Hodnocení vitality travních porostů v městském parku Koliště
Vrbová, Denisa
During the vegetation period of 2018, grass areas in the Koliště Municipal Park in Brno were monitored in order to verify the effect of the selected maintenance management on their condition. Two experimental habitats were selected in the park according to the type of maintenance, namely mulched grass and mowed with harvesting. The data and results show that mulching has a positive effect on grassland quality. The unsuitable height of mowing in the mowed grass was negatively affected by the appearance and health of the grass area.

Management trvalých trávnych porastov v územiach so zvláštnym ochranným režimom : metodika obnovy trávnych porastov /
Frei, Ivana
Four methods of grassland restoration on arable land using species-rich seed material harvested directly in the source Bromion meadows (Vojšické louky, Bílé Karpaty protected landscape area (PLA), Czech Republic) were compared. Species composition of established grasslands was evaluated through the vegetation development. The restoration methods comprised of i) green hay application, ii) sowing of seed mixture obtained from brush harvester collecting once in the vegetation period, c) sowing of seed mixture obtained from brush harvester collecting three times during the vegetation period per site and d) spontaneous succession were compared. The experimental plots were established in the surroundings of Malá Vrbka (Bílé Karpaty PLA) in 2009. Species composition and vegetation cover were recorded in 16 m2 plots in spring and autumn of 2010 and 2011. Altogether 144 releves were statistically analysed using direct (CCA) and indirect (PCA) gradient analysis; cluster analysis (Statistica for Windows), and Simpson, Jaccard and Sorrensen similarity coefficients. Species composition was significantly affected by the plot establishment period which explained 49.6% of variability in the species data set. Species composition was also affected by used restoration method. However, the restoration method had no significant effect on the plant species richness.

Využití přírodních extraktů pro zlepšení kvality travních porostů
Grydzhuk, Vitaliy
In teoretical part of this thesis are described setting of lawn and his maintenance. In this thesis are listed basic species of grasses which are contained in grass mix and fertilizers which were used during practical experiment. Due to the uniqueness of this experiment, literary research contained only basic information about natural extracts. Practical experiment consisted of preparing soil, setting up a lawn and followed by aplication of natural extracts and fertilizers. During experiment was monitored seed germination, weight of biomass in two period, colour spektrum of leaf surface and lawn condition. Results were monitored in four varietes and each of them was performed in 3 repetitions. The best results of germination was monitored in variety 2 (Extract). The ideal development of biomass was monitored in variety 3 (Extract + fertilization).

Vliv vápnění na druhovou skladbu a výnosy polopřirozeného travního porostu
Sláma, Miloš
Between 2014 and 2015 was monitored the influence of liming and N fertilization on dry matter yield, floristic composition, species diversity and quality semi-natural grassland at the experimental flat Kameničky. The experimental plots were arranged in four repetitions and divided into not limed and limed blocks. For the purposes used liming ground dolomitic limestone. Nitrogen in the form of urea was applied at doses N0, N50, N100. Species composition affected all indicators monitored permanent grassland, while also have an influence on yield formation. Nitrogen fertilization without other nutrients to the experimental flat Kameničky did not manifest into higher yields, higher species diversity and quality of the grassland. N fertilization increased portion of more valuable grasses at the expense of other herbal, but put down (P<0.05) representation intergeneric hybrid Festulolium pabulare. Liming had an impact of plant species which have been adapted to the acidic environment and also not increased yields. In species composition increased (P<0.05) representation Festuca rubra L., Agrostis spp. that have low requirements on nutrients and there were no (P<0.05) Alopecurus pratensis L. and Ranunculus repens L. Liming not caused higher diversity and not caused the quality of grassland.

Analysis of the structure and function of selected machinery company SECO GROUP for the mowing and maintenance of grass
Kinčl, Jan ; Krupička, Josef (advisor) ; Petrásek, Stanislav (referee)
The works aim is to analyze the structure and function of selected machines for mowing and maintenance of grasslands for the selected compani, comparing their characteristics and performance with selected competing products on the market. Part of this analysis is familiarization to maintenance and mowing of grasslands to create a basis for evaluation of the functionality of these machines. The work also marginally presents the history of the chosen manufacturer Seco GROUP Inc. Jicin and its scope of manufacturing activities. Another part focuses on the analysis and comparison of three selected products and comparing their quality and overall utility value to the products of competing producers in properly selected models and similarly constructed products to those produced by the company Seco GROUP. The goal is to evaluate the company's products in the category of small machinery, including an assessment of their suitability and shortlist the positives of the products against other competing firms.
