Starch and protein yield in potatoes for starch production
MIČKA, Michal
The aim of this thesis was to evaluate the starch and protien content in selected potato variarients in relation to nitrogen fertilization. The literature review is a general introduction to the given problem. In the year 2018, a one-year field trial was established where three starch yield varieties Anatori, Hermes a Ornella were observed. Nitrogen fertilizer was applied in two variants. The first variant was fertilized in the spring before planting with a dose of 73 kg N/ha, the second with a dose of 111 kg N/ha.In the experiment, tuber yield, average tuber weight, starch content, starch yield, dry matter content, and crude protein yield were evaluated. In the monitored year of 2018, which had above-average temperatures and on the contrary lowerprecipitation, the best evaluation was the application of higher nitrogen fertilizerswitha dose of 111 kg N/ha. Higher application of nitrogen fertilizers compared to lower dose increased potato tuber yield (t/ha), starch (%) and starch yield (t/ha).

The spring barley yield and quality in terms of selected agricultural company
KANTOR, Martin
This Master thesis deals with the yield management evaluation and malting quality of chosen varieties of the spring malting barley in terms of half-working experiment in company "Kantor Václav - Agricultural businessman". There was chosen a stand of experiment and the values of yield management were observed, especially the number of plants, their offshoots and spikes per square unit, the quantity of grains in spikes, the weight of a thousand seeds and the yield. In case of the grain quality elements was rated a content of nitrogen substances, the drop above the sieve 2,8, 2,5, 2,2 mm and under the sieve 2,2 mm, then the content of amyloid, germination and its energy as well as the grain moisture. Among the rated varieties were placed: Malz, Sebastian, Laudis 550, Kangoo, Xanadu, Sunshine, Bojos, KWS Irina and Pionier. The results were filed in the tables and charts. The influence of variety on a different yield element was found out in the final comparison of all parameters. According to the aspect of the yield elements as well as the quality, the best values in this year taking experiment were reached by the Kangoo variety.

Fertilization of table potatoes during vegetation solid form of nitrogen fertilizer and urea solution
PELÁN, Jakub
The thesis is focused on fertilization of the potato by leaf nutrition. The aim of the experiment was to evaluate how the selected varieties of potatoes respond on the application of leaf fertilizers. There were evaluated the effects of the application of urea, Energenu Foliar and Lignohumate NPK in varieties with different growing season Magda - very early, Adele - mid-early, Jasmine early to mid-early and late Laura. These varieties are evaluated by the proportion of emerged plants, tuber yield, proportion of consume size tubers, number of tubers in a bunch, the average weight of one tuber, number of stems per plant and starch content. From the results, it was found that all varieties responded positively to the application of leaf fertilizers. The effects on the potatoes were influenced by used variation of the fertilizer and by the different growing season of each potato variety

Porovnání kvantitativních a kvalitativních vlastností vybraných klonů odrůdy Sauvignon
Pokorný, Stanislav
The research in this diploma thesis aims on the comparison of quantitative and qualitative characteristics of selected clones of variety Sauvignon blanc. For selected clones were compared phenological phases, uvological characteristics, analysis of grape must, wine analysis and sensory evaluation. The experiment was carried out in the vineyards of the company Ampelos a.s. It was observed eight clones of variety Sauvignon Blanc. It was observed phenological phases in the same conditions of given clones. It was then determined uvological characteristics of bunch of grapes which was aimed on the average weight of bunch of grapes, the average weight of berries, the average weight of berry, the average weight of stem, the average number of berries and the average size of bunch of grapes (length x width). In the grape must were measured the analytical values, such as the sugar content, the amount of titratable acid, pH, the assimilable nitrogen content. From the results, it was clear that clones from Czech selection are much better adapted to the Czech climatic conditions. It was also observed that not all clones from Czech selection achieved better results than clones from abroad. This was confirmed in the case of clone 29/68 which has got the worst results from the all observed clones. As an ideal option for producing high quality wines is a planting composed from multiple clones with different characteristics.

Pěstování a vlastnosti plodů rakytníku řešetlákového
Stuchlíková, Veronika
This thesis presents an overview of the history, occurrence and claims for environmental and agricultural technologies in growing the type and contains of fruit substances. In addition, the literature review describes the laborious harvest, many species, but also a wide range of options for how to use the buckthorn. A part of the study was to compare returns from species (´Hergo´, ´Vitamínová´, ´Buchlovický´, ´Leicora´) and on this basis recommend the species, which are suitable for cultivation in Czech republic. Moreover external parameters were compared and the substances contained in the fruits of different species. This made it possible to compare the species with the highest and lowest solid, refractive solids, vitamin C, carotenoids and simultaneously fruits with the largest and smallest length, width and also with highest and lowest weight.

Obsahové složení vybraných genotypů Actinidia arguta z různých lokalit ČR
Vejražka, Martin
The aim of the thesis was to compile a review of literature on the species Actinidia arguta and other main representatives of this genus (Actinidia deliciosa and Actinidia kolomikta), together with a description of the genus Actinidia. For selected genotypes to determine the content of the substance in the flesh and skins of species Actinidia arguta (varieties 'Issai', 'Ananasnaya' a seedling 1) and Actinidia deliciosa (varieties 'Hayward' and 'Sorelli'). Mentioned representatives described their origin and distribution, botanical characteristics, varietal characteristics, their habitat requirements, methods of reproduction and substances contained in fruits. The experimental part deals with the determination of ascorbic acid, all acids, antioxidants, soluble solids content and the determined methods FRAP and DPPH. The results of individual measurements were processed and statistically analyzed. The values obtained were sorted into tables and graphs, and subsequently described in the text part.

Méně známá zelenina - Cynara scolymus L.
Sedláčková, Martina
The main target of this bachelor work is describe cultivation technology, significant content substances, present range of varieties and show possibilities of cultivation in Czech republic. Cynara scolymus L., Globe Artichoke, is a perennial thermophilic vegetable belonging to Asteraceae or Compositae family. Its stem grows to a height of two meters and at its end flower buds are created, which have a variety of colours after flowering. For consumers' purposes they are harvested unopened, the other parts of the plant are also used. Its extensive healing effects have been helping human bodies since the ancient times. The origin of an artichoke can be found in the Mediterranean, from where it has gradually spread throughout the world. In the Czech Republic, artichokes aren't grown mainly due to unfavourable climate. Their cultivation requires a lot of care, they like deep, fertile, humus-rich soils. That's why the Europe's biggest growers are Italy, Spain, France and Greece. Currently there are registered many different varieties of artichoke, which differ in size and shape of the flower buds, spinose of bracts or flower colour. Based on the findings of the experiment can be stated, that under the conditions of the Czech Republic, the most appropriate location was south Moravia. Suitable varieties could be ´Green Globe´ and ´Spinoso Sardo´. For verification would be good to continue in the experiment.
