Experience using organomineral fertilizer on potatoes

Relevance. Potatoes are one of the most important food crops in the Russian Federation and CIS countries. For the normal growth and development of the potato plant, it is necessary to provide sufficient nutrition elements. The modern direction is the selection of drugs based on natural sources that improve the mineral nutrition of plants and meet environmental requirements, which is relevant.Methods. Determination of the effectiveness of the use of organomineral fertilizer Adgelar for foliar top dressing of potato tubers. The objects of the study were potatoes of the Salsa variety and the organomineral fertilizer Adgelar. The experiment was carried out on gray forest soil.Results. It was revealed that foliar fertilization with Adgelar fertilizer contributed to increasing yields and improving the quality of potato tubers of the Salsa variety. The increase in potato yield was 17.5% at a dose of 0.3 l/ ha, 23.2% at a dose of 0.75 l/ha, 31.0% at a dose of 1.2 l/ha. With the use of fertilizer, the number of tubers increased (from 1 m²) by 16 17.8%, the average mass of commercial tubers (from 1 m²) – by 16.3–34.8% compared to the control. The share of the seed fraction of tubers increased by 1.5–6.2%, food – by 1.1–3.2%. The starch content in the dry matter increased (by 8.2–11%). There was a decrease in vitamin C by 7–18% compared to the control. In the variants with fertilizer in doses of 0.3 l/ha and 1.2 l/ha, nitrate nitrogen was higher by 10 and 49 mg, respectively.
