Vliv agrotechniky na produkční charakteristiky a ekonomiku výroby silážní kukuřice
Bártů, Ondřej
The subject of this thesis was through a field experiment to compare the economics of different options silage maize. Comparisons were ways to stand establishment and variants of fertilization, the nitrogen dose was always the same. It analyzed the influence of fertilizer with the addition of sulfur on maize cultivation. When comparing the establishment of vegetation were evaluated influences on selected production characteristics of silage maize. It was evaluated price per sown hectare, more expensive option, seeding side dress treatment under the heel was implemented through agricultural services and cheaper alternative was seeding fertilizer under the heel of machines owned by the company. Fertilization formed the basis of all variants urea applied before seeding at 250 kg per hectare. In cases when fertilizer was applied directly to seed, it was also used urea. The rest to a total dose of 200 kg nitrogen per hectare was in both versions foundation used more fertilizers, which was urea, manure and aqueous solution of ammonium sulphate with urea (SAM). Even if fertilization effects were evaluated at selected production characteristics depending on the price.

Vliv stanoviště a agrotechniky na produkci fytomasy vybraného klonu topolu (Populus nigra L. X Populus maximowiczii Henry) pro energetické účely
NOVÁKOVÁ, Aneta
The thesis deals with theme of fast-growing species and with the impact of agricultural practices (like choice of location, care and possibility of fertilizers usage) which are the most important factors for successful cultivation of energy tree species. The introductory part of the thesis contains an explanation of the term biomass and its possible distribution by types and ways of obtaining the biomass. Following chapters deal with fast-growing tree species. The issues of cultivation are also described here in parts like basic characteristics, history of these energy species, legislative restrictions and procedure during founding of the plantation itself, selection and preparation of locality, the use of agricultural practices (cultivation, fertilization). The practical part deals with it´s own experiment with a clone of poplar J 105 (Populus nigra L. x Populus maximowiczii Henry). This clone of poplar was planted on four experimental plots. The growth depending on the conditions of habitat and selected agritechnical measures was observed in following years. There are descriptions of conditions on all localities, chosen ways of planting and aftercare about tree vegetation. Another experiment which contained adding different types of nitrogenous fertilizers was performed in the last period of observing. Results showed that the greatest impacts on the quality of the growth of fast-growing trees have properly chosen location and aftercare about tree vegetation, at least in the first vegetation period. Addition of fertilizer seemed as important only in case of planting on nutrient very poor sites.

Evaluation of genotypic response of winter wheat production interventions
Bláha, Tomáš ; Faměra, Oldřich (advisor) ; Pavel, Pavel (referee)
Sources used in this thesis concerns the cultivation, the development and the growth of wheat and its recommendation for agro-ecological conditions such as requirements for the crop, influence of the agricultural technologies to underground parts, fertilization of wheat, the optimum sowing date and sowing depth. In the next part of literature search there is an information about response of winter wheat for chemical protection including treatment morforegulator of growth. The end of literature search deals with the composition of wheat grain and its potential influence to quality.
The methodological part is devoted to independent description of characteristics of the varieties which are included in experiment. Data for evaluation are based on literature published by ÚKZÚZ. This part summarizes the equipment used for conducting an experiment. Equipment consists machinery and laboratory equipment.
The experiment was located at two places - in Úhřetice near to Chrudim and in Krukanice near to Plzeň. Both places are valuated in the essay - description of altitude, soil type etc.
Evaluated results of experiments are at the end. The conclusion of my thesis is that more comfortable climate for growing wheat is in Úhřetice - the average yield is for almost 20 % higher than in Krukanice. Other conclusion is about late sowing date which reduces yield and about increasing number of antifungal treatment increases the yield. Each of the varieties are valuated in the next part and the best treatment options for them are recommended. One fungicide treatment is proposed resistance to disease (Bohemia, Seladon), dual fungicide treatment is recommended for the rest of varieties. Field evaluation of disease shows that intensity of the treatment must respond to the current situation (according to the year).

