ADUBAÇÃO FOLIAR COM ESTIMULANTE DE CRESCIMENTO NA CULTURA DE SOJA INFLUENCIA NA PRODUÇÃO E QUALIDADE DAS SEMENTES?

Abstract

The use of high quality soybean seeds has been the major difference in the successful establishment of the crop, where the high vigor of the seeds provides a significant increase in production. Producing excellent seeds and increasing production performance is an ideal to be achieved. Therefore, this work aimed to evaluate the influence of foliar fertilization with a growth stimulant on the production and quality of soybean seeds. The experiment was conducted in two stages, one in the field and the other in the Seed Analysis Laboratory (LAS). Both locations belonging to IF Goiano – Campus Iporá, located at Fazenda Escola. The soybean cultivar managed was M6410 IPRO, four treatments were tested consisting of: Control 0 = (no application), application of 500 ml ha-1 of Aggressive Desperta (Amino acids) in: T1 = in the reproductive phenological stage (R1); T2 = combined application in both stages (R1 + R4) and T3 = in the reproductive phenological stage (R4). In the field, plant performance, yield and productivity components were evaluated. At LAS, assessments of the physiological quality of the seeds were carried out. The seeds were also sown in the field to evaluate seedling performance. The R1+R4 treatment provided greater quality and vigor to the soybean seeds and contributed to increased crop productivity.
