Výnos semen řepky olejné v odlišných agroekologických podmínkách
Krejčířová, Markéta
The aim of this work is to analyse the relationship between the yield of rapeseed and the factors which affect its formative. In the first part of the work is research of literature sources about rapeseed as a crop with a more detailed focus on biotic and abiotic factors influencing its yield. In the practical part are firstly evaluated test stations, from which we get the data on rapeseed yields in the Czech Republic. Their inclusion in the warm or cold region is compared with the evolution of the climate in recent years and a new classification is proposed. Then data on rapeseed yields at these stations during the last twelve years is analysed.

Vliv ošetření osiva superabsorbčním polymerem na vzcházení, růst a výnos plodiny
Lokaj, Lukáš
The thesis deals with the use of a superabsorbent polymer, specifically seed coated with this polymer and the evaluation of emergence, growth and yield of the crop. One part of the experiment was carried out in the laboratory, namely plant germination, while the second part was carried out under field conditions on the land of the School Farm at the site of Žabčice in the years 2020–2022. The effects of SAP seed treatment on germina-tion, emergence and crop yield were monitored. Four experimental treatments were evalu-ated for wheat, barley, maize and rape, namely seed untreated, seed treated with SAP, seed picled and seed picled and treated with SAP. SAP treated seed germinated faster for all crops. For wheat variety Luana and maize variety Celong, SAP increased yield by al-most 0.5 t/ha, and for rape by 0.7 t/ha. Barley and maize variety Alombo were negatively affected by SAP.

Charakter komoditní vertikály řepky olejné
Dohnal, Štěpán
This bachelor thesis deals with the description of rapeseed commodity chain in the conditions of the Czech Republic. The commodity chain is defined based on specialised literature and available statistical data. The thesis deals with the cultivation development of this crop with a focus on factors that determine this development. Thesis defines the usage in the the processing industry and shows the causes of high utilization of this crop over past years. Moreover, it defines the price development of this commodity. Rapeseed is an important export commodity and that is why the development of foreign trade with rapeseed and its products is defined in the final part. Based on the analyses it was found out that the Czech Republic is one of the biggest producers of rapeseed in the European Union. One of the main reasons of its expansion on the Czech fields is its usage for producing the biofuels.

The effect of rape seed treatment with oomycete Pythium oligandrum on plant metabolism
Vaverová, Kateřina ; Ryšlavá, Helena (advisor) ; Müller, Karel (referee)
Lot of attention is paid to biological control agents of plant pathogens as it will reduce the amount of pesticides used in agriculture. Pythium oligandrum oomycete is already used commercially in the form of watering and spraying. In this work the properties of other isolates were characterized, and the metabolic changes were studied in plants of oilseed rape (Brassica napus subsp. Oleifera), whose seeds were treated with preparates based on Pythium oligandrum. In the first part of the thesis the properties of compounds secreted by isolates of Pythium oligandrum were tested. The amount of phenolic substances and the activity of endoglycosidase endo-β-1,3-glucanase, cellulase, chitinase as well as proteases were measured to assess the ability of oomycete Pythium oligandrum mycoparasitically protect the plant. Substances, especially oligandrin, which during interaction with the plant are responsible for "priming", have been observed, enabling the plant to respond rapidly to pathogen infection through systemic plant resistance. Differences between individual isolates also manifested themselves in electrophoretic separation in the protein representation. In the second part of the work, the effect of rapeseed seed treatment with isolates of Pythium oligandrum on plant metabolism was monitored. While...

Vyhodnocení aspektů formující komoditní vertikálu řepky
Martínek, Jan
This thesis deals with the characterization and description of the commodity chain of rape oilseeds. It defines the development of production and production areas in the European Union and worldwide. Part of the work is devoted to the development of the commodity chain of oilseed rape in conditions of Czech republic. It describes and compares the review of the utilization of rape oilseed in our country. It analyzes foreign trade with this commodity and evaluates the long term developments in the process of EU enlargement. The work characterizes the price trends of oilseed rape and its potential impact on the price of petroleum. Using the data obtained, there are evaluated possibilities of rape oilseed in the future. The obtained results show that the Czech Republic is among the most intense growers and producers of rapeseed in the EU 28 and in the world.

Vývoj produkce a struktury podniků v komoditní vertikále řepky v ČR
Vacková-Veselá, Lenka
This diploma thesis defines the evolution and changes of canola commodity chain in Czech Republic focusing on primary production and processing stage. Through literature review, based on the theoretical and methodological foundations of agribusiness, canola commodity chain, its determinants, and biological charac-teristics of the commodity are defined. Through analysis of secondary data is captured supply formation and evolution of oilseed rape production in the Czech Republic. Also there are identified changes in the structure of agricultural holdings in given commodity vertical.

Formování komoditní vertikály řepky na společném trhu EU
Vargová, Petra
The Diploma thesis is focused on the formation of commodity chain rapeseed on the common EU market. It reports the development of the supply side of rapeseed, rapeseed oil and biofuels on the world and european market. It identifies the main world and european production centers within those commodities. The development of prices in selected stages of commodity chain is analyzed by using the agricultural producer prices and stock prices. The analyses are based on the evaluation of statistical data. The results confirmed the growing significance of rapeseed and growing presence of biofuels.

Důsledky přijetí směrnice 2009/28/ES pro pěstování řepky olejné v ČR
Náplava, Radek
This paper examines the implications of the adoption of Directive 2009/28/EC on the selected indicators. The theoretical part aims to describe oilseed rape, biofuels and Directive 2009/28/EC. In the practical part, there are actual consequences of the adoption of Directive 2009/28/EC on selected indicators oilseed rape, FAME and size of sowing areas of selected food commodities. In addition, is studied the influence on food prices, food balance, the price of food commodities and import of food commodities. Based on the collected data, I came to the conclusion that the adoption of the Directive, except larger sown area of rape probably had no demon-strable effects on examined indicators.
