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.

Vliv dusíkato-sirného hnojiva s inhibitorem nitrifikace na výnos a kvalitu zrna pšenice ozimé

This diploma thesis examines an impact of a nitrogen-sulphur fertilizer with and without a nitrification inhibitor on a yield and quality of a winter wheat grain. From a qualitative feature there has been observed an impact of fertilizers on a volume weight, nitrogen substances, gluten and sedimentation value. The research was conducted in a form of small fields experiment in a business year 2015/2016, 2016/2017 and 2017/2018 in a different localities. The first locality can be found on a South Moravia region specifically at experimental fields of School agricultural enterprise in Žabčice and the second is at Research fodder plants station in Vatín in Vysočina. There has been included five different variants in a research. 1. Unfertilized, 2. CAN + CAN, 3. ANAS + CAN (ammonium nitrate + ammonium sulfate), 4. CAN + ANAS, 5. CAN + ENSIN (ammonium nitrate + ammonium sulfate + inhibitor of nitrification). The results show, that an influence of fertilizer was influenced by a weather conditions in a particular year, when was yield increased in a 2016/2017 by 30 % against a previous year. The yield was also influenced by localities in which has been held. The difference was also between individual variants of fertiliszrs where the variant LAD + ENSIN performed the best with an average yield of 8,18 t/ha. Regarding the qualitative parameters of grain there has been also differences between individual years, localities and also fertiliser variants, however some of the values did not fulfilled norms for a food wheat, so the wheat is in general evaluated as a fodder wheat because the values for the volume weight of winter wheat grain were not met. The economic profit of the research was the best in variant LAD + ENSIN, where were finally displayed transportation savings and amount of applied fertilisers.
