Cultivation of reed canary grass Phalaris arundinacea L. for biogas production: methodology for practice
Usťak, Sergej ; Strašil, Zdeněk ; Váňa, Vojtěch ; Honzík, Roman
The basic aim of the methodology is to provide farmers, agricultural advisors, providers of biogas plants and anyone others the basic information about growing and processing for biogas a prospective non-traditional crop - reed canary grass Phalaris arundinacea L. Up to now, a comprehensive methodology for cultivation and utilization of this crop for biogas production 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 ensiling and gives an overview of potential yields of biomass and biogas, especially methane including their economic evaluation.

A possibilities of use of Phalaris arundinacea for energetic utilisation
VACEK, Martin
The aim of my thesis was to compare selectid allotment, Botanical composition of allotmnet and prortion were monitored. Assessment of medium water content in soil. For parametrs of burning was to find number of fertile and sterile culm. In literal research are summarized common data about biomass and particular grass used for energetic purposes. Detailed description of reed canary grass and its description, agrotechnology and harvest. It is also important to mention processing of biomass in to the shape briquet and pelets. In the last part of research is description of burning device for used biomass. The practice part description to optain sample particular lokalities and these results and compares them.

Environmental aspects of energy crops growing - production of CO2eq
PÍSAŘÍK, Martin
This thesis deals with the partial evaluation of the life cycle of three kinds of power plants, particularly flint corn ( Zea mays L.) , reed canary grass ( Phalaris arundinacea L.) , Szarvazi I ( Agropyron elongatum L.) and their environmental impact during their cultivation. As an evaluation framework was used seedbed preparation time from the first year to the last harvest after ten years growing cycle. To calculate the emissions of greenhouse gases has been used software tool SimaPro . The aim was to find out how much greenhouse gas emissions (kg CO2eq per 1 kg of dry matter ) is created in the cultivation of selected power plants and compare that plant is from an environmental point of view the most environmentally friendly. The total emission load produced during the life cycle of corn is sown CO2eqv 0.199210 kg per 1 kg of dry matter , with reed rákosovité CO2eqv 0.182075 kg per 1 kg of dry matter. I Szarvasi is from an environmental point of view the most friendly CO2eqv produces 0.110232 kg per 1 kg of dry matter.

SEASONAL DEVELOPMENT OF ABOVEGROUND BIOMASS AND LEAF AREA INDEX IN A SELECTED MONODOMINANT STAND OF EUTROPHIC WET MEADOW
RYCHTEROVÁ, Jana
The bachelor thesis is part of the project of Ministry of Enviroment of the Czech Republic entitled CzechCarbo {--} the Study of the Carbon Cycle in Terrestrial Ecosystems of the Czech Republic, which is coordinated by the Institute of System Biology and Ecology of the Academy of Sciences of the Czech Republic. This work is part of team research focussed on aboveground production of a eutrophic herbaceous wetland, the Wet Meadows near Třeboň, where the carbon balance and cycle are studied within the CzechCarbo project. The work deals with aboveground production and leaf area index in Phalaris arundinacea (L.), which dominates the vegetation in the seasonally flooded part of the Wet Meadows. The studied stand dominanted by Phalaris arundinacea is highly productive. Its annual aboveground production attained 1407,6 g.m-2. The highest value of crop gropwth rate (CGR), attained in May, was 10,67 g.m-2.den-1. In the same time period, the relative growth rate (RGR) was 56,9 mg.g-1.den-1. The results gained in 2006 are discussed with results of previous research focused on the biomass and production of P. arunadinacea in the Wet Meadows and other localities in South Bohemia.
