Porovnání diskového a radličkového podmítače
NOVOTNÝ, Filip
The diploma thesis deals with an issue of stubble plough under and a comparison of dise and skive stubble ploughs. The introductory theoretical part sums up the basic information about a soil and its treatment, information about agricultural machinery and concrete sorting stubble ploughs according to their working organs. A short history of Lemken company follows. The second part of the thesis compares the disc and the skive stubble ploughs in conditions of the agricultural company Zas Dražice Plc. Following gauges were examined during the field tests: cloddishness in cultivated part of the soil, defray postharvest rests, gas consumption or investment and operating costs.

Comparison turntable and stubble plough in light of qualities effected stubble ploughed under and gas consumption.
RŮŽIČKA, Jiří
This thesis concentrates in problematics of stubble ploughed under and comparission disk and skive stubble plough. First part contains the summary of theoretical knowledge of soil and its elaboration, as well as the knowledge of farm machinery and specific division of stubble ploughs by its working organs. Follows by the summary of the most used and sold stubble ploughs in Czech Republic within its detailed description. Second part constitutes confrontation of skive stubble plough and turntable stubble plough in conditions of company Agro Malinová. In the field experiment have been discovered these measurements: defray postharvest rests, worked profile, cloddishness, penetrometer resistency, gas consumption and soil humidity.

NOVOTNÝ, Filip
This bachelor thesis deals with plate stubble cultivators, their use in soil cultivation and planting of stands with a description of their individual types and agrotechnical requirements for them. The thesis also deals with minimization technologies for soil tillage and description of advantages and disadvantages of each method. The first part of the bachelor thesis summarizes the history of soil cultivation from the very beginning of the development of agriculture to modern technology. The importance and design of the stubble is also described here. The practical part focuses on the methodology and the results of the measurements in connection with the quality evaluation of selected Lemken Rubin 9 plate stubble cultivator, Disc Profi X 5000, Väderstad Carrier CR 350 and Pottinger Terradisc 6001 T in the field of unclopped plant residues, clods remains at set speeds, productivity, fuel consumption, and investment and operating costs. The work is supplemented by the basic characteristics of the machine owner and the characteristics of the agriculture company, where the measurements were made.

HEŘMÁNEK, Aleš
The Bachelor thesis deals with strip tillage technology. It describes possibilities of its use and technological options, which are available at present. Furthermore, not only advatages of the strip tillage technology towards the environment and soil are described in this theses, but also certain limitations and pitfalls, which may appear while using such technology. The first part of the thesis is focused on history of soil proccessing starting with the very first agricultural tools. Use of the first mechanization operations with soil while using the first plows, are captured in this thesis, followed by a description and distribution of minimization technologies, including strip tillage technology. The information are complemented by a description of agriculture machinery. The practical part deals with metodology and results of measuring related to performance of a selected seeder, the Mzuri PRO-TIL 4T. One of the evaluating criteria was setting up the depth of soil processing, the number of lumps as well as the amount of plant remains in the particular strips of the area, the number of grown plants, placing seeds into the desired depth and efficiency of the specific set. The thesis is complemented by specifications of the agriculture company HZT Technik-servis, a.s., as well as by a simple analysis of investment and operating costs.
