DEUNER, Cristiane et al. Yield and quality of soybean seeds produced under different nutritional managements. Rev. de Ciências Agrárias [online]. 2015, vol.38, n.3, pp.357-365. ISSN 0871-018X.

Soybean has great economic importance in Brazilian agriculture and the productivity and the profitability are key aspects. The employ of seeds with high germination and vigor associated with fertilizer availability and rates is very important to achieve an adequate plant stand, high yield and quality of seeds. In this context, this study aimed to evaluate the effect of the fertilization management through seed treatment and foliar application on yield components and physiological quality of soybean seeds. The experimental design was a randomized block with four replications and six treatments, composing by a control and five different nutrient combinations (CoMo, Complet, Phosphorous Potassium, Manganese and CaB). These combinations were applied through seed treatment or foliar at different times. Considering the set of agronomic traits the treatment 2 is the most efficient technically. Seed produced under the treatment 4 showed physiological quality inferior to the other, considering the variables analyzed.
