Vliv technologie pěstování cukrové řepy na množství a kvalitu půdní organické hmoty
NOVÁKOVÁ, Aneta
The diploma thesis is focused on monitoring the content of soil organic matter and its quality in two variants of samples. The main goal of this thesis is to analyze and compare the values of soil samples taken in the sugar beet using two different variants of agrotechnical interventions - mechanical weed control with loosening and a variant using pesticides without loosening. Sampling took place near the village of Úhřetická Lhota in the Pardubice Region. The samples were processed in the laboratory and after their analysis the monitored parameters of quantity and quality of soil organic matter were determined: CPPOH - carbon of primary soil organic matter, CSOF - carbon of stable organic fractions, Corg - total organic carbon, constant k - quality indicator of primary soil organic matter

Porovnání orebného a bezorebného zpracování půdy na základě ekonomických ukazatelů
ALEXA, Jaroslav
This work focuses on the comparison of plowing and without plowing tillage technology based on economic indicators. In particular, the times of individual work operations, costs of staff, and fuel were compared. In order to collect data, a field experiment was performed on two adjacent plots using different tillage methods. The values obtained from the individual plots were compared with each other.

The fundamentals considerate of the soil cultivation and land improvement at the ecological technique farming (with specification at the marginal area Šumava)
VIKTORA, Lukáš
The principal aim at this bachelor work is the strike a balance farm{\crq}s conversion from ecological to conventional farming from the aspect land improvement and economize. The first part of the bachelor work is dedicated to the problems of soil cultivation in the two types of farming. There are underline the main piece of knowledge in terms of rotation of crops, the forms of soil cultivation, the fertilization and the others subjects, which equate to conveniences and disavantages bio-farm opozit the classic. In the practical part there is take the progress of farm SHR Victora, which is in the beginning ecological farming applied mainly because of reversion. After the farm was compelled changed your status and use the classical way because of competitive advantage. At the soil cultivation and in the rotation of crops the farm kept the ideas of ecological farming. At the and of the work there is the resume of the results and thera are suggestion the acqusition for conversion to integrated farming.

Design of a stubble disc cultivators for aggregation with a tractor 50k
Pech, Vladimír ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This thesis deals with the design of a stubble cultivator for a tractor. The aim of this thesis is to design a stubble cultivator that fulfill the conditions of the assignment. In this thesis is a search of similar machines available on the market. Followed by describes the methods of tillage which the proposed stubble disc cultivator is used. The next part of the thesis describes possibilities of stubble cultivator their advantages and disadvantages. The design part deals with the construction which is based on drawing documentation. In the next part of the thesis is a calculation which is focused on determination of the required tractor power that is needed for operation with the designed stubble disc cultivator.

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...

Stanovení vybraných parametrů rozdílných způsobů zakládání porostu cukrové řepy
CHADRABA, Václav
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.

Využití hloubkového kypřiče při pěstování obilovin a řepky olejné
MICHEK, Aleš
The diploma thesis deals with the comparison of two technologies for soil cultivation in winter rape and winter wheat growing in 2017 and 2018. The first technology is a conventional technology, or classic using plowing and the second one is a minimization technology, where plowing is replaced by loosening. The work is focused on the comparison of fuel consumption, investment and operating costs, exploitative indicators and machine work quality. Furthermore, the thesis is focused on the description of particular machines and the company of primary agricultural production, where the machine is used.

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 konvenčního a minimalizačního zpracování půdy
POLAN, Tomáš
This bachelor thesis deals with soil tillage systems. It contains of using individual technologies with regard to fuel consumption, time needed for operations and condition of growing crops. Machines used for the tillage are also described in this thesis. The experiment was realized in a single groundfield which was divided to avoid distortion of results by different soil quality.

Měření spotřeby pohonných hmot různých konstrukcí pluhů
ŠVEC, Tomáš
The aim of this thesis is to measure the plowing set´s consumption of fuel using unilateral and reversible plow under equal conditions of an agricultural enterprise in the Czech Republic, and to evaluate the obtained results. Another aim of the thesis is to respond to scientific hypotheses as to which of the observed technologies has an impact on cost savings and whether this technology has an impact on the quality of the crop. The content of the thesis is a description of soil and its characteristics, it further deals with soil processing, tillage especially and its parameters, and tools needed for these operations. It then describes plow construction especially. Last but not least, the thesis contains factors which may influence work economy. The measuring has clarified the consumption of unilateral and reversible plows´ set under equal conditions. Based on this consumption it was found out which technology is more economical, optionally giving the growth of percentage.
