INOUE, Miriam Hiroko et al. Grain yield and seed quality of soybean after desiccants application. Cienc. Rural [online]. 2003, vol.33, n.4, pp.769-770. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782003000400030.
Herbicides diquat (0.3kg ha-1), paraquat (0.4kg ha-1), amonium-gluphosinate (0.5kg ha-1) and carfentrazone-ethyl (30g ha-1) were sprayed to soybean plants at the R7,5 stage in order to study their influence on soybean grain yield and seed quality. There were no differences among treatments with regard to germination, vigor, seed health, weight of 100 seeds, seed moisture content and seed yield. Nevertheless amonium-gluphosinate and control treatments provided higher percentages of normal seedlings after accelerated aging, compared to the other treatments.
