摘要

The article presents experimental data on yield, yield structure and quality of seed potatoes of the varieties Skarbnitsa, Levada and Yav?r, depending on fertilizer and treatment with growth regulators Emistim S, Regoplant and Stimpo. On average, over three years of research, the enrichment of N45P45K45 and N90P90K90 increased the yield on 5.45 and 7.09 t ha-1 (37 and 48%). With background nutrition N45P45K45, growth regulators increased yields from 3.6% to 21.7%, depending on the variety and regulator. Fertilizers and growth regulators increased the dry matter content in tubers on 0.8 and 1.1%, starch - on 0.4 and 0.9%. Due to the use of fertilizers, the content of vitamin C decreased on 3.9 and 7.4%, nitrates increased on 30.1 and 60.4%. The maximum productivity of the early variety Skarbnitsa and medium early Levada was formed with the combined use of mineral fertilizers in a dose of N45P45K45 with the Regoplant growth regulator treatment - 21.85 and 22.12 t ha-1 . When growing a mid-season variety Yavir, there was a need to use a dose of N90P90K90 fertilizers without growth regulator treatment, the yield was 22,65 t ha-1 .
