Description
Summary:ABSTRACT The purpose of this study was to evaluate the effect of the chemical treatment with fungicide, insecticide, micronutrient and polymer on physiological and sanitary quality of soybean seeds during storage. The treatments were arranged in a 3 x 5 x 5 factorial scheme (cultivars x seeds treatment x storage period), in completely randomized design with four replicates. Three cultivars were used: NA 4823RG, BMX TurboRR and Fundacep 62RR. The treatments were: T1: no chemical treatment, T2: fungicide, insecticide and micronutrient; T3: fungicide, insecticide, micronutrient and polymer, T4: fungicide; T5: insecticide. After the chemical treatment, the seeds were stored under environmental conditions from May to December 2012, and seed quality was evaluated at 0, 2, 4, 6 and 8 months of storage. Seeds water content and physiological quality were determined through tests of germination, accelerated aging, seedling length, seedling dry weight and sanity. The treatment with fungicides, insecticides, micronutrients and polymer did not affect seed quality over eight months of storage and promoted the control fungi associated with the seeds.
