• Abstract:

  This study evaluated the effects of different polymer formulations associated with micronutrients and inoculants in the treatment of soybean seeds (Glycine max L. Merrill), aiming to understand their influence on germination, initial growth, and root development of seedlings. The experiment was conducted in a greenhouse at the State University of Goiás, Palmeiras de Goiás Unit, in the first semester of 2025. The experimental design was randomized blocks, with seven treatments and thirty-six replicates (each plant being one replicate). Germination parameters, length, and fresh and dry mass of the aerial part and root system were evaluated, in addition to nodulation. The data were submitted to analysis of variance (ANOVA) and the means were compared by the Scott-Knott test at a 5% probability, using the AgroStat® program. The results showed significant differences between treatments, with T6 (Polymer + Experimental CoMo – 100) standing out, as it performed better in terms of root length and mass, in addition to promoting greater initial vigor. The association between polymers and micronutrients (Co and Mo) proved to be efficient for root growth and initial nutrition, although nodulation was reduced or absent in most treatments. It is concluded that the use of polymers associated with micronutrients represents a promising strategy for improving soybean seed treatment, although the compatibility between polymer and inoculant should be carefully evaluated.
