The aim of this study was to precisely quantify the effect of different level and time of nitrogen application on the field and malting quality of spring barley grain of cultivar Prestige. Source of results was the field experiment carried out in 2003-2005. The experiment was carried out with the split-plot method in 4 replications. 8 fertilization combinations were tested (0; 20; 40; 40 (20 + 20); 60; 60 (40 + 20); 80; 80 (60 + 20) kg N·ha^-1). It was found that in soil of the good wheat complex at content N_min. = 55-77 kg·ha^-1 in layer 0-90 cm in spring high grain yields are obtained already at fertilization 40-60 kg N·ha^-1. Considerably higher productivity of these rates is obtained when they were divided into two parts – presowing and that applied at 23 BBCH stage. Raw material of the malting cultivar (Prestige) collected under different conditions of weather (year with average total precipitation and wet year) and fertilization (N rates from 20 to 80 kg N·ha^-1) is characterized by small variability of main qualitative index values of grain, malt and wort and comprehensive Q index according to EBC.
