Transport and thermophysical data for thermic sanitation calculation of agricultural seeds
Vávra, Dan ; Brummer, Vladimír (referee) ; Juřena, Tomáš (advisor)
The bachelor's thesis focuses on properties that are important for thermal sanitation. Commonly used seed treatment methods are summarized in the theoretical part. Furthermore, seeds‘ transport and thermo–physical properties are written out and described. To the present day, the properties of wheat seeds have been determined, while there are fewer publications for pea seeds. The available properties were determined by research for wheat and pea seeds. Furthermore, the experimental procedures for obtaining wheat properties were verified and then the procedures were applied to pea seeds. In the experiments, values were obtained for porosity, bulk density, true density, static angle of repose and specific heat capacity for certain humidity. The results are written out with total measurement uncertainties. The values of properties were discussed.
The use of humine preparations at the winter wheat
ŠVEC, Jakub
The diploma thesis deals with the use of humic preparations in winter wheat (Tri-ticum aestivum). The experiment was based on a family farm with two varieties of winter wheat. These were varieties from the Lima Grain company. The varieties were LG Mocca and LG Magirus. In the experiment, 3 different dosage variants of Blackjak were compared against the control variant. The dose of the product was graduated in half a liter per hectare, i.e. variant No. 1: 0.5 l*ha-1, No. 2: 1 l*ha-1, No. 3: 1.5 l*ha-1. In the case of the LG Mocca variety, there was an increase in profits in all variants, from which it can be concluded that even the application of 0.5 l*ha-1 is advantageous. However, the highest increase in profits was for variant No. 3, where the increase in profits was CZK 3,087. For the LG Magirus variety, these results were not so clear. Variant No. 1, where 0.5 l*ha-1 was applied, came out with a lower profit than the control variant. The highest increase in profits was for variant No. 3, where the increase was CZK 1,554.
Využití vybraných komponentů rostlinného původu ve výživě ryb
Zugárková, Iveta
The main aim of this Bachelor´s thesis was to create a literary review on the use of selected plant components in fish nutrition. Part of the review contains data on fish bre-eding and nutrition, nutritional requirements regarding the nutrients and customization of fish food. The second part of the Bachelor´s thesis presents a draft on the methodo-logy of a feeding test. Both scaled and mirror forms of common carp (Cyprinus carpio L.) will be used in this test and fed different crops: feeding and low-phosphate wheat, feeding and pearl barley. The corps will be processed into granule to make the food intake and utilization easier. The test will star in May 2016 and be carried out in the recirculation system of the aquarium room at the Department of fishery and hydrobiolo-gy of the Mendel University in Brno. The aims of the test is to evaluate the production effectiveness of used crops, including their influence on the chemical composition of fish tissues and selected parameters of internal environment of fish bodies. The tested crop species were chosen based on the data on the influence of various crops on the phosphorus level reductions in fishponds. Because the plant food for carp represents the most expensive part of carp breeding, there is ongoing research for finding economically and nutritionally suitable food.
Průnik obsahu mykotoxinů ze zrna obilovin do hotového výrobku a dopad na zdraví člověka
Machálková, Monika
This thesis deals with the issue of mycotoxins, which are important pathogens of many agricultural crops and may pose a high health risk to humans and livestock. It contains an overview of the most important mycotoxins their producers and mycotoxicoses. The main focus of this thesis is the occurrence of mycotoxins in cereals and the effect of processing it on their content. The experimental part focuses on monitoring the content and the penetration of deoxynivalenol and zearalenone in winter wheat from grain to bread. We examined a total of 10 samples of treated and 10 samples of untreated variants of winter wheat. For each sample grain, flour and bread were examined for DON and ZEA content and all tested samples were positive for DON and ZEA. None of the examined samples exceeded or even approached the legislative limits.
Nákladově-produkční vztahy v zemědělském podniku
Ležovičová, Lucia
The thesis is focused on analysis of economical factors in connection with particular farming products produced by selected agricultural company in given years. The analysis includes calculation of cost, revenue and profit indicators, connected with profitability and productivity of producing factors. It includes evaluation of cost-production optimum in short term.
Winter wheat growing in terms of selected farms
PAUL, Radim
The goal of the bachelor thesis was to establish and evaluate a pilot experiment. The effect of 3 nutritional variants with a graded dosage of nitrogen and the application of a growth regulator with the active substance trinexapac-ethyl on the yield and quality parameters of winter wheat grain was evaluated. There was 145 kg pure nutrient N*ha-1 of growth regulator in scenario 1, 191 kg pure nutrient N*ha-1 in scenario 2 and 191 kg pure nutrient N*ha-1 with applied growth regulator in scenario 3. The experiment was performed on a family farm in the growing season of the year 2018 and 2019 near the village Dobkov by the town Chotěboř. The actual yield was in scenarios 2 and 3 was only slightly increased (in the order of tens of kilograms) in spite of the higher dosage of nitrogen in scenario 2 and the application of a growth regulator in scenario 3. Both the higher dosage of nitrogen and the addition of growth regulator had a positive effect on yield-forming elements, and increased the number of ears per m2, further reducing the average number of grains in a spike in scenarios 2 and 3. The weight of one thousand grains was positively affected by a higher dosage of nitrogen in scenario 2, but negatively affected in scenario 3. All quality parameters (nitrogen content, gluten content, Zeleny test and bulk mass) were positively affected by a higher dosage of nitrogen in scenario 2. The application of the growth regulator in scenario 3 increased the declining trend, the Zeleny test, the gluten content, the nitrogen content and also negatively affected the bulk mass.
ILCA for selected cereal species
The aim of this work was to identify and evaluate the environmental burden that arises during the cultivation of wheat and rye. The categories of agrotechnical operations, field emissions, fertilizers and pesticides were compared. The subsequent goal was to compare the resulting environmental burden between conventional and organic farming.