Possiblities of winter barley cultivation in CZ
Turnovec, Tomáš ; Křováček, Jan (advisor) ; Vašák, Jan (referee)
Winter barely is after winter wheat and spring barley third most grown cereal in the Czech Republic, grain yield rank id in 2nd place after winter wheat. In the Czech Republic winter barley is mainly used for feed purposes. The forage quality is the varieties with larger grain at the level of feed spring barley varieties. In the winter barley crop rotation allows favorable distribution of labor peaks in both drilling and especially in the harvest, because of the early harvest is best previous crop for rape. Economic benefit earliness of harvest of winter barley is also reducing the cost of holding stocks from the previous harvest, because it provides the first harvest of grain intended for production of animal feed.
The theme of this Bachelor thesis is to verify the suitability of cultivation of hybrid winter barley in the Czech Republic. The aim was to confirm or refute the claim that hybrid barley gives a higher yield in comparison with the line varieties.
In 2014 was founded 15 reference experiments in the Czech Republic. The selected sites were located at different altitudes and different soil conditions. Any attempt from 15 locations was based on an even plot with a total size of at least 4 hectares. 4 were sown winter barley varieties - two hybrid varieties, two line varietes - each variety over one hectare. Individual varieties were clearly separated aisle at least one meter, in order to subsequently ensure accurate income assessment.
As a hybrid winter barley varieties were sown varieties Galation and Wootan. As a comparative linear varieties of winter barley varieties were used designated as L1 and L2.
Results:
Location height above sea level soil type yield at 14% moisture (t/ha)

The highest yield of hybrid winter barley was in the location Loštice with an altitude of 305 metres above sea level and loamy soil. Hybrid varieties are achieved the yield: Wootan - 12.02 t.ha-1, Galation - 11.32 t.ha -1. Along with three other locations, were even here the yield of hybrid varieties overcome by lines, Line 1 achieved the yield 12.28 t.ha-1 and Line 2 surpassed its yield of 11.46 t.ha-1 only hybrid variety Galation. The second highest yield was achieved in the location Kravaře with an altitude of 300 metres above sea level and loamy clay soil. Hybrid varieties in this area witj average yield 11,42 t.ha-1, surpassed the line varieties about 1,295 t.ha-1.
Although the vegetation year 2014/2015 was not in terms of climatic conditions ideal because of the widespread drought that has manifested itself in early 2015, hybrid winter barley amounted to an average 0.92 t.ha-1 a higher yield compared to a line varieties. The main reason, that hybrids are also better in stress conditions in the form of droughts, is their bigger and stronger construction and extensive root system that can draw moisture and nutrients from deeper soil horizon more efficiently than conventional line varieties. With regard to the quality, hybrid varieties in this respect are comparable to the lines.
In our experiments high yields was achieved. Yields exceeding more than 11 and somewhere even 12 tons per hectare can be considered as excellent.

Maize growing in the Czech Republic
HOVORKA, Jaroslav
This bachelor thesis deals with the cultivation and use of maize (Zea mays) in the Czech Republic over the past 24 years. The work is written like a literature review. The maize is irreplaceable crop in human nutrition and it is widely used for feeding, industrial use and for energy purposes. Thanks to wide range of hybrids the maize is grown in different climates, with the specific goal of growing and high yield potential. Maize is widely grown crop in our country. There have been changes in the cultivation and use of maize from 1990 to 2013. Thanks to these changes, the Czech Republic became an exporter of maize grain. From the collected data and information, it can be stated that sowing areas are growing. This fact contributed to the construction of agricultural biogas plants, because the maize is the major substrate. Agrotechnics of maize is continually developing and its changes lead to reduction in soil erosion and to higher returns. Other changes that have occurred in agrotechnics, sowing areas, yields and the reasons for those changes are solved in this work.
