Crop flow improvements at the Power Flow header
Štelcl, Michael ; Červinka, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The master's thesis is focused on a design of optimal working speed of auger and belt transporter which are parts of Power Flow header for standard type of combine harvester. In the master's thesis author suggest a new simplified theory of crop flow inside the Power Flow header. The thesis contain the factors which can affect the crop flow and comparison between the Power Flow and competitor's header. The thesis also contain geometrical characteristics of crop for four types of cereal.

Bucket elevator
Sochor, Tomáš ; Malášek, Jiří (referee) ; Jonák, Martin (advisor)
The aim of this thesis is a design of a vertical bucket elevator which is to be used to transport cereal. The transport height is nineteen meters and transport capacity one hundred tons per hour. This thesis consists of a description of the vertical bucket elevator and its main parts which are mentioned in the introductory list. The thesis deals with functional and capacitive calculations, determining a drive and a tensioning device. Another calculation has the function of control a drive shaft, calculation of spring, lifespan of bearings and a calculation of the tensioning device. In addition, there is a design study according to the assignment.

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.

Quality of cereal seed in the Czech Republic
BENKOVÁ, Ludmila
High quality multiplication material is created directly on a field. It's always about relation between seed and environment which is influenced by farmer. Within the Czech Republic the samples of certified cereal seeds were taken from the representative farmers, farm cooperatives and agricultural companies. After that they were subsequently analysed. The whole mentioned seed samples of the year 2013 comply with the legislative requirements. The term "seed quality" is often perceived as a subjective matter. Via questionnaire miniresearch it was found out how growers perceive offer and certified seed quality. At the same time the analyse of the actual certified organic seed need in the Czech Republic was carried out according to the given data of Central Institute for Supervising and Testing in Agriculture. The results doesn't correspond to the real cereal organic seed offer. The present situation in certified seed quality and organic seed offer represents an appeal for improvement and the future necessary amendment to the low.

Rol of sacharides in nutrition
JURÁK, Ondřej
In the theoretical part of the bachelor thesis basic characteristics of the sacharides were handled by form of literary searches. Further, the properties of basic cereals and cereal products were described, including the chapter about digestion and absorption of carbohydrates in the human organism. Last part describes cereal products, especialy breakfast cereals, their prevalence and importance in the diet of school pupils and students. The aim of the research part of the bachelor thesis was to realize and analyse a questionnaire survey in the segments - pupils of higher grades of elementary schools and students of universities, focusing on the validation of the knowledge about carbohydrates, cereals and its consumption. The first partial aim was to determine the interest of pupils of higher grades of elementary schools and students of universities in different kinds of cereals products. The second partial aim was the comparison of the dieatary habits of pupils and students. On the basis of targeted objectives, three working hypotheses were formulated and verified. The validity of the first hypothesis - pupils of the second level of elementary schools have less knowledge about carbohydrates and cereals products than the students of universities, was confirmed by the analysis of responses from the questionnaires. The validity of the second hypothesis - students of universities prefer breakfast cereals more than pupils of higher grades of elementary schools, has also been confirmed. During the analyses of answers related to the third hypothesis - pupils of higher grades of elementary schools have better forenoon eating habits, than students of universities, it was found that students of universities have better eating habits than pupils of elementary schools, however pupils have better eating habits during snacks.

The Use of Mechanically Modified Cereals in Semi ? Intensive Culture of Market Carp
VODÁREK, Michal
120 day feeding experiment was executed on the Trebon fishponds in the area of feeding the market carp. The aim was to determine what way of cereals processing will have favorable effects in terms of production efficiency in the mechanical processed cereal by grinding and mashing in comparison with cereal without processing. The theoretical part focuses on the characteristics of natural food, technology feeding, feed distribution and appropriate processing to achieve high growth results in common carp (Cyprinus carpio). The practical part includes the methodology and results of the production parameters of carp fed by triticale without processing, by grinding and mashing. The highest feed efficiency was observed in carps under supplementary by triticale mashed feeding with FCR 0.83; 1.21 kg of FCE and FCR / SGR; 1.05; the highest growth rate was achieved in carp under supplementary by grinded triticale (1,2 mm) feeding with SGR: 0.86 %.d-1.; worse results were observed in carp feeding by triticale without processing: FCR: 1.27; FCE: 0.79 kg; FCR / SGR: 1.61; SGR: 0.79 %.d-1.

Influence of feedstuff and breeding technology on changes of common carp´s (Cyprinus carpio L.) and of european catfish´s (Silurus glanis L.) mass quality
ZAJÍC, Tomáš
The work is focused on the nutrition and farming technology influences on the changes of the quality of common carp (Cyprinus carpio L.) and european catfish (Silurus glanis L.) meat. For the first experiment were used 6 groups of fish (common carp). Five of those were fed on cereals (maize, wheat, triticale, rye and barley), the sixth group was left on natural food by way of the control group. For the second experiment were used two groups of fish (european catfish). The first group was bred by the classical technology in fresh water ponds using natural food (dietary fish) by way of the control group. The second group was bred intensively in warm water in controlled conditions using feed compouned. In both of groups were defined following characteristics: weight yield, sensoric analysis, content of nitrogen compounds, fat content and spectrum of fatty acids in fat. It was ascertained that the rearing technology affects the results in all monitored characteristics. The biggest attention was payed to the results of fatty acids spectrum. While in the test using common carp was proved a higher proportion of PUFA (inclusive EPA and DHA) in the control group, in the test using catfish was this proportion higher in intensively reared group.
