Abstract

Research was conducted in 2013-2016. on the experimental field of the Northern Autonomous Urals SAU in the area of the Instructional Farm. The soil is leached chernozem, heavy loam in particle size, moderately supplied with nutrients, ph-6,7. The study of the mineral nutrition level in early varieties of potatoes Alyona and Severny showed that it is economically advantageous to make mineral fertilizers for a planned yield of 30 and 40 t / ha, which is combined with the quality of tubers. A further increase in the mineral nutrition level increases the yield, but economically it is not profitable. Potato harvest, obtained in variants with high doses of mineral fertilizers, is stored worse than in the control version. Considering the yield and quality of the tubers of the studied potato varieties, it is economically advantageous to apply mineral fertilizers for a yield of 30-40 t / ha. Considering the yield and quality of the tubers of the studied potato varieties, it is economically advantageous to apply mineral fertilizers for a yield of 30-40 t / ha. At the same time, the level of profitability was 86 and 104%, respectively, for comparison in the control variant - 54-59%. A further increase in the level of mineral nutrition in the cultivation of early potato varieties Alyona and Severny is not economically viable
