This thesis examined the effects of applied stabilized nitrogenous fertilizers with sulphur (ENSIN and ENTEC 26) and nitrogenous fertilizers without inhibitors (DASA) in the nutrition of winter wheat. The effect of various forms of stabilized nitrogenous fertilizers on the yield and qualitative parameters of winter wheat was studied during a three-year vegetative experiment. The experiment was carried out in the form of a small plot experiment in two localities (Žabčice near Brna and Vatín near Žďáru nad Sázavou). The experiment included the following six variants of fertilisation: 1. unfertilised control, 2. DASA + DASA (ammonium nitrate and ammonium sulphate) , 3. ENSIN, 4. ENTEC 26, 5. LAD (ammonium nitrate with dolomite) + ENSIN, 6. LAD + ENTEC 26. On all fertilized variants there was a significant increase in yeald compared to the unfertilized control (an average of 22.4 to 37.3 %). The highest average yield for three years amounted variant LAD + ENSIN in the locality Vatín and Žabčice. The maximum average yield 7,39 t/ha reached the option LAD + ENSIN in the locality Vatín and 7,61 t/ha in the locality Žabčice. This variant also achieved the highest content of N - substances and sedimentation value. Only in bulk density was better option LAD + ENTEC 26, however, there was no significant difference. Variant LAD + ENSIN was effective also in terms of economic efficiency.
