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%.
Highlights
Potato is the most important agricultural crop for many uses
Results of the 2016-2018 studies have shown that feeding area influenced the biochemical parameters and tasting assessment of Gala tubers and other potato varieties
From the table 1, we observe that the total nitrogen content changed from 0.25 to 0.37% and did not depend on the feeding area
Summary
Potato is the most important agricultural crop for many uses. The varied uses of potatoes are due to their valuable chemical composition. Tubers contain about 25% dry matter, including 10 to 23% starch, 1.4-3.0% high quality proteins, vitamins C, B1, B2, B6, PP and K, which makes it an extremely important product human nutrition. Potato is good food for animals and poultry. In terms of the digestibility of organic matter (83– 97%), it shares the first place with fodder root crops among plant feeds. Potato tubers are raw materials for industrial production of valuable products. Processed products - fresh and dry pulp, bard - are valuable animal feed [16]
