In the conditions of the right bank of the Saratov region, the responsiveness of sugar sorghum varieties (Kapital, Sahara, Seviliya, Volonter, Chaika) to the application of humic preparations (K-Humate-Na with trace elements, Reasil Forte Carb-N-Humic and Reasil Forte Seed Start) was studied at the experimental field of “Rosorgo”. The aim of the research was to determine the greatest stimulating effect of humic preparations on selection-valuable traits, including seed yield. Pre-sowing treatment of seeds and vegetative plants with K-Humate-N with trace elements (a dose of 1.0 l/t+1.0 l/ha) proved to be the most effective in cultivating Chaika, Kapital and Sahara varieties. Depending on the variety, this allowed an additional 0.94-1.22 t/ha of seeds to be collected. The influence of Reasil Forte Carb-N- Humics (dose 1.0 l/t+2.0 l/ha) on the yield of Seviliya and Volonter varieties was quite high. The use of the drug increased seed productivity by an average of 0.85-0.94 t/ha over two years of testing. Humic preparations had a stimulating effect on the sowing quality of seeds, the length of the panicle and the weight of seeds from a single panicle.
