The comparision of winter wheat grain yield and quality
CIRHAN, Radek
Thesis topic: Assessment of wheat yield and quality. Three conventional varieties (Midas, Genius and Papageno) and one hybrid variety (Hyland) were subject to the test. The test was carried out in operational conditions of an agricultural plant in 2014. The assessed Midas and Genius varieties are classified as elite varieties in terms of baking quality and the Papageno variety and the hybrid Hyland variety are classified as unsuitable for dough production. The test was aimed at the assessment of the main yield elements, i.e. the number of spikes per m2, the number of grains per spike and the weight of a thousand grains. Another assessment parameter was the quality of grains of the assessed varieties.

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.

The quality and use of naked oats
FIŠER, Martin
The purpose of this bachelor´s thesis was summary of new knowledge about qualitative properties and possibilities of utilization of naked oats varieties and their comparison with hulled oat varieties. Naked oast excels especially in its high nutritional and energy value, in the content of essential amino acids, in high content of fats, vitamins and minerals and theirs high biological value together. These factors classify naked oats between the important components of foodstuffs for human need and between the important components of fodder for livestock too. The health significance is essential for grains of naked oat in foodstuffs and in food supplements. Naked oats finds using in many other branches of industry than in grocery only, naked oats is used, for example, in cosmetic industry, in pharmaceutical industry, in floristry possibly too. Relatively low yields of grains are balanced by a long-term, higher purchase prices which makes naked oats a strategic crop from economic aspect.
