Fertilization of maize sillage
VÁJA, Petr
This thesis is focused on an experiment dealing with fertilization of silage corn. The experiment was realized in 2021 in the agricultural enterprise Zemko Kožlí a.s. The field experiment was founded with a hybrid ES Joker and was fertilized with various combinations of fertilizers. In total, eight fertilization variants were created for the experiment in two repetitions. Fertilizers DAM 390, Urea and Amofos were used for fertilization. During the vegetation, differences between fertilization variants were monitored, namely in the number of plants, increase of above-ground biomass, weight of individual plants, weight and number of individual buds, and finally in the total yield from each variant. An additional criterion-em was the evaluation of the percentage of dry matter and the economic evaluation of each variant. The largest yield was recorded for the variant that was fertilized only with nitrogen in the fertilizer Urea. The lowest yield, on the other hand, was for the fertilized phosphorus variants in the fertilizer Amofos in combination with nitrogen in the fertilizer DAM 390. With the increasing dose of industrial fertilizers, the yield of biomass decreased. Experiments of corn fertilized with phosphorus reached higher dry matter.

Porovnání kvalitativních ukazatelů u sklízecích mlátiček s různou konstrukcí mlátících ústrojí
MRAZÍK, Václav
This thesis aims to compare combine harvesters and different thrashing system designs. The different types of harvesters, tangential, axial and hybrid thrashing systems for which measurements were obtained during conducted field work are described in detail. Obtained results are then presented together with discussion on conditions of each measuring activity. Individual stations are then evaluated and comparison of various qualitative attributes affecting the performance, quality and fuel consumption is presented. Evaluation of individual thrashing systems is presented in the conclusion of this thesis together with answers to questions regarding the methodology of conducted measuring activities. Finally, findings from this thesis are applied in practice.

Porovnání senážních linek s řezačkami Claas a John Deere
VÁJA, Petr
This work will try to compare lines for forage harvesting for silage, in two farms with a focus on production focus and production method of harvesting. The main value will be calculated in performance, fuel consumption and financial costs of individual work operations. All costs will be converted to 1 tonne of mass. Samples and proven subsequent analysis of the components will be taken from the final product.

Porovnání kvality řezanky u samojízdných sklízecích řezaček
HEŘMÁNEK, Aleš
This final thesis is dealing with feed production technologies interms of different species of plants for the purpose of livestock production or energetics. The thesis analyzes one particular technology because of wide range of options on the market nowadays. The resource review chapter provides comprehensive information about history of forage harvesters and their use in crop production up to now. A significant part of that chapter describes an overview of latest technology. The thesis focuses on self-propelled machines and is complemented by a description of individual technical solutions. The metodology part contains measurement procedure and comparison criteria of particular John Deere 8300 and New Holland FR 500 machines. All the measured values had been gathered between 2019 and 2020. These values have provided the main source for acquiring further subject. The points of comparison were feed quality, grain crushing, efficiency and fuel consumption. The last criteria in that comparison are operational costs of particular forage harvesters.

Radio reportage from traditional harvests in the Vysočina region
Máčala, Marek ; Lovaš, Karol (advisor) ; Gulda, Jana (referee)
The essence of this bachelor's thesis is to present the genre of radio reportage and its practical processing during the grain harvest also called žně. In the first part of the thesis, the author gives a theoretical introduction to the reportage genre and at the same time discusses its development on the domestic scene up to the present day. The thesis also describes the topic of the grain harvest, about which the author made a fifteen-minute long audio report. The second half defines the process of preparation for the shoot, the course of the shoot and the subsequent post-production. During the latter, the soundtracks were sorted and cleaned so that they could be worked with in the final editing.

Cereal in the medieval culture of the Czech lands
Freiová, Kristýna ; Czumalo, Vladimír (advisor) ; Hubáček, Ondřej (referee)
Agriculture makes its first appearance in human history about 12 000 - 5 000 years ago. Around that time, people took to a sedentary way of life so they could primarily till the land and grow the grains which they had come to know in their wild varieties. This new way of life gradually changed the social and cultural order. A return to primeval living was not impossible, though. Before the Slavs arrived on the territory of what is today Moravia and Bohemia, various Indo-European tribes had already pursued agriculture in our part of the world, chief among them the Celts and the Germans. The Slavs, which came from the eastern part of Europe, probably in the second half of the 6th century, built upon the farming of these erstwhile peoples. After the rise and fall of proto-states, for which evidence has survived only in the case of Great Moravia, an early Bohemian state took hold. In the local culture, grain played an indispensable role. Farming was the main livelihood of the entire populace. Crops of choice at the time were millet, einkorn, and emmer wheat, which gradually gave way to common wheat and barley. The land was tilled with wooden hoes which merely cut furrows in the soil. The grain, which was harvested using sickles, was stored in pits in the ground. To improve digestibility of the grain...

Porovnání sklízecích mlátiček různých výrobců při sklizni obilovin a řepky
ADAMEC, Petr
The diploma thesis on comparison of combine harvesters in terms of work quality is based on professional literary research, which describes the parts of combine harvesters from adapters to threshing devices. The methodology of this thesis describes the procedure for obtaining results and values for comparison between John Deere 9640 WTS, New Holland TC5060, Claas Lexion 450 and Sampo Comia C8 combine harvesters during work. The results and the conclusion of the work compare the calculated, measured and determined results achieved precisely according to the methodology of 2017. The combine harvesters are compared in the areas of work quality, namely in the lossability, the theoretical throughput, the quality of spreading and crushing of straw and finally in efficiency and fuel consumption. The work also includes the costs associated with opearting combine harvesters.

Agrotechnická opatření při pěstování a sklizni Stévie sladké (Stevia Rebaudiana Bertoni) v polních podmínkách
HAUSEROVÁ, Tereza
Stevia or Stevia rebaudina Bertoni is a plant with very intresting but up to this date not very utilised potential. It a subtropical plant with a sweeting power us much as 300 times higher than in case of sucrose. It is often used as a compensation for sugar- sweetener, suitable for diabetics and people who suffer from overweight. There is processed the characteristics of the plant, botanical description, conditions of cultivation and chemical composition. The practical part elaborates on growing stevia, her germination, reproduction, growing in field conditions and hibernation. The purpose of the thesis was to expand the knowledge regarding cultivation, reproduction methods and wintering options of the stevia plants. A field and a greenhouse experiments were staged with a focus on temperature indicators during the growing season and their impact on the total number of wintered plants. The dry matter yield of the plants was rated per an area unit and statistical processing with experiment results.
