Within a four-year small plot field trials, the effect of nitrogen fertilizers containing added sulphur on selected quality characteristics of the barley grain and malt was tested. The combination of a lower N dose (30 kg/ha) and S increased the grain yield by 0.2-0.34 t/ha and when the N applied alongside S was higher (50 kg/ha), the grain yield rose by 0.1-0.2 t/ha. S application had a positive effect on grain quality. S combined with a lower level of N led to the highest yield of the malting grain (92.5-94.2%) and stabilized the starch content in the barley grain. The S addition did not lead to an increase of N-substances in the grain; neither did it increase the PDMS content in malt when higher doses of N were applied.
