Abstract: The aim of the study was to determine the effect of herbicides on the yield of various soybean varieties. The study analyzed the following soybean varieties: «FARTA», «SK Optima», and «SK Veda». The experiment was conducted in the Koshekhablsky district of the Republic of Adygea on leached chernozems, using the newly regionalized variety FARTA, under the following treatments: control (no herbicides); Frontier Optima, EC (STANDARD RATE); Basagran SL; Harmony Pro; Panthera, EC; Frontier Optima, EC + Basagran SL; Frontier Optima, EC + Harmony Pro; Frontier Optima, EC + Panthera, EC. After soybean emergence, the first assessment of herbicide effectiveness was carried out at the 1st trifoliate leaf stage, where it was found that the effect of individual herbicides varied from 92.2% to 93.7% over the years of the study. The combined application of herbicides increased their effectiveness by 3.3% to 4.8%. The research established that by the pod formation stage, soybean plants could compete with weeds, and their quantity decreased in the treatment with Frontier Optima, EC - 1.2 l/ha by -1.9%, Basagran SL - 3.0 l/ha by -1.6%, Harmony Pro - 8.0 g/ha by -1.5%, Panthera, EC - 1.5 l/ha by -1.8%. Their combined application increased the competitive ability of soybean plants and significantly reduced the number of weeds when counted per unit area. The results obtained provide a basis for formulating recommendations for the optimal use of herbicides in soybean crops on chernozems in the Republic of Adygea, taking into account economic and environmental factors.
