Cultivation of fodder sorrel for biogas production
Usťak, Sergej
The aim of the methodology is to provide farmers, agricultural consultants, operators of biogas plants and all other interested persons basic information about growing and processing for biogas of a promising non-traditional energy crop - fodder sorrel (Rumex patientia L. x Rumex tianschanicus A.Los.). Until now a comprehensive methodology for cultivation of this crop for biogas production hasn’t been processed. The methodology provides basic botanical characteristics of the crop, specifies soil and ecological requirements in habitat, describes the agricultural technologies of seeding, cultivation, fertilization, plant protection, harvesting and ensiling this crop for biogas production and provides their economic evaluation.

Possibilities of cultivation of cup-plant Silphium perfoliatum L. for biogas production
Usťak, Sergej
The aim of the methodology is to provide farmers, agricultural advisors, providers of biogas stations and anyone interested in growing and processing of agricultural biomass as a renewable source of raw materials and energy the basic information about a prospective non-traditional crop – cup-plant Silphium perfoliatum L. Up to now, a comprehensive methodology for cultivation this crop in conditions of the Czech Republic is not processed. The publication provides basic botanical characteristics of the crop, specifies its soil and ecological habitat requirements, describes the agricultural technologies for seeding, cultivation, fertilization, plant protection, harvesting and post-harvest treatment and gives an overview of potential productivity and main utilization possibilities, especially for biogas.

Design, verification of functionality and technological evaluation of heating plant farm grain.
JANIŠ, David
The main aim of this thesis is the design, verification and evaluation of machine lines for alternative heating plant farm grain. This work presents a fuel produced from biomass as a renewable resource with regard to the protection of the environment and its subsequent combustion for heating the facility. A mechanical design line for grain heating is described which is in Nová Včelnice Agricultural Cooperatives in Jindřichův Hradec. Another objective is to complete the economic evaluation of machine lines for heating grain.

Practical application of non market evaluation on example of public green on Prague 15
Adámková, Veronika ; Geuss, Erik (advisor) ; Branžovský, Antonín (referee)
The aim of this diploma thesis is application of non market evaluation on particular example of public green in Prague 15 and considering the possibility of using this method by public sector. Decisions of public sector aren't often transparent and systematic, in this study is proposed, how such a decision would be going on, if it was based on economic theory. First part of this study is concentrated on typology of goods, theory of non market evaluation and choice of the method applied on a particular example of a public green. Analytical part of this study contains description of application of contingent evaluation that estimates willingness to pay for a preservation and improvement of a public green. The last part of the study contains discussion of possibility of using this method by public sector.

Alternative utilising of agricultaral land resourses in light of economic also uneconomic aspects
STANĚK, Jaroslav
The development of countryside and agriculture is seen especially in competitive and multifunctional agriculture with an emphasis on improving environmental quality, which will underpin long-term economic growth and provide sufficient conditions for rural development in services and other activities. The main emphasis of multifunctional agriculture is therefore put on investment in agriculture, including support for young farmers and the processing of agricultural production. One of the urgent problems of contemporary agriculture is the effective exploitation of agricultural land resources, when on the one side the production (economic) function will be filled to the maximum extent as well as environmental and security features on the other hand. The thesis is focused on this issue, on this aspect has been designed and calculated variations of the use of land block naturally in the context of possible scenarios of related landscape.

Economical and environmental aspects of biogas station in Drahobudice
Pudilová, Pavlína ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
The topic of my master thesis is analysis of farm biogas station in Drahobudice. It is machinery, which processes agriculture crops and garbage from animal produce. From these substrates is produced biogas and burning of this biogas arises electric and thermal energy. This system of production from renewable resources is in accordance with demands of European union on reducing emissions from burning fossil fuels. This thesis contains overview of legislation relevant to given issue, describes development of this project, technical solution and process of operation. A part of this work also covers analysis of economic efficiency this investment and considers effects on environment. The main objective of my thesis is to identify, analyze and evaluate economical and environmental aspects of biogas station in Drahobudice.

Evaluation of production costs, revenues and quality of potato tuber in organic and conventional farming system
MALECHA, Pavel
In 2009, there was an experiment with strains of potatos conducted in the region of Soběslav, at an altitude of 614 m. The aim of this thesis was to evaluate production costs, revenues and internal tuber quality in terms of organic and conventional farming system. The work observed dry matter, starch, reducing sugar, chlorogenic acid, vitamin C, nitrates and solanine. An attempt was made on two different strains of potatoes which have different growing season (Impala - very early, Adela - early). Adela variant showed an average of 7.51 t / ha higher yield than the Impala. Higher costs per tonne of potato production were in the conventional way of cultivation. From the evaluation of the internal quality of tubers, there was an apparent influence of the strain and cultivation method on the content of controlled substances. The executed test showed the health of potatoes grown in an organic and conventional way.

Economic evaluation and risk analysis building technology
Krzyžanek, Michal ; Fotr, Jiří (advisor) ; Beranovský, Jiří (referee)
Thesis is intent on economic analysis and risk analysis building technology, used at reducing energy costingness. Basic goal of this thesis is evaluating selection energy - saving building technology for concrete investment project at authority two principles. First principle is complying with time influence namely how in view of financial resources, so in view of price energy. Second principle is consequential complying with risk and uncertainties particular factors. In case of these thesis it means simulation crucial factors as a stochastic model. To these purposes will be used method Monte Carlo. Theoretical part of thesis be engaged in characterization economics analyses and risk analyses investment project. Information betray into theoretic parts will applied on concrete investment project, reconstruction residential building using energy - saving technology that contribute by to decrease energy costingness of all building. Fundamental of the investment project is reducing costs on heat a hot water. Goal of practical parts this thesis is give to data for decision making house owners about reconstruction house, regarding particular building technologies.
