The experiment was conducted in the years 2014–2016 with the aim to evaluate the influence of a biostimulant based on seaweed and amino acids on the content of neutral and acid detergent fiber, lignin, cellulose and hemicellulose in three cultivars of soybean. In the vegetative season, 0.7% and 1.0% solutions of the biostimulant were used in single and double spraying. Based on the determined fiber fraction contents it was evaluated whether treating soybean with the biostimulant may enhance the quality of forages obtained from it. It was found that the level of fiber fractions and contents of hemicellulose and cellulose were influenced by biostimulant application. Differences in the content of fiber fractions resulted from the number of biostimulant doses and its concentration. Mavka cultivar treated with Fylloton was characterized by the highest mean content of fiber fraction. Evaluation of the forage quality indexes demonstrated that biostimulant use caused their reduction, and the highest values were found for Annushka cultivar.
