This scientific article analyzes the effect of biostimulants (Fitobiosol, Gumi-20, Avangard Start) on the leaf area development of mung bean cultivars. The study was conducted during the phases of the 4th true leaf, flowering, and pod formation, with leaf area measurements compared to the control variant. The biostimulant Avangard Start demonstrated the highest efficiency, increasing leaf area by 8.9–31.1% depending on the cultivar. The results confirm that the use of biostimulants is a significant factor in enhancing the photosynthetic activity of plants and increasing crop yield.
