Evaluation of the yield and quality of table potato tubers
KAŇKA, Jakub
The aim of the diploma thesis was to evaluate the differences in yield, content of nutritionally important substances and table value of tubers in the selected set of ware potatoes. For this purpose, a small plot experiment was established in Jindřichův Hradec with 3 varieties of ware potatoes: Rosara, Sunshine and Princess. The cultivation took place under the conditions of conventional technology. During the vegetation, the health of the growth, the onset of growth phases and the yield formation were monitored. Samples were taken from the harvested plots for examination and chemical analysis and then the yield was determined. The number of tubers per bunch and stem, the average weight of tubers, dry matter content, starch content, total polyphenol content and antioxidant activity were evaluated for individual varieties. Furthermore, the table value of tubers was evaluated by evaluators through a cooking test.

Environmental aspects of japan poplar growing - greenhouse gases emissions
KAŇKA, Jakub
The aim of the bachelor thesis "Environmental aspects of japan poplar growing - greenhouse gases emissions" is to create a general overview of cultivation of fast-growing woody plants , specifically japan poplar, by literature study. Another objective is to elaborate a research focused on the environmental impact of its cultivation on greenhouse gas production, which is expressed by the production of carbon dioxide emissions (CO2 eq). For this purpose, the scope of all operations and interventions including the establishment, treatment and subsequent harvesting of the plantation was elaborated in the range of this thesis. Using these data, the total emission burden for the environment in terms of CO2 eq production resulting from the cultivation of energy crops was calculated in the SIMA - PRO program.
