Potato Harvesting in Vysočina - radio reportage
Procházka, Adam ; Lovaš, Karol (advisor) ; Lokšík, Martin (referee)
This bachelor's thesis uses a radio reportage to show the process of harvesting potatoes on Josef Vlk's farm in Čelistná near Pelhřimov. In the first, theoretical part, the topic of reportage as a radio genre is mentioned with the addition of its past and present. One chapter will also focus on the basic orientation of the potato harvest. The second half is devoted to the methodology of making radio reportage. It explains the preparation, recording procedure and subsequent post-production.

Evaluation of supplementary plant preparation application effect on potato production parameters
MIČKA, Michal
The aim of the master's thesis was to evaluate the effects of the application of an auxiliary product on the production parameters of potatoes. For this purpose, a one-year small-plot experiment was established in 2022 at the experimental field in Lukavec. The varieties Ornella, Red Anna, Val Blue, and Westamyl were selected for the experiment. For this experiment, the auxiliary product Energen Fulhum Plus was applied. Energen Fulhum Plus is a modified aqueous solution of substance salts obtained by the original decomposition of technical lignosulfonate. It supports the formation of fine root hairs and, as a result, increases the use of moisture and nutrition. It also supports growth, yield, and material composition. After the harvest of the experimental plots, the yield was determined and then samples were taken for chemical analyses. From the experiment, the tuber yield, average tuber weight, starch content, starch yield, dry matter content, nitrogen content, nitrogen yield, and polyphenol content were evaluated. In the monitored year 2022, the temperature and precipitation during the period March - September were above average and it is evident from the results that all the varieties increased the tuber yield (t/ha), average tuber weight (g), starch content (%), starch yield (t/ha), nitrogen content (%) and nitrogen yield (t/ha) compared to the control after the application of the auxiliary product Energen Fulhum Plus. As for the dry matter content (%) after the application of the auxiliary product, the dry matter content increased in all varieties except the Val Blue variety, which showed a slight decrease in dry matter content. The application of the auxiliary preparation had different results for the total content of polyphenols (mg EGA/g dry matter), it increased in the varieties Westamyl and Val Blue and, on the contrary, decreased in the varieties Ornella and Red Anna.

Applying new approaches in potato crop nutrition
RŮŽIČKA, Jan
The main objective of the bachelor thesis was to conduct a literature review in the field of fertilization and nutrition of the potato plant and to collect and sort information on new approaches used in potato cultivation. The thesis describes the methods of fertilization and nutrition with organic fertilizers, inorganic fertilizers (including essential elements) and their effect on potato growth and quality. Furthermore, the possibilities of using microbial and biochemical approaches to improve potato nutrition and their advantages or disadvantages are presented. The paper also presents opportunities to improve fertilizer use and minimize negative environmental impacts using new technologies and innovative practices. Finally, three practical examples from potato farms are presented.

Porovnání automatického a poloautomatického sazeče brambor
NEBESAŘ, Jan
In the bachelor thesis two technologies for potato planting are compared. The first technology is planting with an automatic planter and the second technology is planting with a semi-automatic planter. The measurements were carried out in the Highlands region, which is located in a potato production area. The work focuses on the comparison of technologies in terms of quality of work, area performance and economic efficiency. The latter includes the consumption of post-fertiliser materials and the operating costs of individual planters. Furthermore, the thesis seeks the point at which both technologies achieve the same area efficiency at the same machine operating costs.

Hodnotenie vplyvu odrody na kvalitu zemiakových lupienkov
Lovás, Patrik
The diploma thesis deals with the evaluation of potato variety impact on final chips sensory quality. Lab experiment was focused on three potato varieties used in INTERSNACK Choustník, a.s. production process, where dry matter, starch con-tent, reducing sugars and texture traits were evaluated. Lastly, chips´ sensory analysis made of given varieties was examined. Company secret did not let us re-veal the real names of potato varieties, so they are identified by Slovak alphabet letters: A, B, and C. The best sensory quality was measured in chips produced from B variety, characterised by suitable chemical parameters for chips processing. The other variates are suitable for chips processing as well, but the final chips´ sensory evaluation reported some irregularities, which could cause in C variety the higher content of reducing sugars, and in A variety agrotechnology issues.
