Ekonomické zhodnocení účinku vybraných hnojiv se stabilizovaným dusíkem u pšenice ozimé

The aim of submitted thesis was to evaluate the application of selected fertilizers with nitrogen and sulfur to the grain yield and the quality of winter wheat production and the impact of their use on the economy of this cereal crop. Their testing was carried out in a one-year field experiment. In the experiment selected combinations of fertilizers containing various forms of N, N-fertilizers with sulfur and manure added with nitrogen conversion inhibitors were tested. Fertilizers were applied in selected terms of regeneration, production and quality fertilization. At a total ration of 159 kg/ha N. N-fertilizer with urease inhibitors and nitrification inhibitor – Urea Stabil and Alzon Neo – achieved the best results. Their application increased the yield (Alzon Neo) and consequently the economy of wheat growing technology (Urea Stabil). A decrease in the results of the experiment was recorded for sulfur-containing fertilizers (Ensin and DASA). Low yield effect was found after application of LAD + LAD + DAM 390 fertilization. Wheat food quality E was achieved in all fertilization variants tested. In the variant using a uniform application of fertilizer with urease inhibitor (Urea Stabil), the economy of the growing technology generated up to 37 % rel
