The purpose of the research was to evaluate the effectiveness of the technology of remote electromagnetic processing of potato varieties by weak non-ionizing pulsed alternating electromagnetic fields (EMF). Potato tubers (varieties of domestic local selection Pechorsky and Zyryanets) before planting were subjected to electromagnetic exposure using the TOR-bio apparatus, in the 15/5 mode (15 minutes of exposure, 5 minutes break for 1 hour before planting) with an individual spectrum of exposure. Evaluation of the effectiveness of EMF on the yield of potatoes was carried out at the sites of the Institute of Agrobiotechnology of the Federal Research Center of the Komi Scientific Center of the Ural Branch of the Russian Academy of Sciences. The area of the experimental plots was 800 m². Potato planting (0.7 × 0.3 m), as well as field observations of potato plants, were carried out according to the standard generally accepted methodology. The soil of the experimental plot is soddy-podzolic. Soil analyzes were carried in certified analytical laboratories. Pre-planting treatment of tubers with EMF (results of 2021 and 2022 studies) led to a significant increase in overall crop compared to control options. Under the conditions of the Komi Republic, varieties of local selection turned out to be more EMF-sensitive. A multiple reduction in losses of potatoes laid down for long-term storage has been proven with automated daily short-term remote processing using the TOR technology of storage facilities by reducing the pathogenic load. The proportion of tubers affected by scab during winter storage (November 2021 to March 2022) in processed potatoes was 5% versus 14% in the control (untreated) group. In 2022, three weeks after potato harvesting, the decrease in processed potatoes did not exceed 2% (1.9%), in the control variant it was 9%, in potatoes grown on a plot prepared for growing crops, the decrease was 5.5%. The loss of weight due to the dry sleeve for the storage period from November 2022 to April 2023 for processed potatoes was 0.6%, unprocessed – 0.95%. The proportion of tubers infected with scab in processed potatoes was 6%, in unprocessed potatoes – 13%.

Key words: solanaceous crops; potatoes, weak electromagnetic fields; weak electromagnetic radiation; yield, storage.
