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.

Návrh moderních technologií pro vybraný zemědělský podnik
LÍVANEC, Lukáš
The diplom thesis shows the trend of modern agriculture. Describes precision agriculture its advantages and benefits. It also focuses on elements of precision agriculture, such as global navigation systems, variable applications, dose control by measuring the content of substances in a given commodity, software solutions for field and machine management and the principle and function of machines for the application of plant protection substances. In the main point, he analyzes the machinery of the Chyšky Agricultural Cooperative, where he selects the weakest link and proposes a new suitable technology for the existing one, then evaluates everything economically.

Možnosti využití online senzorových systémů pro variabilní aplikaci dusíkatých hnojiv
Škrabal, Jakub
This bachelor thesis describes the possibility of using spectral measurement of nitrogen fertilizers in variable application especially on winter wheat. The theoretical part describes the fashion and the principle of spectral measurement and the essence of nitrogen in field´s crop nutrition. This part also lists sensors available in the market. In a practical part of the thesis there is a description of operational experiment in which the Isaria sensor from Fritzmeier company was tested. This sensor has been tested for two years on winter wheat. In a argumentative part of the thesis there is a comparison of the results from this two experimental years and the evaluation of each variant of the sensors setting. The focus was specially on the following indicators: quantity of applied nitrogen, the utilisation´s efficiency of nitrogen on production unit and the content of nitrogen´s substance in grain and yield. Moreover there are mentioned the economic effects of the difference in uniform and variable dosage of the nitrogen fertilizers.
