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.

Economical efficiency of selected crops growing in conventional and organic farming system - case study
PICKA, Adam
This bachelor's thesis deals with an overview of the economic efficiency of growing field crops (winter wheat and winter barley) in an agricultural enterprise in the district of Jindřichův Hradec. Both crops are solved from the economic point of view of cultivation in both organic and conventional farming systems. The costs of growing plants, yield and average price production are calculated from the management procedures of the company, and then the economic efficiency of growing the crops is evaluated. The result is then compared with that of an organic farm that grows crops in comparable habitat conditions as a conventional farm. The difference between inputs and outputs in individual types of management is calculated and subsequently the results of the given management systems are evaluated.

ILCA for selected cereal species
PANUŠKOVÁ, Šárka
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.

Příčiny nízkých výnosů obilovin v ekologickém systému pěstování
KOTAŠKA, Vladimír
The aim of this diploma thesis was to find out the causes of low returns on chosen cereals (oat, wheat, rye, and spelled) in ecological agriculture based on evaluating information on growing procedures obtained via the method of questionnaires. Gradually, 21 ecologically farming companies controlled by the Abcert AB a Biokont CZ, s.r.o. organizations were chosen. Based on the analysis of growing procedures, the most frequent mistakes made by farmers were identified. Companies with lower returns apply mainly an inappropriate structure of crops grown, a high representation of cereals, and they do not respect crop rotation principles. Especially in favourble conditions, some farms are run without livestock production. Leguminosae representation is low in most companies, intercrops are used very seldom. In case of straw plow, the C:N ratio is not maintained using manure. Mineral manure is not used at all, liming very seldom. Vegetation is usually not fertilized during vegetation period. Cereal weed regulation is carried out, but not sufficiently. Using farm seed is quite frequent, which increases the growth of weed. Comparing returns on cereal among better and worse companies, it is obvious that respecting given principles may increase return on seed in 1.0 to 1.9 t/ha.

Quality of poultry meat in relation to the production method
KADLECOVÁ, Lucie
The topic of this thesis is the quality of poultry meat in relation to the production method. In the literature review, poultry meat is described, then its consumption in the Czech Republic and its chemical composition. Selected methods of sensory analysis are also described. Types of tested meats are characterized in the practical part. This thesis is also focused on the experimental evaluation of the chemical composition of chicken breast muscle from the Loužná farm using the NIR method and comparing the composition changes depending on the age of the chickens. It is followed by selected sensory methods aimed at recognizing differences in chicken meat from three different productions. In addition, there was published a questionnaire to determine citizen's preferences for products (chicken meat) from different production methods.

A comparison of the legal regulation of conventional and organic farming
Marko, Jan ; Damohorský, Milan (advisor) ; Humlíčková, Petra (referee)
Resume Agriculture has intensified greatly in the last century and heavy machinery and chemical substances are being used, which causes negative impact on environment. On the other hand, organic farming tries to use natural resources with utmost care and rejects synthetic substances. The main goal of the thesis is to find and describe the most important differences of the legal regulation of conventional and organic farming. International regulation, regulation of European Union and Czech regulation are the main focus of the thesis. The first chapter tries to characterize conventional agriculture and describe its functions, briefly goes through its development and current status. Chapter deals with causes, subject and purpose of legal regulation and analyzes sources of law in the international law, European law with main focus on Common Agricultural Policy and Czech law. The second chapter is concieved similarly as the first one, but from the view of organic farming. It characterizes organic farming, describes its development and legal regulation on the international, European and Czech level. The third chapter takes a closer look on chosen institutes and sections of Czech legislation and tries to show the most important differences of conventional and organic farming. Chapter deals with agribusiness and...

Quality of poultry meat in related with production method
KADLECOVÁ, Lucie
The bachelor thesis is focused on the analysis of the basic components of breast cutting from free-range and conventional breeding of chicken. The samples of free-range meat came from Loužná farm; the conventional samples came from poultry farm in Klatovy. The main aim of the thesis was to determine the water, fat, protein and collagen content in meat using NIR methods. The literature review explains differences between the ways of breeding, various effects on the quality of meat and meat defects. In next chapters, the results of the measurement compared to findings from the literature and food standards are presented. The conclusion contains a summary of all facts.
