The aim of this work is to identifily the current coverage of fields by plants on a specific farm. The chosen farm was Uniagris a.s. Observation took place in growth areas of winter rate, winter wheat and corn wheat. Evalution was carried out counting methods. The results of the weed infestation evaluation were processed with the DCA analysis. The canonical corespondence analysis showed that, in the poppy were found : Cirsium arvense, Fallopia convolvulus, Papaver rhoeas, Tripleospermum inodorum, Chenopodium album, Polygonum aviculare, Brassica napus. In the winter rapeseed were: Capsella bursa-pastoris, Descurainia sophia, Euphorbia helioscopia, Fumaria officinalis, Galium aparine, Lamium purpureum, Myosotis arvensis, Papaver rhoeas, Thlaspi arvense, Veronica hederifolia, Viola arvensis. In spring barley were: Fallopia convolvulus, Galium aparine, Papaver rhoeas, Thlaspi arvense, Chenopodium album, Polygonum aviculare. In corn wheat were: Echinochloa crus-gali, Equisetum arvense, Fallopia convolvulus, Brassica napus, Viola arvensis. In winter wheat were: Agropyron repens, Brassica napus, Cirsium arvense, Echinochloa crus-gali, Equisetum arvense, Fallopia convolvulus, Galium aparine, Lamium puprureum, Tripleospermum inodorum,Veronica hederifolia, Viola arvensis. In sugar beet were: Cirsium arvense, Fallopia convolvulus, Triticum aestivum, Veronica hederifolia, Chenopodium album, Polygonum aviculare.

This thesis deals with a growing trend of the sugar industry in the Czech Republic. The first part of the work is focused on analysing of the agriculture aspects of the cane sugar cultivation. The following chapters are given to the world sugar production. The most important section the thesis is focused on development of the sugar industry and cultivation of sugarbeet in the Czech Republic, i.e development of the acreage of sugarbeet, rate of sugarbeet acreage on czech districts. Final part is given to the analysing of the sugar industry restrukturalization and influence of the European Union on the common trade of the given industry.

The work is focused on operational comparison of two technologies of sugar beet growth. The comparison took place on two adjacent plots with almost the same properties. On the first plot the stand was based on Stip-Tillage technology. On the second plot was used minimalization technology, specifically loosening and subsequent preparation before sowing using a compactor. Several parameters of the soil preparation were evaluated on the plots. Subsequently, the vegetation was monitored during the growing season. The thesis is also supplemented by yield parameters and simplified economic evaluation.

The Diploma Thesis is focused on the effect of the preparation Terra-Sorb which contains free amino acids, on the yield and the quality of choosen field crops. The main attention is pursued especially on the use of nitrogen and aminoacids in the plant nutrition. It's analyzed mainly in the literature review which is also focused on the intake of the nutrient and foliar nutriet of the field crops. The practical part is focused mainly on the verification of the effect of the stimulator Terra-Sorb. It's effect was verified during annual and perennial small plot trials on the location in Velká Bystřice. There were verified the different applications of the stimulator Terra-Sorb in the winter wheat, sugar beet and spring barley. There were evaluated yield and quality of each crops.

The thesis deals with the economic evaluation of sugar production chain. The first part of the work includes general charasteristic of sugar beet with detailed description of its attributes and importance, its quality, realization of sugar beet together with an economy of suger beet growing. Another part of the work is orientated on sugar beet manufacturers. It contains sugar industry development in the Czech Republic and technology of sugar beet process for sugar and bioethanol production. Also results of 2014 a 2015 campaign and future vision situation after 2017 is included. The third part of the thesis deals with sugar consumers and a foreign trade of sugar. The own part of the work focuses on sugar beet cost and rentability of sugar beet growing and sugar or bioethanol production. Also an impact of selected variables on sugar consumption is analyzed.

This thesis deals with the evaluation of the concept of fair trade, specifically its impact on economic, social and environmental spheres of the life of producers and their communities in developing countries. The theoretical part defines the concept of fair trade, presents the historical development of the concept, discusses its main actors, principles and products; finally, it incorporates the issue into the theory of international trade. The main part of the thesis presents selected case studies that examine the impact of the participation in the fair trade system on producers of coffee, cocoa, bananas and sugar cane, and reveal whether fundamental objectives of the movement have been fulfilled in these cases.

This thesis consists of an analysis of the works of two Cuban authors of the first half of the 19th Century, Francisco de Arango y Parreño and José Antonio Saco. This paper focuses on their works, mainly on those that discuss the topic of slavery. The first chapter introduces the evolution of slavery and its end throughout the Word and in Cuba, focusing on the development of the Cuban society in the 19th century, in which both of the authors lived and created. The second chapter analyses the works of Francisco de Arango y Parreño, his gradual development of ideas and views on the subject in connection with historical events that influenced his works. The third chapter is comprised of similar analysis of José Antonio Saco's works. The conclusion compares the works of both authors and highlights the points in which their views coincide or diverge. Key words: Francisco de Arango y Parreño, José Antonio Saco, slavery, slave trade, abolitionism, sugarcane, Cuba, 1st half of the 19th cent.

(in English): The aim of this thesis is to introduce the theme of the Canary emigration to Cuba in the second half of the nineteenth and early twentieth century. For better orientation, the author has chosen time interface between the years 1860-1914. The introduction outlines the sources and secondary literature, from which the author draws and also supposed goal of work. The second chapter is devoted to the Canarian emigration from Columbus's expeditions to the first half of the nineteenth century and its gradual development. The third chapter describes the specific reasons that led to the emigration from the Canary Islands, the attention is focused on the travel conditions of immigrants, employment contracts and promotion. The fourth chapter has been devoted specifically Canarian immigrants and their impact on Cuba, including labor stratification. The fifth chapter focuses on emigration to the turn of the century, there is a special attention is paid to the topic canary societies and associations.
