Pešek, Marcel ; Lukášová, Karolína (advisor) ; Holuša, Jaroslav (referee)
Pikonema scutellatum is a species with high outbreak potential, which caused local outbreaks in several areas in Europe during the 20th century. Within our research we observed an abundance of the spruce sawflies P. scutellatum at 10 predetermined locations around the Czech Republic in 2015. We used Malaise traps of Towness (1972) type for catching adults from late April to late June. P. scutellatum was detected in 9 of 10 sites with a total of 55 individuals. Which is lower than the previous collecting period in years 1999-2006, but it was not statistically confirmed (Kruskal Wallis test; p>0,05). There was more males then females but this also was not statistically confirmed (Wilcoxon matched pairs test; p>0,05). The flight activity period of P. scutellatum started in May and during June declined significantly. Population densities of observed species are very low and the population is in the latent phase.

Properties of selected varieties of tall fescue and their utilization for Lawns
Zachař, Jakub ; Svobodová, Miluše (advisor) ; Klára, Klára (referee)
Grass and its cultivation is being explored in breeding and maintenance for many years. The theme of this thesis is the evaluation of fifteen varieties Tall fescue (Festuca arundinacea Schreb.), which is a hardy robust species with short underground projections, curled leaf composition, wide, very rigid, reverse side rough and shiny on the cheek and fluted leaves. It tillers extravaginal and creates a dense turf. Its great advantage is the strong root system and certain symbiosis (mutualism) with a fungus of the genus Endophyte Neotyphodium, making it resistant to a variety of stresses. The aim is to detect differences intervarietal Tall fescue (Festuca arundinacea Schreb.), Which the Czech Republic is not yet used in the monitored indicators (coverage, color, texture, height stand in a certain time interval, the overall impression). In the future, we can expect increased demand for socalled. low input lawn, because of their tolerance to drought, high and low temperatures and diseases, and especially due to the low need for inputs.
The next chapter describes the properties of each of the individual varieties of tall fescue ( Festuca arundinacea Schreb . ) , which are: Barcesar , Barfelix , Barlexas , Barleroy , Cochise , Debussy , Fine Lawn, Galatea , Kontiki , Olympic Gold , Rembrandt , Regiment , Starlett , Palladium and Zuzana.
An attempt was founded in late August of 2012 a demonstration and experimental plot in the immediate vicinity of the Czech University of Life Sciences in Prague Suchdol, using 15 varieties of tall fescue (Festuca arundinacea Schreb.). Each variety was planted on a plot measuring 1 x 1 meter (one square meter), while calibrating 35 g per m2 in triplicate. Only varieties Barfelix (BF) were sown only in duplicate. Values are obtained climatic conditions at a given for 2014, 2015 and the long term average. The average temperature for the year 2014 was 10.7 ° C and 2015 it was 10.8 ° C which shows that compared to the long term average for those two years the average temperature of almost 2 ° C higher. Annual precipitation for the year 2014 amounted to 571.4 millimeters, which is more than 45 mm more than the long term average, but the annual rainfall for 2015 was only 370.6 millimeters, which is more than 200 mm less than the long term average . 2015 is generally ranked the driest years ever. Measurements were taken every 14 days and a total of 8 measurements were performed, the first measurements were made on 21 May 2015. Since that date, followed by
a total of 5 measurements, namely to July 21, 2015. After that date, followed by a nearly two month break because of the long lasting droughts. For individual varieties of tall fescue were performed in triplicate measurements of height increase in the crop, according to the method EN 735 933 determination of sward height of natural turf. Furthermore, coverage was measured (resistance to weed) according to method EN 735 930 Method C using the points of the frame. Spot frame was in this case replaced by a string measuring 100 cm long split 5 cm, whereby on each parcelce 1x1m were two repetitions.
Results were evaluated using the statistical program ANOVA (LSD, "alfa" = 0.05). Varieties of Paladium (88.3%), Kontiki (87.5) and Zuzana (87.5%) had the highest coverage demonstrably compared to all other varieties. On the contrary, the worst results in a variety of coverage reached Debussy (82.5%), Barfelix (83.3%) and Regiment (83.3%). Conclusive were the differences between other varieties. Olympic Gold varieties (85.8%), Barleroy (85.8%), Cochise (86.7%) and Barcesar (86.7%) were Although demonstrably inferior varieties of palladium, Kontiki and Susan, but also have a palpably better than varieties Barlexas (84.2%), Fine Lawn (84.2%), Starlett (85%), Rembrandt (85%) and Galatea (85%), but which were thus demonstrably better than varieties Debussy Barfelix and Regiment. Variety Fine Lawn conclusively reached its greatest values in growth rate and height above ground organs. When the average height was 6.4 cm in the dry season, however, showed no increase and vice versa suffered from drought, while significantly lowest results in this regard amounted to a variety of Paladium, which reached an average height of only 4.4 cm, which when mowing to 4 cm represents an average increase of just 0.4 cm. The varieties are fully resistant to stress, in the form of drought and high temperatures (Barfelix, Barlexas, Barleroy, Debussy, Galatea, Rembrandt and Starlett), less tolerant (Cochise, Zuzana) and some show no tolerance and conversely, suffer from drought (Barcesar, Fine Lawn , Kondiky, Olympic Gold, Paladium and Regiment). For all varieties was seen very good recovery after a stressful period.
It has been proven that the different varieties of tall fescue from each other in some respects differ , and a wide choice is thus able to fill in a diverse range of applications tall fescue all various environmental conditions or conditions of intensity of cultivation , while its use is possible in increasingly mentioned system low input grassland.

