Evaluation of losses during storage of potatoes in selected stock
PELÁN, Jakub
The thesis is focused on the storage of potatoes and packet loss during storage of seed potatoes. He designed an experiment in which the measured loss rates in five varieties (Atlantic, Lady Claire, Lady Rosetta, Saturn, Toscana). The experiment was conducted from late September 2013 to February 2014 in the potato in Vílanci. In the interval of two months were weighed and wrote down the value of each experimental varieties. Reviewed conditions for potato storage potatoes (especially storage temperature and relative humidity) and their effect on loss rates. In the end it turned out that the largest loss rate has a variety Atlantic and vice versa smallest loss has a variety Toscana. The most essential losses occurred in the variety Lady Rosetta and most unnecessary losses had Atlantic.

Growing potatoes and production trends
PETRŮ, Ondřej
My bachelor work is focused on utilitarian direction and changes in potato cultivation technology. The work is based on the available literature. Potato is a very important crop which is cultivated mostly for nutrition of the population. It is also cultivated as afood for folowing production of starch. The work processed 8 issues. It deals with history, describes different kinds of potatoes. It also deals with the particular utilitarian kinds of potatoes factors, causing new utilitarian trends creation in The Czech Republic. The following part is focused on technology changes in potato cultivation, as well as the role of a potato, of its usage and economy of growing of potatoes.

The fibre plant growing in Czech Republic
ŠÍMOVÁ, Barbora
This bachelor thesis deals with the cultivation of fiber plants in the Czech Republic, which are closely linked to the cultural history of mankind and agriculture. They are widely used in the textile and automotive, construction, food or cosmetics. Their main advantage is absolutely clean and waste-free use. As a result of the reduction of subsidies and import of cheap, mostly Asian, textiles there is a decrease in sown areas and declining production of flax and hemp. Growing these plants in the Czech Republic declined to the point of loss.

Effect of harvest interval from the end of the vegetation potato on the occurrance Rhizoctonia cancer
ZENÁHLÍK, David
The thesis on the topic of the influence of the time period distance of the harvest from the end of the vegetation on the occurrence of "potato fenkines on the bulbs." There were 11 varieties of the potatoes chosen for the observation. Their vegetation was terminated by the desication resource called Reglone. From the end of the terminated vegetation during 10 days until the harvest there were 4 samples taken and they were evaluated on the occurrence and it's percentage of the "potato flakiness on the bulbs" in accordance with the scale of Wenzel and Demel (1976). There were there varietes selected for the evaluation; Flavia (VR), Riviera (VR), Rosara (VR), Merida (R), Adéla (R), the Baccara (R), Marabel (R), Ditta (PR), Laura (PR), Maréna (PP) and Saturn (PP). The achieved results of the "potato flakiness" weere evalunted statistically. The aim of the evlution of the ("potato flakiness on their bulls") Rhizoctonia solani. The term of the vegetation termination depends on the grover and must be in written documentation. The harvest alome can follow after the the drawal period in the desiccation resource, which uswally 15 days. The results indicale that whem the harvest of the potatoes is made at the proper time after the termination of the vegetation, the potato bulls are withhout any largen percentage accurence of the "flakiness". The results achieved during the years 2012 and 2013 indicate that in early implementation off all the working operations important for the potato growing, which begin with sorting out, followed by plantig, care, chemical sprays, selection, parades, desiccation and the harvest, the "flakiness" dinďt exceed 5% of the occurence. Another results indicate that the taken bulls were undamaged and the difference of the occurrence of the "flakiness"on each sample appeared in a variety of ways. The years of abseving the experiment proved that there was an increase in the "flakiness" on the surface for a given time period.

Rust problems on selected forage grass species
HOSPODÁŘSKÝ, Radek
The object of this diploma essay is to evaluate selected breeding material sensitivity to attack of crown rust and grass rust. Research was realized in cooperation with Breeding Station Větrov, located in altitude 630 meters above sea level, district of Tabor. Attack of the plants was rated according to scale used by UKZUZ1-9. During vegetation period attacked parts of the plants were collected for specific rust diagnosis. The results were evaluated using statistical data elaboration.
