The objective of this paper was to evaluate seed coating of soybean seed using equipment for treatment with spray system Grazmec®. The treatments applied with the equipment were: 1) control, 2) fungicide, 3) amino acid, 4) polymer, 5) fungicide + amino acid, 6) fungicide + insecticide, 7) fungicide + polymer, 8) fungicide + insecticide + polymer, 9) fungicide + amino acid + insecticide. The evaluation of the spray system was followed by moisture content determination, weight of 1000 seeds and coverage. Also field emergence was evaluated. The seed quality evaluations were followed by germination, vigor, dry matter of plants and seed health. The seeds were storage for six months and evaluations were done every 60 days. The results sh...