Economic Evaluation of the Operation of Game Management at the School Forest Enterprise in Kostelec nad Černými lesy
Strnadová, Martina ; Kupčák, Václav (advisor) ; Jan, Jan (referee)
The bachelor thesis deals with economical evaluation of the operation of game management. Thus how the School Forest Enterprise in Kostelec nad Černými lesy treats with resources invested to operation of game management. The document is particularly focused on the financial data of hunting grounds Bohumil and Radlice in years from 2013 to 2015.
At the beginning of this document are analyzed issues of game management, costs, revenues, hunting reports, beasts appreciation, damage and the protection of forest culture. The thesis informs about the organization of both the School Forest Enterprise and the Fishing and Game management Center. In the next part the accounting data and hunting reports of hunting grounds Bohumil and Radlice are analyzed in detailed graphical way.
The stress is put on costs added above the scope of commonly used for calculation of economic result from game management. It is focused on costs on protection of forest culture and on overheads which means on all own costs covering the game management operations.
The determined values are transferred to the price per kilogram for a piece of hunted and dead beasts. This will show how much has to be paid more for getting a profit when the costs are higher compared to the costs calculated previously.
Thanks to the complete analysis it has been discovered that according to the standard calculations the game management for ŠLP is profitable. This result is reached especially by the income from the sales of common hunts. The profit is getting smaller, when the overheads are included. In case of inclusion of the costs for the protection of the forest culture the result is even in red numbers.

Influence of bioeffectors application on phosphorus availability in substrate and on tomato yields
Beranová, Martina ; Kulhánek, Martin (advisor) ; Hanč, Aleš (referee)
In the past few years, the Czech Republic has been trying to increase the input of plant available phosphorus (P) due to the increasing its bioavailability in soil. From the point of view agriculture properties we can say that there is only little amount of readily available P in soil. Plants are unable to take up phosphorus sufficiently, which is mainly due to the fact it is part of various less soluble soil compounds. Therefore, there are new technologies aiming to make P more plant available. One of these technologies are so called Bioeffectors
The aim of this bachelor thesis was to increase the plant available phosphorus content in soil due to the bioeffectors application and therefore increasing tomato yield and quality.
The bioefectors used contained the following microorganisms: Trichoderma harzianum, strain T22, Bacillus amyloliquefaciens, strain FZB42 (RhizoVital), Pseudomonas sp. (pProradix) and a combination of Trichoderma harzianum with Bacillus subtilis with Zn and Mn added (CombiFector). The plant height, above ground biomass yields, tomato fruit yields and the contents of selected macro and micronutrients in soil (bioavailable form) and tomatoes fruit (total form) were estimated.
From the results is clear that: a) in the majority of monitored parameters, significant differences between treatments were not observed; b) Trichoderma treatment, in comparison to the Proradix showed significantly higher Mg content in soil, but only at the significance level 0.05; c) the total content of sulfur in the tomato fruit at the Trichoderma treatment was significantly lower in comparison with the Proradix and Combifector variations, and that at a significance level of 0.01.
In conclusion, it is possible to state that the application of bioeffectors, in the majority of cases, did not lead to significant changes of studied parameters. Therefore, it is necessary to look for new strategies that effectively increase the availability of phosphorus contained in soils and applied fertilizers. Therefore, it is possible to suggest further testing of bioeffectors in particular for further research in soils with varied characteristics and deeper microbiological analysis serving to understand the mechanisms of effectiveness and determine the viability of the products.

