Pomocné látky ve vinohradnictví - přípravek Vitality komplex
Rozkydalová, Radka
The aim of the thesis was to study and investigate written literary sources about aid substances used in viniculture. The substance named Vitality complex was then used in trial for experimental part. The trial was set in vineyard located in Slovacká wine-making area in village Karlín and was performer on varieties: Riesling Weiss, Pinot Gris and André. Substance Vitality complex was applied by spraying onto the leaves using concertation and time interval following the recommendations from substance producer. Substance application was performed from April till August. Control grape picking was done during August and September and quantity and quality changes against a check sample were observed. Focused parameters were weight of grapes and weight of bunch of grapes, sugar content, acid content, power of Hydrogen (pH) and yeast assimilable nitrogen. This gathered data were then processed and compared with existing trial results where different supporting substances were used.

Vliv foliární výživy u révy vinné - přípravek Fertileader Vital
Franc, Jaroslav
The present bachelor thesis deals with the use of foliar nutrition Fertileader Vital. in the process of growing grapes. This foliar nutrition is supplied to the domestic market by company Timac Agro CZ Ltd., This article is one of the Fertileader product line, and is referred to by the manufacturer as a biostimulator. To verify its effectiveness, a field experiment on a test vineyard ,deployed in the wine region of Moravia, subregion Mikulovská, the Perná wine-growing village in the vineyard "U Mikuláška", was established. A total of 248 wine grapes, the Welsh Riesling, the planting age of more than 60 years, for the experiment were dedicated. The field experiment methodology was verified in the practice way. The field experiment confirmed the positive effect of the tested nutritional product, on the vitality and health status of grapevine shrubs. The impact on the quality of the stum has been confirmed partly, probably due to the extreme stressful climatic situation in year 2018.

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

Výživa révy vinné - srovnání účinnosti hnojiv řady VIVE
Jůva, Martin
This thesis discusses the use and effectiveness of fertilizers VIVE series of viticulture. For the experiment were selected white grape variety Chardonnay. This work includes four variants. Option 1 is the control and treatment without fertilizer. In Option 2 was used VIVE Super NPK fertilizer, in Option 3 it was fertilizer VIVE Super Ligno. In Option 4 was again used fertilizer VIVE Super NPK + wetting agent VIVE Wet and last option 5, it was fertilizer VIVE Ligno Super + wetting agent VIVE Wet. These variants were applied in the same terms and 28 days and 14 days before flowering. Then again 14 and 28 days after flowering. Comparison of all variants were performed on the base uvology and analytical values. Of uvology values measured weight of grapes from one bush, the weight of one grape, berry weight and 50 berries, and then even the weight of stem. The main indicators were selected analytical sugar content, acidity pH and assimilable nitrogen. Further analyzes were also performed sheets after the application of fertilizers. Results showed differences in nutrient content in the dry leaves between experimental and control variants fertilized variant. The best results in terms of nutrition were achieved in variants which used fertilizer VIVE Ligno Super Series. Compared with the control variant significantly increased the contents of macronutrients (+43,1%), secondary nutrients (78.4%) and micronutrients (+38.8%). It was demonstrated that the use of fertilizers to increase the yield of grapevine and reduced acidity. Achieving higher sugar after application of fertilizer series VIVE in this work confirmed, however, the yield increased. Preparations had a significant influence on the content of assimilable nitrogen, which is very important during fermentation must. Health status of grapes was good, which appeared in the analytical evaluation of pH, which is for all variants ranged from 3.16 to 3.21, but due to bad weather development was necessary to harvest crops early.

Listová výživa ve vinohradu
Kreisinger, Kateřina
The thesis describes testing of powder water-soluble fertilizer produced by Fosfa, a.s. company on Chardonnay variety grown on the Most-Čepirohy vineyard. The fertilizer was prepared in three variants as a pure fertilizer containing makroelements N, P, K, Mg and S and microelements Fe, Cu, Zn, B and Mo. Extracts of seaweed were added to the second variant, the third one contained a surface-active agent, and the fourth one contained all the additives. In the spring before the fertilizer was applied, soil analysis was performed. Altogether the fertilizer was applied on the leaves five times. During the softening of berries, leaves were removed for an analysis. The analysis focused on the fertilizer efficiency and its ability to penetrate the leaves. In the stage of full grapes' maturity, uvological characteristics were evaluated. Samples for the juice analysis were removed from the harvested grapes. The following analytical values were determined: content of titrationable acids, sugar content, pH and assimilable nitrogen content. Individual variants were compared with a control variant without foliar application. The variant with the water-soluble fertilizer and the surface-active agent was determined as the best one, because it showed the best results from the perspective of leave analysis, increased sugar content, reduction of acid content and increased content of assimilable nitrogen. There were no differences observed in the plant health conditions nor uvological characteristics of individual variants. No influence of the seaweed extract on the grape quality was observed. Grape quality was significantly influenced by above-the-average rainfall during maturing and the grapes were infected by Botrytis cinerea.

Listová výživa ve vinohradnictví
Doležal, Jan
The bachelor thesis deals with auxiliary preparations in viticulture. The thesis consists of two parts -- first is the theoretical part, describing fertilizers, auxiliary preparations and plat physiology. Following is the practical part, consisting of an experiment with auxiliary preparation Terra Sorb Foliar on vineyards in the 2012 season. The experiment was carried out on the vieyard called "U tří dubů" and includes 2 varieties of vine -- "Ryzlink Rýnský" and "Tramín Červený." Each variety of the experiment involves "Treated" part and "Untreated" part. The whole experiment had been evaluated fo qualitative parameters (i.e. sugar kontent, pH, acidity any Yeast assimilated nitrogen content). Additionaly there were more experiments mentioned in the thesis, that were done in 2013 season. The result is, that the auxiliary preparation Terra Sorb Foliar has influence to qualitative parameters, mainly sugar content. Furthermore it influences growth dynamics, which in an advantage mainly during handling stress.
