In current agriculture, the use of biostimulant products has become a viable and economical option for high yields and improvements in product quality. Although few studies have addressed the effect of biostimulants on biometric aspects. Therefore, the objective of this study was to evaluate the use of biostimulants, isolated and combined, in the agronomic performance of Glycine max (L.) plants. The experiment was conducted in a greenhouse at the Federal University of Tocantins, Gurupi-TO. The treatments consisted of three biostimulants (BU-RG, BU-EC and BU-VG) used in three ways applications (via seed, foliar and combined). The experimental design was a randomized block design, with four replications. The following characteristics were evaluated; seedlings height, stem diameter, leaf dry mass, dry stem mass, root dry mass and root system volume. The biostimulant BU-EC applied via seed showed the highest growth rate in height of seedlings. The combination of the BU-RG biostimulants via seed + BU-VG via leaf, promoted the highest rate of leaf dry mass accumulation. In the variable dry mass of the root, the treatment BU-RG via seed + BU-EC via foliar promoted the greater increase. The treatments BU-VG2 and BU-RG1 + BU-VG2 provide an increase in plant height, greater root dry mass production and root system volume increase both in seed and leaf application.
