Disc trencher for mechanical soil preparation before to afforestation
Chupík, Vojtěch ; Malášek, Jiří (referee) ; Mergl, Václav (advisor)
This bachelor thesis deals with the complex design of a disc trencher carried by a tractor, power class up to 110 kW. The initial research presented methods of mechanical soil preparation prior to afforestation, examples of disc cutters available on the market and the machine design concept. In the next section, a complete CAD model of the entire disc trencher was presented, followed by a more detailed design of the individual components. The work also includes calculations to determine the power required to drive the machine and the choice of drive type for the disc wheels themselves. Strength calculations and subsequent checks were performed on the selected components. The result of this work is a complete assembly of the disc trencher and its drawing documentation.

Porovnání exploatačních parametrů kotoučových a radličkových podmítačů ve vybraném zemědělském podniku
PROCHÁZKA, Miroslav
The aim of this diploma thesis is to approach the possibilities of processing agricultural land with a suitable type of cultivator. The professional part of the work captures different types of tillage and introduces the types of cultivators. The practical part of the work is devoted to measuring the area performance and fuel consumption in soil preparation with a coulter and disc cultivator in the specific conditions of an agricultural enterprise in the Czech Republic. Evaluates the measurement results and presents conclusions for practice.

Hodnocení způsobů výsadby a povýsadbové péče na růst sazenic révy vinné
Holánek, Jiří
The aim of this thesis was to conduct operational monitoring of selected machines in the process of planting a new vineyard. The thesis focused on choosing a suitable site and a subsequent pre-planting preparation. Individual methods of site preparation, technological methods of planting a vineyard and different types of supporting systems were all described in the theoretical part. The objective of the practical part was to monitor the machinery operating and fuel costs. Measurements of time consumption of individual working operations and cost calculation were also conducted, and a required number of workers was recommended. Last but not least, models of different technological methods for planting a vineyard were developed and cost differences of individual methods were observed. Finally, measurements and evaluation of seedling establishment and growth during the growing season of 2018 were conducted and statistical outputs were derived from the data. The thesis yielded a large amount of data suitable for further practical application.

The technology of cultivation of spring barley (Hordeum vulgare L.) and its use
KRUML, Martin
The aim of my thesis was to introduce you to using research to the cultivation of spring barley (Hordeum vulgare L.). Cultivation of barley, I mean everything from the biological characteristics through soil preparation to planting and harvesting. For this search, I used books by Czech authors who write on this subject, as I used articles of foreign authors writing about issues influence of fertilization on spring barley, and I took advantage of practical experience with the cultivation of spring barley agronomists working in the company ZKS AGRO Zahořany. I tried to encompass the whole issue of growing spring barley and all carefully recorded.

Use of seeding machinery for soil preparation in the cultivation of cereals
JÍRA, Václav
The aim of the thesis is to extend knowledge in terms of the application of modern seeding machinery for soil preparation for sowing in the cultivation of cereals. In the literary section of the report a brief overview of the use of seed drills for minimum tillage. Load small-plot experiment on the selected station and simultaneously perform evaluation activities seeders work to prepare the ground in terms of quality seed, seed depth, coming in plants (growth phase), or the occurrence of weeds. The thesis will brief overview of the analysis of operating costs. The results evaluate and propose recommendations for possible use in agricultural practice.
