The aim of research is to study the influence of natural regulators Mival–Agro, KRP, Megafol, Zh and Ecopin, TPS on the growth processes, yield and quality of potato varieties Vympel and Krasa Meshchery during the preparation of planting material and the treatment of plants during their growth and development. The objects of research were two mid-season potato varieties: Vympel, Krasa Meshchery and three growth regulators: Mival-Agro, KPR; Megafol, Zh; Ecopin, TPS. Experimental design: 1 – control (tubers and plants without treatment); 2 – Megafol, Zh (tubers – 4 ml/t, plants – 0.4 ml/ha); 3 – Mival-Agro, KPR (tubers – 2 g/t, plants – 20 g/ha); 4 – Ecopin, TPS (tubers – 0.1 kg/t, plants – 0.3 kg/ha). A study of the effectiveness of plant growth regulators (Mival-Agro, KRP; Megafol, Zh; Ecopin, TPS) on the Vympel and Krasa Meshchery potato varieties demonstrated their positive impact on plant growth, development, yield, and product quality. The use of Megafol, Zh, and Ecopin, TPS, also stimulated bud germination, reaching 77.6 and 72.4 % for Vympel potatoes, and 76.9 and 70.4 % for Krasa Meshchery potatoes, respectively. Field germination of the studied potato varieties increased by 3.8–5.6 % compared to the control group. The use of the Mival-Agro growth regulator, KRP, resulted in the maximum yield compared to the control variant: Vympel – 38.7 c/ha (+18.2 %), Krasa Meshchery – 36.3 c/ha (+17.8 %). The use of the Megafol, Zh, and Ecopin, TPS growth regulators also contributed to the increase in the yield of the two varieties, but to a lesser extent: Vympel – 30.6 (+14.4 %) and 30.2 c/ha (+14.2 %); Krasa Meshchery – 27.8 (+13.7 %) and 26.7 c/ha (+13.1 %), respectively.
