Technická úroveň traktorů používaných aktuálně v zemědělství
LIŠKA, Michal
The historical development of tractors is summarized in the theoretical part of the bachelor thesis. Furthermore, the technology of currently used tractors and a description of the individual systems that currently used tractors in agriculture have are described here. In the practical part, based on a questionnaire survey, the development of tractors in selected agricultural enterprises in the vicinity of Jindřichov Hradec and their current technical level are monitored. Information from individual agricultural enterprises is subsequently summarized in statistics showing the shift of tractor vehicle fleets in the selected area.

Metody hodnocení nevyrovnanosti pozemků v precizním zemědělství
Valík, Jan
Nowadays there are increasing demands on farmers and the quality and quantity of their production and its impact on the environment. Precision agriculture is a management method that emphasizes land heterogeneity in relation to input optimalization. Thus, the impact on the environment is reduced and material inputs are used effectively. To use the methods of precision agriculture, it is first necessary to have comprehensive information on the heterogeneity of land. Without them, it would not be possible to use precision approach. This work deals with mapping land heterogeneity for the purposes of precision agriculture. Direct and indirect methods are used for mapping. Direct methods include soil and plant sampling and their following processing. Today, indirect methods using sensor technology for estimating soil and vegetation properties are increasingly used. The practical part of this work is devoted to the evaluation of heterogeneity mapping methods used by the Agroprogres Kateřinky s. r. o. company in the Opava region.

Vliv parametrů pozemku na nasazení techniky
Šmíd, Zdeněk
Data management helps farmers to better organize their work and plan the movement of machinery in the field, depending on legal or geographical conditions. Guidance, data collection and software used for optimization, as well as its functions, possibilities and working environment are described in the theoretical part of the work. Furthermore, the methodology describes the methods of measurement and evaluation. The own work verifies the effect of optimization on the operation in the field. The verification was realized by collecting data of the movement in the field and their subsequent evaluation. At the end of the work is the evaluation of the measurement results and whether the optimization of the movement of machines on the land makes sense. By processing the results, it was found that the optimization of guidance lines around the land reduced the time required for turning by up to 21 % and thus the consumption of diesel by 6,5 %.

Porovnání secích strojů v konvenčním a precizním zemědělství
BAUMRUK, Jan
We will focus on comparing the same set, which is equipped with a GPS control system. In the first attempt, the set will be controlled by the navigation system when sowing winter wheat, in the second attempt the set will be controlled by the driver. For these experiments, all available parameters will be measured. The return, performance and economy of the whole set will be calculated from these parameters.

The yield and quality of spring barley in depending on nitrogen fertilization
MACHALOVÁ, Tereza
This diploma thesis deals with nitrogen fertilization of spring barely for malting purposes. The aim of this work was to compare two types of fertilization, areal and variable applications, variety Laudis 550. There were different pre-crops, the first option had corn and the second potatoes as a pre-crop. The result took place using field measurements of yield elements, laboratory measurements and economic evaluation. In the final assessment of the data from this experiment, it was found that variable applications of nitrogen fertilizers are a positive agrotechnical procedure in spring barley. Variable applications result in higher yield and malting quality.

Industry 4.0 in Agriculture
ŠVEPEŠOVÁ, Ivona
This Diploma 's thesis is focused on a new technology in agriculture which are provided by Industry 4.0. The aim of the thesis was to evaluate the use of Industry 4.0 in agricultural companies, its technologies, start-ups and projects. Then, based on the findings, devise recommendations. Industry 4.0 is in Agriculture called as Precision Farming or Precision Agriculture. In general, Precision Agriculture is a farming management concept based upon observing, measuring and responding to field variability and aspects of animal rearing. It also has the potential to optimize yields, increase corporate profits and at the same time reduce the negative environmental impact of agricultural activities. The first part of the thesis focuses on Industry 4.0 and competitiveness, as well as farming methods, technologies and projects which are implemented in plant and animal production. The second part is focused on the real evaluation of the current situation in the Czech Republic through a questionnaire survey. Using a questionnaire completed by over a hundred respondents, we are given a detailed overview of using Precision Farming in agriculture companies. The last part uses the statistical method, public researches and defines strengths and weaknesses of using Smart technologies. Based on this evaluation proposes recommendations for agriculture companies those who already use Industry 4.0 technologies, or those, who are hesitant to use it for the time being.

Porovnání precizního a konvenčního zemědělství na daném pozemku
POSPÍCHAL, Tomáš
The bacherol's thesis examines the difference between conventional and precision agriculture in tillage and their impact on work efficiency. It focuses tillage methods, guidance systems, conventional and precision agriculture. The practical part of the work compares the impact of conventional and precision agriculture on fuel comsumption, area performance, prime and secondary time on given plot divided into two parts.

Porovnání vybrané sklízecí mlátičky v konvenčním zemědělství a v precizním zemědělství.
VALENTA, Pavel
The diploma thesis on the comparison of the harvest of cereals using the combine harvester in the quality of work is based on the technical literature review, which describes the individual parts of the combine harvester from the harvesting adapters to the threshing device. The methodology of this diploma thesis describes the procedure by which the results and values for the comparison of the Class Lexion 770 TT combine when working in manual control and GPS control (Global Positioning System). Measured, calculated and compared values obtained according to the 2019 methodology. Harvesting of grain crops using the combine harvester is compared in terms of harvest efficiency, harvest losses, machine throughput, performance balance and fuel consumption. The thesis also includes basic economic operating costs.

Porovnání vybraných secích strojů v konvenčním a precizním zemědělství
KRÁSNÝ, Lukáš
This thesis is divided into two main parts. The theoretical part, which contains a brief introduction to sowing, a description of the seed drills that are used for data acquisition, an explanation of the GPS (Global Positioning System) and how these devices work.The second part is the practical part, which deals with the comparison of performance and economic parameters of operation of two selected machines used for seeding, where one is guided by GPS and the other manually.

Mapování pohybu zemědělské techniky s využitím a bez využití GPS
HAŠKOVEC, Luboš
In the thesis the GPS technology is described and functionality of the system is explained. The power and the economic parameters of selected agricultural sets are compared. In theoretic part of the thesis the technology of a global navigaton systems, fundamental principles of its working and its agricultural utilization are described. In practical part of the thesis two control systems via GPS navigation and manual control, respectively, are compared. Measurement was provide on the John Deere 8320R wheeled tractor in agregation with the Strom Terraland TN 3000 H chisel plow in tillage and on the John Deere 8420 wheeled tractor in agregation with the Lemken Solitare 9 seeder in sowing, respectively.
