Vrtěl, Petr
The aim of this bachelor thesis was to evaluate the efficiency of autumn fertilization technology with stabilized nitrogen-sulfur fertilizer (ENSIN) in oilseed rape. The experiment was established in the economical year 2014/2015 in the form of a small-plot field experiment on the fields of the School farm in Žabčice. Evaluation criterions were seed yield and oil contend of oilseed rape. The following variants of the ENSIN fertilizer application were included in the experiment: variant 1 in the autumn was not fertilized, variant 2 was in the autumn fertilized, variant 3 fertilized in the autumn later and variant 4 fertilized in autumn later and in spring at the beginning of elongation . The variants of fertilization were statistically inconclusive in seed yield and oil contend. Highest yield had variant 4.

Využití dusíkatého hnojiva s inhibitorem nitrifikace ve výživě pšenice ozimé
Vícha, Lukáš
The aim of this bachelor's thesis is to assess the influence of nitrogen-sulphurous fertilizer with an inhibitor of nitrification (ENSIN) on the yield, nutrition and quality of winter wheat grain. The experiment was carried out on a small parcel in the locality of Žabčice u Brna (184 metres above sea) level in farming season of 2015/2016). The experiment involved five variants: 1. LAD (checking), 2. DASA 26-13, 3. ENSIN, 4. LAD + DASA 26-13 a 5. LAD + ENSIN. The date of application was also taken into consideration. The differences in the yields and bulk density in different variants were not significant. The option: LAD + ENSIN reached the highest average yield and bulk density. The differences in quality of the grain of the variants were statistically significant. The highest reading for N-substances, content of gluten and sedimentation was also at the variant LAD + ENSIN. On the other hand the worst results were provided by the variant ENSIN. It can be stated that later application of the fertilizer ENSIS to winter wheat is more useful.

Působení aplikace hnojiv na bázi síranu amonného na výnos a olejnatost semen řepky ozimé
Vrtěl, Petr
This thesis follow up influence of fertilization on yield and oil content of oilseed rape (Brassica napus L.). There were used fertilizers based on ammonium sulfate in the regeneration (BBCH 26, spring) and production fertilization (BBCH 31) during vegetation phase of oilseed rape. The issue was solved as a two-year small-plot field experiment carried out in the vegetation seasons 2016/2017 and 2017/2018 at the Field Experimental Station in Žabčice. The following variants were included in the experiment: Control (CAN), Ammonium sulfate (AS), Ammonium sulfate with boron (AS + B), Ammonium sulfate with nitrification inhibitor (AS + IN). Each fertilization variant was applied either as regenerative fertilization (BBCH 26) or first production fertilization (BBCH 31). The yield of seeds and also their oil content was significantly influenced by the vegetation season. Yield in the vegetation season 2017/2018 were higher by 41 % than in the vegetation season 2016/2017 because of weather conditions. The oil content was higher by 4 % in the vegetation season 2017/2018. The yield of seeds and also their oil content were not significantly influenced by the fertilization variant or by the vegetation phase of application. The highest average yield 4,23 t/ha was variant Control. The Control also was the highest average oil content of 40,2 %. High temperatures during both years reduced the efficiency of nitrification inhibitor. Fertilization with a boron-containing fertilizer had no effect because of drought and pH.

David, Petr
The bachelor thesis examines the influence of stabilised nitrogenous fertilizers on yield of grain and qualitative characteristics of winter wheat. The experiment was solved in year 2017/2018 in two locations. These locations were in Žabčice near Brno and Vatín near Žďár nad Sázavou. The experiment contained five following variants: 1. LAD (amonium nitrate with dolomite) + LAD + UAN (ammonium nitrate with urea), 2. LAD + UAN, 3. LAD + UAN + IN (nitrification inhibitor), 4. LAD +UAN + IU (urease inhibitor), 5. LAD + UAN + IN + IU. Variants of locations and fertilization had not statistically significant effect on the yield of grain, content of N-substances and sedimentation value. The highest yield of grain reached variant LAD + UAN with 8,93 t/ha. The highest content of N-substances was reached on Žabčice’s variant LAD + LAD + UAN with 16,5 %. This variant achieved the highest sedimentation value too. It was 60 cm3. Variants with inhibitors in Žabčice did not reached higher values than variants without inhibitors on observed parameters because of heat and drought. In Vatín were more successful variants with inhibitors specifically variant LAD + UAN + IU on all observed parameters.

Ovlivnění výnosu a kvality pšenice ozimé použitím stabilizovaných dusíkatých hnojiv se sírou
Minařík, Petr
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.

Stabilizované močoviny ve výživě pšenice ozimé
Ruška, David
The aim was to assess the effects of stabilized ureas on the nutritional status of winter wheat crop during the growing season, yield of grain and the qualitative characteristics of grain - bulk density, the content of N-substances, gluten content and sedimentation value. The results were then compared with the non-fertilized variant and with the variant with fertilizers without inhibitors. The experiment was conducted in the form of a small-parcel field trial at ŠZP in Žabčice in the farming year 2012/2013. Examined were the effects of seven following variants: 1. unfertilized variant, 2. fertilizer LAD applied in two dose, 3. urea applied in two doses, 4. urea applied in one dose, 5. fertilizer with urease inhibitor UREA Stabil, 6. urea with nitrification inhibitor ALZON 46, 7. combination of fertilizers ALZON 46 and UREA Stabil in ratio 1:1. The effects of fertilized variants on values of N-tester clearly dominate. Similarly, this applies also for the content of N-substances, gluten content and sedimentation value. In case of the yield, the results were not so clear. Between the highest and the lowest value (unfertilized variant) the difference was approximately 1 t/ha. Demonstrated was only the positive effect of nitrogen fertilization on increase of grain yield. The values for bulk density are very similar for all variants. Effects of all nitrogen fertilizers on the given characteristics were very balanced. Slightly better results were reached for fertilizers ALZON 46 and ALZON 46 with UREA Stabil (1:1).

