Porovnání rozdílné technologie zpracování půdy na výnos jarního ječmene.
BENÁČEK, Vojtěch
In my diploma thesis, I will deal with the comparison of two different technologies. This work will be carried out on a stand of spring barley and will follow on from the bachelor's thesis, which was created in the same company. The first technology will be classic ploughing, while the second technology will be tillage using a chisel plow that works up to a depth of 50 cm.

Analysis of energy and performance parameters of tractor sets for tillage
Masnica, Daniel ; Porteš, Petr (referee) ; Bauer, František (advisor)
This diploma thesis analyzes the influences of individual components and settings on the performance and energy parameters of tractor sets. The theoretical part of the thesis focuses on tractor construction and describes some electronic systems used in modern tractors. It also describes the methodology of field measurements, measuring techniques, and machinery used for the measurements. The practical part of the thesis deals with field measurements of a tractor set with a combined cultivator, a plow, and traction tests of the tractor. From the measured data, various performance and energy parameters are calculated. The results are analyzed, and a discussion is provided.

Measurement and evaluation of exploitation and qualitative indicators of ploughing on the specific land
EIBL, Jiří
This diploma thesis focuses on the history of plough production, on the description and using the plough for basic typical soil tillage. Mechanical soil cultivation, that makes the soil loosed, divides, turns and mixes ploughed materials with soil. This process is called ploughing. Stubble-tillage and ploughing is the aim of this thesis, it was done on the determined land with the semi-mounted plough (five- and two- blade insert), and with the full-mounted plough (front part UPS, five- and two- blade insert). There were compared current exploitation and qualitative indicators during the working with the plough in comparable conditions.

Využití hloubkového kypřiče při pěstování obilovin a řepky olejné v podniku Zemědělské služby Dynín, a.s.
KUBEŠ, Jan
This diploma thesis deals with deep cultivators which are used in companies of agricultural production. Theoretical part is focused on the history of soil proccessing, soil treatement and loosening machines which are being used today. That includes disc cultivators, tine cultivators, chisel cultivators, rod cultivators and machines with driven work gears. Practical part of theses includes comparison of chisel cultivator and plough doing tillage. The quality of keeping the depth invariable is being evaluated, as well as time-consuming nature, consumption of fuel and drain on resources.

Porovnání orebné a bezorebné technologie zpracování půdy z hlediska jejího zhutnění
MACH, Václav
The bachelor thesis focuses on technologies of soil cultivation which are nowadays most frequently used in our country and what is their influence in soil compaction. It describes reasons of the origins of soil compaction, impacts of the compaction and the effect of compaction on soil as a unit. It also focuses on procedure? against unwanted compaction or its following elimination. Subsequently, the thesis describes basic work operations which are plowing and aeration. There are details of the principle how the plough works, basic types of ploughs and the way how we can divide plowing. There are also methods of plowing which are applied in different conditions on land. Last but not least, the thesis points out advantages and disadvantages of this most common soil cultivation. It deals with technologies of aeration as well as it deals with machines which are able to cultivate soil or with technologies of soil cultivation and their advantages and disadvantages in work without a plough. The field experiment which has been done for drawing up of this bachelor thesis focuses on comparison of ploughing and non-ploughing technologies of soil cultivation in a way of its compaction. There is evaluation of the penetrometric resistance, of the achieved depth in measurement and the soil moisture. These values have been measured on a field which was divided according to the technology of soil cultivation. The first part was done conventionally with the plough and in the second part the plough was replaced with the aeration. The results of the measurement were then compared with the whole soil profile of the measurement, then in the depth of 20 cm and finally with rest the horizon of measurement. Values and comparisons of the individual measurements are for better illustration noted in tables and marked on graph.

Porovnání výkoností a spotřeb pohonných hmot v přípravě půdy
KUKLA, Martin
In Bachelor thesis threre is analysis the princip of activity of individual types of machines, which are designed to tillage and their effective use. In the thesis there is a question, which preparation of soil is the most suitable in connection with time, which is needed for manage work, demands for fuel and the final yield of harvested crops. For measurement there were created two land on one field, so the soil properties was the same. It means that there is a minimmum of distortion of measurement results
