Two potato varieties varying in the maturity earliness — very early Frezja cv. and very late San cv. were used in the three-year field studies on the effect of nitrogen fertilization. The dynamics of the N. P and K nutrients intake was investigated in the tubers and the stalks in various moments of vegetation. The results of the studies demonstrated differences in the dynamics of the nutrients intake. The components were fixed in the tubers and the stalks of both varieties in various amounts. A decrease in the percentage of the nutrients in the stalks was effectively compensated by an increase in their concentration in the tubers. The effect of fertilization at the rate 120 kg N/ha was manifested mainly as an increase in the intake of all the nutrients. Despite earlier decaying of the stalks, the aggregated intake of the components was increasing generally till the very end of vegetation. A linear increase of the yield was noted for both varieties during vegetation, as caused by nitrogen applied in the amount 120 kg N/ha.
