The use of high quality seeds allows access to genetic advances, with guarantees of quality and adaptation technologies in the various producing regions. The factors that influence seed quality can occur during the production phase in the field, during harvesting, drying, processing, storage, transport and sowing. Quality control must therefore be established, which includes analysing and certifying the seed in order to guarantee the genetic purity of the cultivars, thus assuring the farmer of a pure batch with high vigour, which can establish a uniform stand in the field. The quality of soya bean seed is essential for obtaining an adequate plant stand, because when the seed is placed in the soil to germinate and emerge, it usually encounters adverse conditions of humidity and temperature, among other factors. Considering the importance of seed for agricultural production and aiming to achieve higher levels of profitability, this study will present data on the physical and physiological quality of soya bean seeds from the 2017/2018 harvest in northern Rio Grande do Sul.
