The purpose of this research was the evaluation of the influence of chelate compounds of micronutrients on yield and state tubers of mid-season potato variety Kolobok during storage. The research was conducted on the fields with sod-podzolic sandy loam soil in 2016 and 2017 years. During the research one tuber processing and two foliar processing were done before planting and during vegetation respectively. The experiment had two control groups, the first group was not treated at all and the second group was treated with water. The organization of field experiment, counting and observation were done according to requirements of methods of field experiment and “Methods of investigation of potato varieties”. On average two years groups treated with drugs, which contain chelate compounds of micronutrients, had 4.4 and 4.7 main stems per bush respectively that was more than in control groups. The application of the drugs increased marketable yield by 3.5–3.7 t/ha (13.5–14.2 %). On average two years groups treated with the sulfur-containing drug had the biggest marketable yield that was 9.9 tubers per bush (1.5 tubers per bush or 17 % more than the first control group). The obtained result of the experiment means that these drugs are worth using during potato cultivation.
