Influence of fertilizers on yield and its relationship with the quality of potato stubs in Vologda region

Abstract

In the conditions of the Vologda Region on sod-podzolic soil, the calculated fertilization systems on average for 2015 - 2018 increased the yield of potato tubers by 41 - 66% compared to the minimum dose of fertilizers. The maximum starch content of 12.8% was observed when using an organomineral fertilizer system. The research shows a direct linear relationship between the content of “crude” protein and the yield of potato tubers.
