This article presents an assessment of domestic and imported potato varieties’ productivity and chemical dynamics during their vegetation under natural conditions on meadow-chernozem soils of Irtysh river area in Western Siberia. This research aims to determine optimal nitrogen and phosphorus content in potato leaves during the plant’s flowering. It is notable that nitrogen and phosphorus dynamics in potato plants on different stages of development are mostly characterizing potato species rather than potato varieties, while crop yield rates reflect mostly varietal differences. In this research, different potato varieties have been assessed by their resistance to unbalanced conditions and nitrogen deficiency.
