EFFECT OF SOIL CULTIVATION METHODS ON PRODUCTIVITY AND QUALITY OF POTATOES OF DIFFERENT VARIETIES IN THE CONDITIONS OF FOREST-STEPPE IN MIDDLE VOLGA REGION

The reaction of new early ripening potatoes of Molly, Red Scarlett and Kolette varieties on the main processing of gray forest soil in the conditions of the forest steppe of the Middle Volga region was studied. The aim of the work is to determine the effectiveness of different soil treatment options. The work was performed on the experimental field of Kazan SAU in 2012-2015. The dumping of plowing at a depth of 20-22 cm was compared with a non-spinning loosening of 26-28 cm and processing of a BDP by 18-20 cm. It was established in the course of research that, without spilling, Molly’s variety, on an average for four years, yielded 36.29 tons per hectare, with the dumping of plowing 35.89 tons per hectare. In similar variants, Red Scarlett formed the yields of 38.66 and 37.96 tons per hectare, and the grade of Kolette - 34.29 and 35.84 tons per hectare. With all methods of soil treatment, more starch contained potato tubers of the Kolette variety. Depending on the variant of soil cultivation, it was 13.73-14.13% in tubers of this variety. Less starch (12.83-13.20%) contained tubers of the Molly variety. Vitamin C and protein was more contained in the tubers of the Red Scarlett variety.
