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.

Spalné teplo a výhřevnost vybraných energetických trav stanovení na základě elementární analýzy
SEDLÁKOVÁ, Aneta
Renewable energy sources are largely represented by biomass energy, which is then used in many ways. Among the most common are the phytomass direct combustion to heating. For these purposes, in many cases growned Reed canary grass, which could compete with other, more efficient energy grass Szarvasi -1. Aim of this work is to compare the suitability of selected energy grasses (Phalaris arundinacea L. and Elymus elongatus subsp. Ponticus cv. Szarvasi-1) for purposes of direct combustion in terms of the energy yield of the unit of production and unit of area under various intensities of fertilization.

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.

Growing of energy crops - yield parameters
NĚMEC, Václav
Thesis deals with renewables resources, potential of biomass and plants phytomass. We focused on the cultivation of selected energy crops, as perennial grasses Elymus elongatus (subsp. ponticus, cv. Szarvasi-1), reed canary grass, miscanthus sinensis and annual crops of maize and sorghum. The practical part is aimed to the establishment of small plot trials with a variety Szarvasi-1, reed canary grass and miscanthus. We described the methods of field experiment establishing with crop Szarvasi-1 of their treatment and harvest. The results of our own experiments we compared with the literature data. The last part deals with the economy of growing selected crops.

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.

Environmental aspects of energy crops growing - production of CO2eq
HOVORKOVÁ, Sandra
The task of the thesis: " Environmental aspects of growing energy crops - production CO2 eq " is processed agricultural engineering literature review summarizing selected cultivation of energy plants ( Reed canary grass - Phalaris arundinacea ) and its growing impact on the environment with a focus on the production of carbon dioxide (CO2). The content of their work is to create a framework for calculating emission load growing canary rákosovité in terms of CO2 in the SIMA - PRO.
