The diploma thesis is focused on the evaluation of the influence of graded nitrogen nutrition of spring barley on the production of yield elements, grain yield and its quality by targeted application of non-root nutrition – ListerMo, which currently regulates content of nitrogen substances in grain. The small-lot field trial was based on the grounds of Agrospol Velká Bystřice. After emergence, N-fertilizers were applied at doses of N1 - 80 kg N.ha-1, N2 - 110 kg N.ha-1 and N3 - 140 kg N.ha-1. ListerMo was applied in three different phases of BBCH (25, 30, 45 - 50) during vegetation. Grain yield was comparable at N1 and N2, higher N dose reduced grain yield. Reduced grain yield reflects the effect of lower ears quantity per m2. The effect of ListerMo has been shown to reduce N-content most when applied to BBCH 30.
