APPLICATION OF BIO-STIMULANT AND NUTRIENT COMPLEX IN THE TREATMENT OF SOYBEAN SEEDS

Abstract

               New technologies have been employed to maximize plant production for soybean (Glycine max L.).Thus, the objective of this study was to evaluate the influence of seed treatment with bio stimulants and supplementation with nutrient complexes in order to improve emergence percentage and increase initial soybean growth. The experiments were carried out in laboratory and greenhouse at “Faculdade Católica do Tocantins”, Campus of Agricultural and Environmental Sciences in Palmas - TO. Treatments consisted of: T1 - Seed treatment with Stimulate product (phytoregulator products), T2 - (macro and micronutrient based), T3 - combined application (Stimulate® + Raiz^®) and T4 - untreated (Witness), with five repetitions for each

 treatment. The germination percentage (%) and the root length (cm) and hypocotyl (cm) evaluations were evaluated at the eighth day of implementation of the laboratory and greenhouse experiment. cm), root length (cm), stem diameter (mm), dry mass of aerial part (g) and root dry mass (g) at 41 days. Data were subjected to analysis of variance (F test) and Tukey's test at 5% probability. There was no significant difference in germination percentage, hypocotyl length, plant height, root length and dry mass of aerial part. Results showed that in laboratory evaluations, the combined application of Stimulate^® + Raiz^® positively influenced root length. Likewise, for greenhouses evaluations, the treatments with Stimulate^® and the combined application of Stimulate^®+ Root positively influenced the stem diameter and root dry matter, respectively.
