The purpose of the study was to assess the impact of innovative drugs: sulfur-containing and microelements in chelated form: iron, zinc, manganese, copper, molybdenum, cobalt, boron, on the yield and quality of potato tubers of medium ripe variety Kolobok. The research was carried out in 2016-2017 on sod-podzolic sandy loamy soil. The field experience, records and observations were made in accordance with the requirements of the field experience methodology and the Potato Culture Research Methodology. On average, over two years, the use of the preparation with S content in chelate form increased the yield by 3.7 t/ha (14.2 %). Application of the preparation with the content of trace elements Fe, Zn, Mn, Cu, Mo, Ko, B in chelate form - by 3.5 t/ha (13.5 %). The content of nitrates on the variants with the use of sulfur-containing preparation was 201 mg/kg; the content of the preparation with trace elements was 230 at 245 mg/kg on the control variants. The lowest darkening of raw pulp on a scale of nine points was found on variants with S - 6.83 points (+1.83 or +36.6 %). On variants with the use of the preparation containing microelements, the average value of darkening of raw pulp of tubers was 6.75 points (+1.75 or +35.0 %). Tubers of the variant with the use of the preparation with S - 6.25 points turned out to be tastier. The data obtained may be of interest to specialists growing potatoes for industrial processing, for example, for mashed potatoes, vacuuming of peeled raw potatoes.
