To obtain higher yields in soybean crops, the use of new products, such as biofertilizers, has been well accepted by producers, whether for soil or foliar application. Thus, the aim of this study was to evaluate the effect of commercial biofertilizers VitaComplex® (based on sugarcane molasses + amino acids) and AminoVita® (based on citric acid, saccharides and animal slaughter residues) on agronomic characters and soybean yield. The products were applied via foliar spray in vegetative and reproductive stages. Plant height, stem diameter, SPAD, leaf organic carbon (C.O) and yield were evaluated. Stem diameter, height, SPAD index and C.O did not show statistically significant differences depending on the doses tested. For productivity, there were gains of up to 1.78 t ha-1, when compared to the control treatment. Both the individual or combined application of the tested products caused increases in soybean yield.
