|Description:||The industrial treatment of seeds has favored the development of new technologies such as the use of dry powder. It has made application of spray volumes higher than those used in the conventional treatment. Therefore, this study aimed to assess the effect of industrial treatments at different spray volumes with and without application of dry powder on physiological quality of soybean seeds. A completely randomized experimental design was performed with four replications in a 5 x 2 factorial arrangement for cultivars BRS 359 RR and BRS 284. The factors were five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg-1) with and without the application of dry powder. The products used to obtain the volumes were fungicides (carbendazim + thiram); insecticides (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulant (kinetin + gibberellic acid + 4-indol-3-ylbutyric acid) and inoculant (Bradyrhizobium japonicum). The physiological quality of the seeds was determined by the following assessments: germination, first count of germination test, seedling emergence in sand, emergence speed index, and total length of the seedling shoot and root. The results showed that increased spray volume associated with the application of dry powder in seed treatment reduced the physiological quality of soybean seeds, and spray volumes up to 1200 mL 100 kg-1 in seed treatment without the application of dry powder do not impact the emergence and establishment of soybean seedlings.|
