Možnosti využití travních porostů v rámci agrolesnictví
Macek, Libor
The bachelor's thesis deals with the use of grasslands with a focus on grasses and clover in agroforestry systems. The first part describes the agroforestry itself – its characteristics and significance. Furthermore, emphasis is placed on woody plants suitable for agroforestry systems, especially in the conditions of Central Europ, as well as on their production and non-production functions. The most suitable representatives are for example, walnut (Juglans), poplar (Populus), but also less economically used representatives, such as cherry (Prunus) or rowan (Sorbus). At the same time, agroforestry is divided into certain units, which are characterized by their functions, both in the tropics and in Europe. The most typical systems in Europe are mainly silvopastoral systems, but also increasingly used alley cropping on arable land. The second part describes various agroforestry systems using grasslands as well as practical examples of functioning systems in different climate zones. Attention is also paid to individual members of the family Poaceae and Fabaceae suitable for their characteristic properties in these systems. The most important for shading appear to be tolerant representatives such as Agrostis stolonifera L. or Festuca arundinacea Schreb. from the Poaceae family or Meadow clover (Trifolium pratense L.) from the Fabaceae family. Possible interactions related to the coexistence of woody plants, grasses and clover, such as competition and allelopathy, are also not neglected.

The influence of natural conditions on the occurrence and movement of wild animals and the success of evaluating their detection using different working methods
POLENSKÝ, Jakub
This thesis aimed to determine the influence of landscape conditions on the occurrence and movement of wildlife and to evaluate the success of game detection using different methods, focusing on roe deer. Roe deer are our native game and are now one of our most widespread game animals. The entire dissertation was conducted to propose the most optimal way of searching for a game on agricultural land in front of hayfields using unmanned UAV technology with a thermal imaging camera. In order to achieve the aim of the thesis, several sub-steps were carried out, which mainly dealt with the issue of comparing the methods of deer detection in forage crops (ground survey versus the use of UAV technology) and the issue of returning the deer to the crops after they had been flushed out or carried away. Other sub-analyses included evaluating the effectiveness of alternative methods of scaring deer from stands using different types of scarecrows and assessing the occurrence of red deer on the land concerning the location of landmarks. The solution of the dissertation thesis resulted in the proposal of a methodological guide for optimizing the search for deer on forage plots on arable land and permanent grassland.

Konstrukční návrh 3D modelu obraceče píce pro výuku zemědělských předmětů
TOTH, Jakub
The thesis deals with the creation of a 3D model of a forage tedder, which can be used as a learning tool in teaching agricultural subjects. The model was inspired and created according to the model of a real forage tedder type SO 160. The student version of CAD program SolidWorks 2021 was used to create the 3D model. The theoretical part of the thesis deals with the issue of forage crops, including their distribution, harvesting conditions and harvesting procedures. The second chapter is then focused on forage tedders, where the different types are described. At the end of the first part of the thesis, CAD systems, their history and distribution are discussed and some selected types of CAD software are described. The practical part focuses on the creation and construction of a 3D model and the work procedure for creating the individual components together with their description.

Porovnání kvality řezanky u samojízdných sklízecích řezaček
HEŘMÁNEK, Aleš
This final thesis is dealing with feed production technologies interms of different species of plants for the purpose of livestock production or energetics. The thesis analyzes one particular technology because of wide range of options on the market nowadays. The resource review chapter provides comprehensive information about history of forage harvesters and their use in crop production up to now. A significant part of that chapter describes an overview of latest technology. The thesis focuses on self-propelled machines and is complemented by a description of individual technical solutions. The metodology part contains measurement procedure and comparison criteria of particular John Deere 8300 and New Holland FR 500 machines. All the measured values had been gathered between 2019 and 2020. These values have provided the main source for acquiring further subject. The points of comparison were feed quality, grain crushing, efficiency and fuel consumption. The last criteria in that comparison are operational costs of particular forage harvesters.

Stroje a strojní linky pro sklizeň pícnin
Práza, Martin
This thesis gives a description of technique utilization forage and methods about forage preservation. Next part presents the factors and opportunity of organization machinery to the machine line for ensilage. Practical part compares results of practical field experiment about self propelled harvester and various transport vehicles for transport cutter forage. The experiment monitored fuel consumption, engine hours, turnover time and transporting amount of vehicles which are then compared.
