Tratamento Industrial de sementes de soja e seus reflexos na qualidade durante o período de armazenamento

Abstract

The soybean seed treatment is an economically recommended technique to protect the seeds against biotic and abiotic factors that can decrease their physiological quality and genetic. This study aimed to analyze the seeds quality and vigor after being submitted to different seed treatment recipes and slurry volume. The experiment was done using soybean seeds of Variety NK7059RR. The seed treatment, germination test, accelerated aging test and emergence were set at the Seed Lab of Syngenta Seedcare Institute in Holambra-SP. Eleven seed treatment recipes were performed and analyzed statistically using completely randomized arrangement with factorial design 11 x 6. The treatments were: T1-untreated seeds; T2-Maxim Advanced + Cruiser 350FS + FloRite 1197; T3-Maxim Advanced + Cruiser 350FS + Avicta 500FS + FloRite 1197; T4-Maxim Advanced + Cruiser 350FS + Stimulate + FloRite 1197; T5- Maxim Advanced + Cruiser 350FS + Avicta 500FS + Stimulate + FloRite 1197; T6- Maxim Advanced + Cruiser 350FS + Booster Agrichem + FloRite 1197; T7-Maxim Advanced + Cruiser 350FS + Avicta 500FS + Booster Agrichem + FloRite 1197; T8- Maxim Advanced + Cruiser 350FS + Avicta 500FS + Booster Agrichem + Stimulate + FloRite 1197; T9-Maxim Advanced + Cruiser 350FS + Água; T10-Maxim Advanced + Cruiser 350FS + Água; T11-Stimulate + Booster Agrichem. The seeds physiological quality can be affected by high slurry volumes applied as seed treatment. Overall the germination were above 80%, proving that it is possible to treat and storage soybean seeds up to 180 days before sowing. It is also possible recommend mixtures of products tested in this study, with slurry volume up to 1200ml / 100Kg seeds whereas from seeds batch with high standards of quality and vigor.
