Biochemical composition of potato tubers of various varieties and the economic efficiency of its cultivation in the conditions of the Middle Urals

Abstract

The purpose of the research is to study the effect of the feeding area of Gala potato, the use of fungicides on the yield and quality of tubers in the Middle Urals. This research was carried out on the experimental field of the educational and experimental farm “Uralets” of the Ural State Agrarian University, the village “Studencheskiy”, during 2016-2018, in the climatic zone of the Middle Urals. The feeding area influenced the mineral and biochemical composition of tubers, especially the content of nitrogen, phosphorus, potassium, dry matter, vitamin C and others. The calculation of the economic efficiency of potato showed that during the years of research, the production cost fluctuated within the range of 4446 - 9446 rubles/ton, the profit from 63 724 to 269 172 rubles/ha and the level of profitability in the range of 24.66-165.43%.