Using of unseparated digestate as a phosphorus source for garden plants
Kujanová, Denisa ; Kulhánek, Martin (advisor) ; Jindřich, Jindřich (referee)
The advent of the modern trend of renewable resources was inevitable culmination of the development of civilization. Mankind learns more about use inexhaustible resources compared to depletion of reserves of non-renewable resources. Providers of renewable energy sources also include a biogas plant, which main function is the production of biogas. Biogas is produced in reactors by process of anaerobic fermentation without oxygen. As input for an agricultural biogas plants organic waste, cattle manure or for example energy grasses are used. The process of biogas production has the leftover of the fermentation at its end, so called digestate. Its composition depends especially on the inputs.
Digestate is a compound with high pH which is very rich not only for phosphorus but also for other nutrients. There are many studies dealing with the theory and practice of using digestate on the field for improving its properties and of other digestate usage. This diploma thesis has aim to explore combinations of unseparated digestate with peat and dolomite limestone with an effort to create a suitable substrate for different types of plants in terms of accessible phosphorus content.
During the experiment following plants were used between the years 2011 and 2015: Gazania rigens, Ocimum basilicum and Mentha piperita. For a control substrates following variants were used: Different types of commonly used growing substrates as the controls; peat combined with unseparated digestate in proportions of 5, 10, 15, 20, 25 % volume. In selected years dolomite limestone was also added in doses of 3, 6, 10, 15 g/l to stabilize pH.
The results of the work show a positive effect of the digestate on the substrate properties as for example pH value (with possible addition of limestone for stabilization) or dry matter. Digestate appears to be a suitable source of phosphorus for plants. In terms of the above-ground biomass yield of plants reached its maximum value at the control substrate Gramoflor. From the tested substrates it was in the most cases the substrate with 10 % digestate (in two years with doses of 6 a 15 g/l). Highest percentage of dry matter reached usually the control substrates.

The maize growing in integrated farming system
VOKATÁ, Lucie
The main aim of this bachelor work is a summary about how to grow maize in an integrated system of farming. It includes utilization of maize in this system and effective protection against harmful factors. The work is made in a form of literary research. Maize has become an irreplaceable item of people's crop. It is used as feed and for industrial processing plentifully. Also its utilization as an energetic crop has started to grow recently. There is a range of maize crossbreeds which are determined to various climatic conditions with particular goal of growing and high income requirements. The diseases caused by different pathogens have been shown in the consequence of actions caused by unfavourable factors (such as change of climatic conditions, ways of soil treatment, greater substitute of maize in a sowing process, etc.). Also damaging these plants by pests is one of the significant problems to mention. Therefore the protective arrangements that do not overload the environment are necessary. One of these arrangements presents growing plants in an integrated system of farming. The integrated plant protection, as the main part of more intensive growing system, is reducing the usage of pesticides and it is supporting usage of non-chemical methods IOR. The core of the whole system is an effective protection against harmful factors, which provides regular profit and high quality of the agricultural production. Reduction of the risks and little influence of pesticides on people's health and the environment is necessary.Establishment of integrated plant protection is necessity arising from the regulation of the amendment for the law no. 199/ 2012 Sb. Observance of the principles for an integrated protection is compulsory for all professional users since January 1st, 2014.

Are Economics Etudents more Utilitarian than their Colleagues from other Disciplines?
Cinert, Vojtěch ; Houdek, Petr (advisor) ; Babin, Jan (referee)
The thesis analyses whether the students of economics reject utilitarian behavior less than students studying various fields than economics. The testing was carried out on the moral dilemmas of so-called "trolley problem". Data was obtained through on-line questionnaire, mainly from students of different universities. The results of the research point out, that in 2 cases out of 6, the students of economics and technical fields reject utilitarian behavior less. The dilemmas are both medical framing. The influence of self-selection was not proved. It is possible, that the studies of economics have an influence on evaluation of the utilitarian behavior.

Music as an Expression of the Lifestyle in the UK in 1960s. Contribution to the European Consumer Society after 1945.
Vlčková, Petra ; Soběhart, Radek (advisor) ; Kozmanová, Irena (referee)
This thesis focuses on the British music scene in the 1960s. Popular music was one of the main manifestations of consumerism and influenced the behavior of most young people. The aim of the thesis is to explain the extent in which popular music played a role in the establishment of a consumer society and, above all, the impact caused by interpreters and music groups on the lifestyle of their listeners and audiences.The thesis also examines how the British music developed in the Sixties and how it was characterized.The thesis is based on the assumption that the 1960s' is a key decade in the postwar history of modern society, a time when fundamental changes occurred in the value systems of most Western societies, notably the British. New generations of young people associated with economic prosperity surfaced at that time, fostering the development of the phenomenon of consumer society, thus changing people's lifestyles.The first part of the thesis is dedicated to economic and social assumptions of the development of the consumer society. The second part of the thesis addresses the social structure of the British society, focusing on the youth - arguably, the social extract that was most appealed by popular music. The core part of the thesis analyses the British music scene in the 1960s, with focus on the music groups and also the music industry and its impal on the lifestyle of youth.
