Monitoring of the wheat quality for food production
Slavíčková, Radka ; Hýsková, Eva (referee) ; Omelková, Jiřina (advisor)
The aim of this study was to monitor the quality of wheat Triticum aestivum, imported into the laboratory MORAGRO after harvest by eight different suppliers, and to evaluate the main quality parameters decisive for the final use of cereal crops. The introduction of the theoretical part was devoted to understanding commercial and agricultural importance of wheat and description of morphological and physiological characteristics of wheat grain. The core of the theoretical part has been focused on the description and explanation of physical and chemical properties of the wheat grain, which largely affect the final product quality of wheat. External factors affecting final quality and yields of wheat were also commented. The experimental part was based on measurements of main quality parameters of wheat (moisture content, bulk density, falling number, amount of gluten and the wheat proteins, sedimentation value and content of additives and impurities). In most cases, measurements were carried out using automated instruments. The quality of wheat was determined based on the obtained results, which allows deciding, whether it is appropriating for food production.

Porovnání působení dusíkato-fosforečných hnojiv ve výživě pšenice ozimé a řepky ozimé
Večeřa, Radomír
The aim of the diploma thesis was to assess and compare the effect of spring nitrogen-phosphorus fertilization on the yield and qualitative parameters of winter wheat and winter oilseed rape. Small-plot experiments took place at Vatín in 2020/2021 and 2021/2022. The experimental variants of fertilization for both model crops were 1. Control, 2. NPS immunMax (12-10+11S), 3. GSH NP 15-5+20S, 4. CAN + Amofos (12-52) (3:1) and 5. CAN + Amofos (12-52) (1:1). The parameters used in the assessment of winter wheat were yield, bulk density, nitrogenous substances and wet gluten content, grain sedimentation value. Winter oilseed rape were assessed by observing the yield and the oil content of the seeds. Winter wheat was monitored for the influence of the two terms of application of NP fertilizers during tillering. Winter oilseed rape was monitored for the influence of fertilization with a 100% dose of N and the application of NP fertilizers during side-shoot formation stage and fertilization with a dose of 70% N and the application of NP fertilizers in begin of stem elongation. The weather in individual years of the experiment had a statistically significant effect on the yield and quality parameters of winter wheat. There were no significant differences between the variants of NP fertilization and the terms of spring application. In the case of winter oilseed rape, the effect of the weather in years of the experiment was proven only for the yield. There was no significant difference between the variants of NP fertilization. A significant effect on yield and oil content was proven between terms of application with different doses of N. In the long term, phosphorus fertilizing in the spring make sense due to low phosphorus content in soil or ensure the return of phosphorus taken by harvests, but no yield or quality effect was recorded during the two-year observation.
