The present diploma thesis deals with evaluation of changes in the cost of cultivation of peas, characteristics of surveyed commodities, identifying changes in the crop areas and yields, the price level of commodity peas. The theoretical part describes the agrarian sector and its current form. It also characterizes investigated commodity peas and the individual cost items. The analytical part summarizes the development of Czech agriculture, particularly crop production. It also focuses on the development of price levels pea agricultural producer prices. The next section is an analysis of the development and structure of the costs of planting peas.

In the last years the current energy crisis in Chile has led to consider different sources of renewable energy, where forest biomass from fast growing plantations play a important role. The aim of this study was to find suitable land areas (gross and net) for the establishment of wood energy plantations in Ranco province in Chile, following the methodology proposed in the thesis of forest engineer Federico Anderfuhren, where different criteria and restrictions were set using as a tool geographic information system (GIS). The results showed a suitable gross area of 141.889 ha (17%) and a net area of 46.350 ha (6%) of the province. It was conclude that the coverages with the greatest influence obtaining the gross area were water bodies and protected native forest and obtaining the net area, land use capacity (II, III, VII and VIII) and erosion land potential.

Aim of this diploma thesis is calculating the carpet area/built-up area coefficient and make a proposal how to put this coefficient in place in building evaluation field. Also, assessment of error rate of this method is needed. More methods were suggested based on differently calculated coefficients. Comparison of different sources of public information about buildings was made and these were compared to actual state of the buildings. Research was made whether there is correlation between age of the building and tipical building´s characteristics in examined area. Studied area is called Kluky (part of Hradec Králové).

The diploma thesis provides a comparison of market prices of type family houses of the 50 main suppliers of timber buildings in the Czech Republic. The buildings are divided into the certain categories as per list of manufacturers and suppliers of timber buildings 2017. A comparison is made in a format of charts according to the individual categories related to built-up, floor, residential area and enclosed area. Furthermore, a comparison with JKSO for year 2017 is carried out.

The thesis deals with determining the quotient of usable area and the built-up area for houses in a specific location and analyzes the influence over size of quotient according to variables in process of determining.

This thesis is engaged in the technical possibilities used in maintenance of greenery. The thesis gives a definition of the term "green vegetation," explains the dividing of greenery in different constituents, and describes the main work stages throughout the year. There is a list and description of instruments and technology for maintenance of greenery included in the thesis. The theoretical part of this thesis is engaged in founding of garths, is in detail focused on the maintenance of garths and on characteristics of instruments which are used for mulching on flat and sloped areas. The latter portion of the theoretical part of this thesis mentions the topic of the maintenance of trees and how they are categorized according to how they are pruned. The practical part of the thesis monitors the metering and evaluates the acceptable technical economic indicators of reapers and harvesters. The target of the practical part is to obtain data in order to compare the effectiveness of different horticultural tools. The comparison of these instruments is included.

This thesis deals with the evaluation of defoliation of vineyards with respect to determination of extent of leaf area reduction in the varieties Hibernal, Zweigeltrebe and Cabernet Moravia. The experiment was conducted in 2013 at the experimental sites in the cadastral area of Lednice in Moravia and Rakvice. The development of leaf area was evaluated by ADC device BioScientific Ltd. during three periods (June, July, August) in the phenological stages of flowering phenological stages of fruit development and ripening of the fruit phenological stages. From the measured data was determined leaf area index (LAI) and the extent of defoliation. Using analytical methods parameters of quality grapes were evaluated - the sugar content, pH, acidity, assimilable nitrogen, and others in order to determine the optimal time of reduction in leaf area of a vine. Part of this work was also the evaluation of operating costs for Defoliator.

Importance of precise estimation for tree biomass in forests has been continuously increasing. Regarding to the climate change, scientists have started to quantify all tree components not only in terms of energetic utilization but also for carbon stock estimation. Increasing relevance of biomass models for young trees relates to expanding area of young forest stands during the last period due to decay of old forests often caused by disturbances (especially: windstorms, outbreaks of bark beetles, drought episodes, and forest fires). Models for biomass stock estimations constructed for stands with age to 10 years are rare and usually are focused on aboveground tree parts. Thus, this work aims at filling knowledge gaps in this field. Its main objectives are: 1) construction of regression models applicable for estimation of dry mass in the particular tree components (i.e. stem, branches, foliage, roots) for young stands of some broadleaved species, 2) implementation of regression models for calculation of biomass conversion and expansion factors (BCEF), allocation coefficient, growth efficiency and leaf area index (LAI) and their inter-specific comparison, 3) utilisation of allometric relations for estimation on forage potential for ruminating ungulate game (i.e. browsing and stripping). To make up the models, destructive tree sampling will be implemented. The sample trees will be excavated, separated into tree components, dried for constant weight and weighed. Log-transformed relationships will be used for construction of regression models.

This diploma thesis was solved in Niklův vrch and Rennerovy boudy, areas located in the eastern part of The Krkonoše Mountains National Park. The main aims of this work were vegetation survey and description of environmental factors by Ellenberg indicator values of meadow areas contaminated by leaked sewage and meadows in their vicinity (referential areas). Another objective of this study was to determine soil pH, acceptable phosphorus and total nitrogen content and heavy metals amount in soil samples. Based on all collected data was proposed future management for each area. The negative influence of leaking sewage on meadows in Niklův vrch wasn´t confirmed, because of their highly effective cleaning by three-compartment septic tank and biological filter before discharge into surface waters. Leaked sewage loading was demonstrated in Rennerovy boudy, but only in the area just below the septic tank. The reason of the loading is unsatisfactory condition of the septic tank itself (change to cesspool by blinding discharge and sunken cover). This area was characterized by low species diversity, which is connected with the lowest number of plant species found there (12 species). Based on the habitat of dominant nitrophilous species Urtica dioica and species with nitrophilous tendencies (Alopecurus pratensis, Geranium sylvaticum and Chaerophyllum hirsutum) was determined association Rumicetum alpini Beger 1922 here. Soil from the area affected by the leaked sewage was characterized by the highest pH/KCl and total nitrogen content and also increased contents of acceptable and total P and K compared to other soil samples. To suppress this undesirable community Rumicetum alpini Beger 1922 is particularly necessary to improve the process of purifying leaking sewage by replacement the cesspool for household wastewater treatment plant. The distribution of this community also affects the absence of management. Therefore, it seems necessary to renew one-year mowing by scythe of this area.
