Abstract	The effect of different nitrogen fertilizer rates on the yield and chosen grain quality parameters of selected spring wheat cultivars Napola, Jasna and Kosma, growing under water deficit condition, was studied. The experiment was conducted in a greenhouse in pots containing 6.5 kg of soil with different (from the shooting phase) moisture levels (40 or 60% of full water capacity). The following doses of N were applied: 0.6, 1.2, 2.4 g/pot. Plants were harvested at full ripeness. Water deficiency in soil decreased the grain yield of all cultivars in comparison with the controls (given optimum water condition). In the water deficit conditions in the subsoil the best yielding cultivar was Kosma, independent of nitrogen fertilization. All wheat cultivars reacted favourably to the increase of N rate. The grain yield, protein and gluten content increased together with the increase in N rate applied to the soil. Water deficit favourably affected grain quality parameters of the examined cultivars in comparison to objects with a higher moisture level
