Potato growing plays a decisive role in ensuring food security in the North-East, as a stable base aimed at using internal reserves in order to increase efficiency and self-sufficiency. The adverse weather events during the growing season, manifested by drizzling fog, permafrost, early frosts, as well as high losses arising from the poor phytosanitary condition of the main crops, lead to large crop losses, which in turn cannot but affect the potato price growth on the market in the Magadan region. To solve this problem, potato culture research is constantly being conducted on the basis of the Magadan Research Institute, based on biologized technology aimed at preserving and increasing soil fertility and crop yields. In the course of breeding research in the extreme conditions of the North-East, varieties were obtained – biological foundation: Zoya, Kolymskiy, Arktika. The varieties combine economically valuable indicators: high plasticity, yield, commodity and table qualities of tubers, keeping quality and resistance to diseases. Special attention is paid to the study of new agrotechnical techniques using raw materials of the Far East, which have proven their effectiveness in increasing the yield and quality of potatoes. In the conditions of the Magadan region, three natural components were tested: seawater, algae, reindeer lichen as a pre-planting treatment of tubers. Optimal parameters were established that had a positive effect in the production of high-quality tubers and an increase of potato yield.
