On options 2 and 3, the density is the highest, 48.9 and 45.7 thousand bushes/ha, respectively. The highest rate was noted on variants 2 and 3, respectively 4.0 (194.5 thousand pcs./ha) and 4.1 (189.6 thousand pcs./ha) per plant. The highest indicators of the leaf surface area were also established on variants 2 and 3, respectively 282.6 and 244.0 cm2, which is more than the control variant by 65.5 and 26.9 cm2. In the Myroslav variety, during the first planting period, the average density is 47.2 thousand bushes/ha. The highest density was set on variants 2 and 3, respectively, 48.0 thousand bushes/ha, which compared to the control one is 2.5 thousand bushes/ha. The highest indicators of the leaf surface area were set on variants 2 and 3, respectively 307.4 and 301.9 cm2, which is more than the control variant by 45.6 and 40.1 cm2 On average, over three years of research, the yield of seed tubers in the Radomysl variety was 34.2 - 47.3%, in the Myroslava variety 34.2 - 40.3%, the weight of the tubers was 8.6 and 12.1 t/ha, respectively, according to the multiplication factor 4.4-4.7 in the Radomysl variety and 3.0-4.9 in the Myroslava variety. According to the results of the 2021-2023 research, both in the Radomysl variety and in the Myroslava variety, options 2 and 3 turned out to be the most cost-effective. In general, a positive effect of the use of the complex biopreparation Fitosubtil and the antistress Intra Cell® on the biometric indicators of the development of potato plants and its yield was established.
