Abstract: The high production levels achieved in soybean cultivation are due to advances in management and technology applied throughout the development of the crop. In this scenario, the use of silicon in soybean plants has gained prominence in recent decades, due to its beneficial properties for plant development and resistance to abiotic stresses. Therefore, the present work aimed to evaluate the use of silicon doses in the treatment of soybean seeds, quantifying germination, vigor, normal and abnormal plants, hard seeds, dead seeds, aerial part and root system. The experiment was installed and conducted in August 2024 at the Seed Research and Analysis Center Laboratory, located on Campus I of the Centro Universitário de Patos de Minas (UNIPAM), in the municipality of Patos de Minas – MG. 250 seeds were selected per treatment and were subsequently weighed so that the weight could be measured. Then the seeds were treated with the product Sifol Power according to the doses: (T1-0); (T2- 100); (T3- 200); (T4- 300) and (T5- 400), mL 100Kg-1 of seed. To assemble the plots, 50 seeds were used per sheet of germitest paper. The experimental design used was completely randomized (DIC), with five treatments and five replications each. Germination, non-germinated seeds, normal and abnormal seeds, hard and dead seeds and length of the shoot and root were evaluated. The results obtained were then subjected to analysis of variance (ANAVA) and the Tukey test at 5%. Among the variables analyzed, the number of germinated, non-germinated, normal, abnormal, hard and dead seeds showed no statistical difference between treatments. However, for the variables root length and shoot length, the treatments differed from each other, with the treatment without applications presenting the highest averages. The use of silicate may not have expressed its full potential due to application via seed treatment (TS), this is justified because most applications with silicon are made via foliar, when the plants already have the size and structure for silicon metabolism. It is concluded, therefore, that the use of silicon doses in seed treatment did not influence the parameters evaluated. Although it was significant for root and shoot length.