This thesis examined the effectsof applied stabilized fertilizers with nitrogen and sulphur content of mineral nitrogen and sulfurin the soil at two experimental sites. Further, the effect of each variant of fertilizers on yield and oil content of winter oilseed rape. The problem was solid by form of small-plot field trial at the experimental sites Žabčice and Vatínin the marketing year 2012/2013. The experiment included the following variants of fertilization: 1. unfertilized, 2. ENSIN 100 % of the dose, 3. ENSIN 80 % of the dose, 4. ENTEC 26 100 % of the dose, 5. ENTEC 26 to 80 % of the dose, 6. DASA+DASA, 7. LAD (ammonium nitrate with dolomite) + ENSIN. Fertilizers ENSIN and ENTEC 26 containing DASA (ammonium nitrate and amonium sulphate) and nitrification inhibitor. For variants 2 and 4 was applied once the total dose of nitrogen (194 kg / ha) and variants 3 and 5 was applied, only 80 % of the dose (155 kg / ha) as a stage tillering fertilization. Variant 6 was fertilised by DASA without a nitrification inhibitor. DASA was applied (78 kg / ha of nitrogen) as a regenerative fertilization, as well as the of fertilization I. (58 kg /ha of nitrogen). For the production of fertilization II. was used fertilizer DAM-390 (150 kg /ha of nitrogen). Seventh variant combines Ammonium nitrate (78 kg / ha of nitrogen) is applied as a restorative fertilization and stabilized fertilizer ENSIN (116 kg / ha of nitrogen), which was applied as fertilizer production I. The experimental area was Žabčice Nmi content and Lead in soil at the beginning of stem elongation highest in the variant fertilized fertilizer ENTEC 26 100 % dose. The seed yield of winter oilseed rape had different variants of fertilization statistically significant effect. Oiliness was statistically lower in the variant ENSIN 100 %, ENTEC 26 % 80 and DASA + DASA. The greatest economic efficiency, option fertilization LAD + ENSIN. This variant 1 crown costs fertilization produces 3.63 crowns in seed yield. The experimental area Vatín the highest content of Nmin in the soil at the beginning of stem elongationon the variant fertilizing ENTEC 26 100 % dose. The seed yield of winter oilseed rape is statistically different only from the other variant fertilized variant, which was applied fertilizer. The oil content of the parameter is statistically different each variant of fertilization. After evaluating various options coefficient of efficiency was the most effective fertilizer ENSIN 80 % of the dose. This variant 1 crown fertilizer cosi creates seed yield 7.39 CZK.

Tržil, Marek
The aim was to compare the effects of stabilized ureas including sulphur (in different dosing) with fertilizers without inhibitors on nutrition of winter wheat crop. There were a five differential variants: 1. ALZON 46 (urea with inhibitor of nitrification) + ammonium sulfate (1:1), 100% dose, 2. ALZON 46 (urea with inhibitor of nitrification) + ammonium sulfate (1:1) 80% dose, 3. ALZON 25 -- 6 S, 100% dose (fertilizer with nitrification inhibitor involving 25 % nitrogen and 6 % sulphur) 4. ALZON 25 -- 6S, 80% dose, 5. Urea + ammonium sulfate. I examine the effects of these variants on nutrition of crop, yield and qualitative characteristics of grain. The experiment was realized on small-parcel field at ŠZP in Žabčice in year 2012/2013. The variant ALZON 25 -- 6 S 80% dose reached the worst results for the gluten content, content of N-substances and sedimentation value. The variant Urea + ammonium sulfate had the lowliest value of a bulk density. The best results were reached for fertilizer ALZON 46 (urea with inhibitor of nitrification) + ammonium sulfate in ratio 1:1 (100 % dose) for parameters such as value of N-tester, yield of grain, sedimentation value, content of N-substances and gluten content.

Dusíkato-sirná hnojiva s inhibitory nitrifikace ve výživě pšenice ozimé
Minařík, Petr
This work examines the influence of nitrogen-sulfur fertilisers with nitrification inhibitors in winter wheat nutrition. We esteblished small-plot experiment in the test-field station of School Farm in Žabčice near Brno in the agricultural year 2012/2013. The experiment included six variants of fertilisation: 1. unfertilised control, 2. ENSIN 100% (DASA with inhibitor nitrification), 3. ENSIN 80%, 4. ENTEC 26 100%, 5. ENTEC 26 80%, 6. DASA + DASA (ammonium nitrate + ammonium sulfur). Fertilisers with inhibitors were applied in the stage of tillering at dose 140 kg nitrogen per ha, respectively, 120 kg nitrogen per ha for the variant with 80% of the dose. DASA fertiliser was applied in two divided doses. We evaluated the effect of fertilisation on the yield and the grain quality parameters. Statistically significant was the effect of fertilised variant to N-tester. The highest results were obtained for variant DASA + DASA. Fertilisation was not significant influence for yield and grain volume, but the highest yield and grain volume was achieved in variant ENTEC 26 80%. The fertilisation has statistically significant effect on content of N-substances in the grain. The highest average content of N-substances reached variant DASA + DASA, which has 28% higher N substances content compared to unfertilised variant. Between gluten content and sedimentation value in the fertilised variant were found significant differences. The highest gluten content and sedimentation value were found in variant DASA + DASA.
