Export-oriented intensification of potato production in the central non-chernozem region of Russia

The results of studies (2019-2020) in a two-factor field experiment on sod-podzolic light-loamy well-cultivated soil the study effect non-root fertilization productivity potato varieties are presented. following factors were studied: A – Variety: 1 - Colomba, 2 Red Scarlett, 3 Gala. B Preparation for foliar dressing: Control (water, 300 l/ha), Zircon (30 ml/ha), Epin-Extra (15 4 Folirus Premium (7 5 Aquamix (220 g/ha), 6 Mixture Zn-EDDA + Cu EDDA complexates l/ha). It was revealed that Scarlett variety had highest productivity. Methods have been developed to increase by using growth regulator Zircon, which provides yield dry matter and starch (an 19.3 18.9 % control), fertilizers mixture 14.4 11.8 control).
