Abstract. Purpose. In 2020–2023, studies were conducted in the experimental field of the State Agrarian University of the Northern Urals to study the effect of the biological drug “Rostok” on the yield and quality of tubers of early-ripening potato varieties Karmen and Praym. Scientific novelty. For the first time, the effect of the biological drug “Rostok” in the conditions of the forest-steppe zone of the Tyumen region was studied on early-ripening Karmen and Praym varieties. Methods. The research used generally accepted methods for potatoes. Results. It was found that the drug “Rostok” accelerated the growth and development of plants of the studied varieties by 1–4 days compared with the control. The damage to potato plants by late blight, bacteriosis, rhizoctoniosis, X and Y viruses in experimental variants decreased by 12–19 %. In the variants with the treatment of tubers before planting, as well as tubers and plants during vegetation, the leaf area was 32.3 and 35.2 thousand m2 /ha for the Karmen variety, 33.7 and 36.8 thousand m2 /ha for the Praym variety. In the control version, it was 26.9 and 28.6 thousand m2 /ha, respectively. Photosynthetic productivity increased from 4.8 g/m2 · day in the control variant of the Karmen variety to 6.1 in the variant with treatment of tubers and plants and from 5.2 to 7.3 g/m2 · day in the Praym variety. The use of the drug “Rostok” on the studied potato varieties accelerated the formation of tuber yields in trial digs. Thus, during the first digging (on July 5), the yield of the Karmen variety in the control version was 7.4 t/ha, in the best experimental versions – 8.9–10.6 t/ha, in the Praym variety – 7.5 and 9.2–10.8 t/ha, respectively. The noted advantage of the experimental variants remained in the subsequent digs. Thus, the use of the drug “Rostok” accelerated and increased the production of early potatoes in the Karmen and Praym varieties in the northern foreststeppe of the Tyumen region. The profitability level was 88–95 %, in the control version – 46–49 %, respectively. The research results open up the possibility of solving the problem of import substitution in potato growing in the Tyumen region.
