The objective of this study was to evaluate the growth, development and yield of grains, in order to better understand the behavior of doses of Lumix and Vivat Science products in the vegetative phase of soybean. The experiment developed in the experimentation area belonging to the company Tecno Nutrição Vegetal e Biotecnologia Ltda. The experimental design used was in randomized blocks, with 5 treatments and 4 replications, totaling 20 experimental plots, in the treatments different solutions between the Lumix + Vivat products were tested: T1) Control; T2) Lumix (0.5 L ha-1) + Vivat (0.5 kg ha-1); T3) Lumix (1.0 L ha-1) + Vivat (1.0 kg ha-1); T4) Lumix (1.5 L ha-1) + Vivat (1.5 kg ha-1); T5) Lumix (2.0 L ha-1) + Vivat (2.0 kg ha-1). Chlorophyll contents (Cl a; Cl b; total Cl) were determined and the mass of 100 grains and grain yield were quantified. Physiological and productivity data were identified by an analysis of variance (p < 0.05) and cases of significance were identified by the Tukey mean test (p < 0.05). Biofertilizer substances provided increases in soybean grain yield.
