Analysis of selected commodities from investor's point of view
Škultéty, Daniel ; Trešl, Jiří (advisor) ; Václavík, Tomáš (referee)
The purpose of this thesis is to analyze investment options into wheat, corn and rice futures throughout different time horizons. Mostly we use daily closing prices for the last fifteen years. General knowledge of the field in context of nowadays is required to perform such an analysis. To achieve our goals we use technical analysis, time series analysis and we discuss the fundaments of price movements. Contribution of this thesis can be summed as presenting the basic tools of technical analysis in real world, presenting the fundamentals of price movements in one place and practical application of time series analysis on futures prices. By doing so we can confirm that random walk thesis is not unsubstantial but cannot be generalized for all instruments and periods of capital market.

Utilization of Zea mays L. for energetic effects
RATAJ, David
This bachelor thesis deals with the types of energy use of flint corn (Zea mays). It compares the suitability of hybrid maize lines. The thesis is to summarize and compare the literature data on other types of energy crops and compares them suitable for cultivation for energy recovery on the basis of some production capacity and energy parameters (dry matter yield, energy recovery, combustion heat and humidity).

Different proces of utilization of silage hybrids of corn
VOJTOVÁ, Iva
The work is devoted to various related uses of corn silage hybrids. The aim was to describe and evaluate the effective yield potentials, processing Technology and utilization of maize hybrids for different manufacturing and industrial purposes. The issue that I stated in the individual chapters and opinions from experts. The thesis was to summarize the literature data on selected types of maize cultivation in the agricultural suitability of the producing regions and how their use. I pay attention and corn hybrids that are applicable or appropriate Fodder utilization for energy purposes and are thus suitable substrate for biogas plants.

Hydrolysis of corn silage
MÍKA, Václav
Aim work is compare yield GE at acid, alkalic and enzymatic hydrolysis cellulose phytomass at different acidity (H2SO4, 3, 6, 9 and 12%), fundamentals (NaOH, 3, 6, 9 and 12%) and while using different enzymatic preparations (6 preparations to hydrolysis celluloses and hemicelluloses). Further is assessed positive influence compressive extrusion (0,3MPa and 1MPa).

Study of selected factors influencing maize for silage agronomic attributes
KADOUN, Lukáš
In the years of 2009 and 2010, an observation of chosen quantitative and qualitative measures of several hybrids of corn took place at PS Humpolec and ZD Hosín. Quantitative measures were evaluated based on dissection of individual plants, qualitative measures then through common laboratory methods. In the field experiments at PS Humpolec, an observation of the seeding quantity and nitrogen load took place. The seeding quantity influenced with very high size of effect all agronomical and seed figures, except for the number of rows in the cob, where only high size of effect was observed. The quantity of 85 thousand seeds per hectare seems to be optimal. The nitrogen load influenced with very high size of effect the weight of the cob, with high size of effect the number of cobs and the weight of grains in the cob. Other measures were not affected. The year influenced with very high size of effect the length of the plant, the number of leaves, the weight of the cob; with high size of effect the height of the first cob on the plant and with considerable size of effect the number of cobs on the plant and the length of the cobs. Other observed measures were not affected by the year. Optimal nitrogen load that can be recommended is 110 kilograms per hectare. The best digestibility was noted with 100 thousand seeds per hectare and 110 Kg of nitrogen per hectare, or with 70 thousand seeds per hectare with no nitrogen. In the operational and half-operational experiments at ZD Hosín, differences between chosen hybrids were observed. Based on the results, the best one that can be recommended for these environmental conditions is Karacho, with FAO 260. Hybrid Karacho achieved the highest yield of matter in both years and in the year of 2010 it also achieved the best digestibility.

Maize Growing for Energy Generating Purposes
NAVRÁTIL, Martin
In experiment we grown two maize hybrids for energy purpose. Growth was established as small plats. At maize growth main comparable datas were yield and content of dry mass. From outgrowth was selected maize hybrid with bigger yield and better biomass for next energy processing.

Production capacity and quality of silage corn silage hybrid selection of appropriate
SMAŽÍK, Jaroslav
The aim of this study was chosen for the field of observation should be hybrids of maize (Zea mays L.) for silage purposes from a wider set of hybrid genotypes. To evaluate the vegetation was established as a pilot experiment. Of this group were then selected 14 genotypes, which would satisfy most practical requirements. During the vegetation was monitored by formation of quantitative indicators required for silage maize hybrids. Before harvesting of collection of plants chosen for individual analysis of quantitative indicators, while processing the silage mass in laboratory conditions to evaluate selected quality indicators. When harvesting was imposed on the total yield of green and dry matter, dry matter content and proportion of buds on the plant.

COMPARISON OF GENETICEALY MODIFIED AND NON-MODIFIED CORN
BEZUNK, František
This thesis provides a general view of Bt-corn and the growing of this genetically modified plant in the Czech Republic. It comprises of two main parts, a theoretical and a practical one. The theoretical part deals with Bt-corn growing by agricultural companies and research institutes in the Czech Republic. The practical part provides a direct comparison of genetically modified and genetically unmodified corn. The DKC 3511 and DKC 4442 YG hybrids were selected as subjects of this comparison. The key aspects of the comparison are the outcrop and the extent of infestation of corncrops with fungic pathogens. Based on the results gathered in the practical and theoretical part of the thesis, pros and cons of Bt-corn growing in the Czech Republic will be assessed.

Production capability and growing specialities of selected energy plants
DVOŘÁK, Adam
Agriculture started the new way, instead of the food crops is icreased growing of energy crops. Thesis {\clqq}Production potencial and specificity of energy plant growing`` deals with evaluation of suitability of selected energy crops in field trials and theire needs of soil, clima and agrotechnology. The growth ability, health were evaluated during vegetation period and production potencial in harvest time in choosed group of energy crops. The thesis content also the seed quality, field germination and initial growth evaluated in conditions of anthropogenic soils.
