The table value of tubers from organic and conventional potato growing system
BOUŠKOVÁ, Michaela
The objective of this thesis was to assess the potato varieties produced by ecological and conventional farming, to find out the deviations of cooking types and to establish the cooking quality of the tubers The cooking quality of potatoes was established subjectively, based on sensory analysis. The individual characteristics of the cooking quality which were assessed included the colour of flesh, consistency, texture, flouriness, moisture, taste, and tuber darkening after cooking. The results suggest that the characteristics of the cooking quality depend mostly on the variety. The year of growth and the ways of farming also form a minor influence. The deviations of the actual cooking type of the assessed varieties from the declared cooking type were established according to the method of the Czech Agriculture and Food Inspection Authority. The results of the assessed varieties show that the cooking type was not affected; minor differences were caused by the year of growth.

Critical evaluation of potential of harvested product proteins in selected crops from perspective of their use in food and biotechnological applications
BUCKOVÁ, Pavlína
This diploma thesis deals with plant proteins. Literary review discusses the properties of the major proteins in selected agricultural crops (wheat, barley, oats, corn, peas, soybeans, canola, potato, Jerusalem artichoke) and their use in food, diet, biotechnology and other industries. The diploma thesis was also assessing the potential production of proteins in these crops on the basis of literature and available statistical data. Data is organized into tables and graphs

The responce varieties of potato at desiccation
ZENÁHLÍK, David
Bachelor's thesis deals with the reaction of potato varieties as desiccant in the seed crop to. The aim of the work was the monitoring of early vegetation for selected varieties in the seed stands, if there is no occurrence of obrostů, which in 2011, although strong growth were not noticeable even on the areas of seed and ware potatoes. He was also monitored the incidence of flakiness on seed varieties and that the variety of Impala, Rosara, Adele, Marabel, Princes, Ditta, Laura, Belana, Baccara, Marena. The relationship of the term dedikace and the harvest and the reactions of selected varieties Ditta on the effectiveness of desiccation of the substance and another Basta15 the absence of Reglone to obrostům and desiccation substance is more efficient. The results obtained for varieties in 2011. According to the scale of the VÚB Havlíčkův Brod for the evaluation of the occurrence of flakiness tubers (Rhizocotonii solani) is given the percentage representation of vločkovitosti on tubers of potatoes. Data were obtained from his own assessment in the Košetice Agropodnik, a.s. in the reference year 2011 was assessed a total of 10 varieties on the occurrence of the flakiness and reactions of selected varieties Ditta on the effectiveness of the desiccation of the substance and another Basta15 the absence of Reglone to obrostům and desiccation substance is more efficient.

Biology, occurrence and control Cockspur Grass(\kur{Echinochloa crus-galli} (L.) Beauv.)on arable land
VITURKA, Martin
This work is focused on the occurrence of Cockspur Grass (lat. Echinochloa crus-galli) on arable land and ways and means of its regulation. Damages which are annually caused by weeds are very difficult to quantify and their negative impact is reflected every year in all crops and all fields. Cocksour Grass belongs among the most dangerous weeds, especially in wide-row stands. Furthermore, I focused on the issue of late weed, seed dormancy and resistance of populations. A related question is possible solution to the protection of stands against weeds using both preventive and direct methods of control plants. An experiment was made to check influence of herbicides on the population of Cockspur and other weed species which occur in this root-crops. The result showed which kind of herbicide is more effective with pre-emergence application to Cockspur Grass and other monitored weeds.

The influence of leaf fertilizers at potato yield
KULÍK, Jan
The aim of this thesis is to evaluate the influence of leaf fertilizers at potato yield. The main advantage of leaf nutrition is speed of an action on a plant, possible combination with other interventions (application of fungicides) and economy of use. Leaf nutrition promotes tuber yield and quality, mainly in their tuber set and poor growth conditions. It is important to perceive leaf nutrition as a suplement nutrition because it is no substitute for root nutrition. The field experiment was established on the land of the University of South Bohemia in České Budějovice in 2011. There were used selected varieties of potatoes with different growing season. Very early variety Magda, early variety Adéla, semi-early varieties Laura and Satina and serotinous variety Bionta. The experiment was comprised of four variants and in four replications. There were used liquid solution of urea, Lignohumate and Lignohumate with NPK for fertilizer of variants 1, 2 ,3. Control variant was without aplication of fertilizer. There were evaluated proportion of grow-up plants, tuber yield, proportion of ware size tubers, the number of tubers per plant, the average weight of one tuber, the average weight of ware size tubers and starch content. It was found out using of liquid solution of urea increased tuber yield of all selected varieties. The highest yield of varieties Adéla and Laura was achieved by application of Lignuhumate, the highest yield of varieties Satina a Bionta after using of liquid solution of urea. Very early variety Magda was not too responsive to application of leaf fertilizers excep using of liquid solution of urea.

Evaluation of tuber cooking quality in selected table potato cultivars cultivated under organic and conventional crop management
ŠPLÍCHALOVÁ, Veronika
The aim of this diploma thesis was to evaluate the effects of conventional and organic crop management on cooking quality of potatoes. In one-year potato field trials (year 2010) with different crop management (conventional versus organic), 13 table potato genotypes (Adéla, Bionta, Karin, KE 100/10, Laura, Madona, Magda, Princess, Red Anna, Rosara, Solara, Satina,Terka) were used. The cooking quality (i.e. colour of the flesh, consistency, mealiness, moistness, flavor and darkening) was subjectively assessed using sensory analysis according to VORAL (1996) method. Only structure of boiled potato tubers was significantly affected by different crop management (4.8 % from total variability). Genotypically declared cooking types in used potato genotypes were confirmed in both production systems.

Reaction of certified seed and farming seed in selected variety potato
VANĚK, Petr
The main aim of this bachelor work was influence of certified seed and farmer seed in selected potato varieties. In 2008 attempts were established with certified seed and farmer seed. The selected varieties were evaluated by the number released plants, production of potatoes, proportion of market tubers and starch kontent in tubers. Comparisons were 4 varieties with different lenit of growing season {--} Magda, Adéla, Ditta, Bionta.

Monitoring of fulfillment of consumption basket in the selected kindergartens
ZIMMELOVÁ, Veronika
The main aim of the Bachelor thesis in the theoretical part was to outline the issue of boarding in kindergartens, to explain the term ,,consumption basket`` and subsequently to provide analysis of single parts of the consumption basket in regards to its benefits for the organism of a child. In the practical part, the explanation on the principle of calculation of consumption basket is given in the first place. The main aim of the practical part is then to analyse consumption basket in selected kindergartens and carry out, based on the selected criteria of classification, evaluation of fulfillment of consumption basket in the respective kindergartens.
