 During the years of research in 2021-2023, the highest yield of seed tubers was established for 3 variants of potato removal in varieties: Opillya - 11t/ha, Radomysl - 10.5t/ha, Vzirets - 10.7t/ha, Bazaliya - 11.2t/ha , Syngaivka 13.7t/ha. Removal of potatoes in the 2nd variant provided an average weight of one tuber in varieties of 22-35g. with a tuber mass of 41-61 g in the control, in this case the decrease was 53.0-57.3%. In the variant with the removal of potatoes 20 days after flowering, the average weight of one tuber was, depending on the potato variety, in the range of 35-57 grams. or a decrease in tuber weight relative to the control by 8.5-9.3%. A high yield of tubers from one hectare of the sown area was obtained by removing potato plants in the first term (10 days after flowering), which was 455,000 units/ha for Opillya, 439,000 units/ha for Radomysl, and 464,000 units/ha for Vzirets. , Bazaliya 406 thousand units/ha, Syngaivka 521 thousand units/ha. The yield of the ultra-early variety Radomysl in variants 2-4 was 18.7, 17.2 and 19.6 t/ha, which is 2.6, 1.1 and 3.5 t/ha more than the control variant – 16.1 t/ha ha, in the mid-early variety Myroslav 18.4, 18.9 and 20.2 t/ha, which is 2.6, 3.1 and 4.4 t/ha more than the control variant – 15.8 t/ha. The seed productivity of plantations increased by 11.2-13.0% in the options where treatment of tubers before planting and plants during the growing season was applied, from 2021-2023 it was within the range of 40.1-68.7% under control of 24.2- -25.7%. During the reporting period, in all variants and varieties, the mass share of tubers of the large fraction was within 48.2-70.1% under control of 22.3-24.3% of the total mass of tubers, from 2021-2023 it was within 40.1 -68.7%, on control 24.2-25.7%.
