Pulkrábek, Jan ; Přibil, Rudolf (advisor) ; Hovorka, Jan (referee)
With increasing frequency of problems caused by global climate change, the scientific community trying to find possible solutions to reduce greenhouse gas emissions into the atmosphere. One of the possible solutions of this problem is considered the system of separation, transportation and long-term storage of C02, called CCS - Carbon Capture and Storage. This work is a literature review issues of CCS in order to determine the possible use of CCS in the Czech republic. There is a basic system description of CCS, the possible environmental risks associated with it, and finall summarize of the prospects of deployment CCS technology in Czech republic.

Koukolíček, Jan ; Pulkrábek, Josef (advisor) ; Milan, Milan (referee)
The experiment which was done on the fields of Cooperative farm in Nečín should verify three soil conservation technologies with three most cultivated legumes in the Czech Republic. We tested deep cultivation, shallow tillage and no--tillage technology. And we used winter pea which was seeded in two terms in the autumn and in the spring. Spring pea, narrow- leafed lupin, white lupin and soya were seeded only in the spring term. We tested soil density and soil moisture with different soil conservation technologies. We observed vegetation stages and we made pre--harvest and post--harvest evaluation.

Establishment of corn crop stands by soil protection technology on land fealds withs slightly soil erosion condition
Herout, Marcel ; Pulkrábek, Josef (advisor)
The work is based on the needs of farmers who grow corn for cattle feed and biogas plant. For many farms corn is a strategic crop. But i tis also an erosion crop and therefore it is necessary to pay attention the erosion. The experiment is set in terms of ZD Krasna Hora nad Vltavou. The firm manages on mildly and severely threatened soil by erosion and there comes a potential problem with water soil erosion too. It is tested 3 soil conservation technologies with different spreads rows and different crop density. It is monitored the effectiveness of various anti-erosion technologies, stand density and row spacing. Measurement is managed by Research Institute of Soil and Water Conservation. The yield of individual parcels was evaluated. The biomass yield and grain were determined.

Production yield of sorghum grown for biogas production
Adamčík, Jiří ; Pulkrábek, Josef (advisor) ; Vladimír, Vladimír (referee)
Low temperature during germination is a major limiting factor affecting growth of sugar sorghum in the Czech Republic. The aim of the study was to determine the ability of stimulated seeds germinate in slightly adverse conditions (less optimal temperatures) and evaluate the impact of biologically active compounds to faster germination of sorghum seeds and next plant growth. Two sorghum seed lots were treated by auxinous preparations Lexin and M Sunagreen. Germination was tested in germination chamber at temperatures 12, 15, 18 and 21 °C in the dark for 14 days. The results confirm stimulation of sugar sorghum seeds and increase of the germination speed at lower temperatures. Top acting biologically active agent (for faster germination) was Lexin. This product has a significant impact on increasing of the seed vigour. In less favorable conditions (12 ° C) application of Lexin increase germination speed of sorghum seeds by a full five days. Shortening of mean germination time was detected after M-Sunagreen application too. 25 cm row spacing on sorghum sugar and 50 cm on the grain sorghum were the best in our experiments. We have found that fertilizer Urea Stabil before sowing at a dose of 80 kg N.ha1 and then the same dose fertilization in stage BBCH 35 is preferred.

Precision sowing and the establishment of grain crops
Brinar, Jan ; Pulkrábek, Josef (advisor) ; Koukolíček, Jan (referee)
The object of the study was to compare the classical method of planting (small-plot complete seeder) and precise seeding for a given distance (prototype seed sowing machine FARMET for sowing with fertilizer under the heel) for winter wheat. Chosen were various seeding rates for precision and classic sowing machine into the cereals. Tested were sowing rates from 1.0 to 4.5 MKS. The experiment was done in the period 2014,2015 at the research station CUA in Prague-Uhříněves. The chosen variety was forage winter wheat Penalty quality C from PROBIO of 2014. For the basis of the hypothesis was selected seed rate of 2.0 MKS in precision sowing against 3.5 MKS in a classical way of sowing. The goal was to determine whether the reduced seed rate during sowing precise manner provides the same yield as a recommended seed rate of a traditional methods of seeding. The forecrop was a spring barley. Soil was prepared using the minimize blade cultivator before sowing of the wheat. Some variants of the experiments were fertilized at planting to promote germination. These variants were fertilized with 150 kg N / ha freely to the soil before sowing or 150 kg N / ha under the heel when sowing fertilizer Nitrophoska perfect. Furthermore, all plots were fertilized with 140 kg N / ha in three divided doses in a LAD 27, without distinction. Dry summer in 2015 hadn´t a devastating effect on wheat and most variants of the experiment gave a very good yield. The assumption that there will be savings precision sowing seed while preserving the yield was confirmed. Additionally it was shown that precise sowing on average in all variants seeding rates, fertilized before sowing or not surpassed yields of classic seeder.

The new LPIS evidence and its link to subsidy programmes
Koniaríková, Kateřina ; Pulkrábek, Josef (advisor) ; Jiří, Jiří (referee)
The Czech Republic, as well as the other EU states, has commited to the setting of the system for the evidence of the agricultural used land. In 2014, there was a new modul LPIS (Land parcel identification system) established, which is being used as the information service for farmers. They can find here the needed datas about the utilized agricultural land, but this system is also used for the data control that are being set in the application form for the subsidies from Europien funds.
In my thesis I summarised concisely the development of the Common agicultural politics including the news for the following subsidy period. In the chapters I paid the attention to the Programme for the rural development and its new setting for the period 2014-2020. But primaly, I focused on the LPIS land evidence, the reason of its setting and on the benefits to the farmers and the governemt. There is also the special chapter about the changes in LPIS evidence after 2015. My intention is to show the users the news, which they can meet during their work with the land evidence and with the application forms for the subsidies.
The aim of this thesis is to evaluace the ability of the chosen agricultural subject to orientate and to work with the new version of LPIS evidence. I established the cooperation with the State Agricultural Intervention Fund to gain the practical information about the LPIS application. I also asked for the cooperation the agricultural subject Havlíčkova Borová, zemědělská a.s., that farms in the region Havlíčkův Brod. I asked them for the access to their LPIS datas. I also tried to evaluace the fact, how the subject is able to prepare the underlays and how the subject proceeds the United application form for the agricultural subsidies.
In the end of this thesis I summarised the statistics of the applied United application forms during 2015 in the region Havlíčkův Brod. I gained these datas from OPLŽ employees. This statistics contains the datas regarding the number of the agricultural subjects that managed to prepare the application form for the agricultural subsidies by themselves and also the information, how many subjects used the services of the agricultural consultants or the services of SZIF employees, Department of the LPIS and request receiving (OPŽL). There is also information being involved in this thesis, what measures the farmers applied for in the frame of subsidies.

Evaluating new aromatic hop genotypes
Henychová, Alena ; Pulkrábek, Josef (advisor) ; Jaroslav, Jaroslav (referee)
Hop growers request new cultivar should have qualitative parameters of Saaz semi-early red-bine hop with higher yield potential. Therefore currently, there are efforts to breed new aroma cultivars.
The aim of diploma thesis was to evaluate and choose new breeding aroma genotypes, which would show equal or better quality and quantity parameters than Saaz semi-early red-bine hop registered cultivar, based on production indicators, chemical and genetic analyses. Obtained data were evaluated by basic statistical characteristics, two-sided t-tests for independent selections and correlation analysis.
A yield is the most important quantitative parameter, which is mainly and significantly dependent on climatic conditions. All evaluated genotypes in diploma thesis have reached higher average yields than ŽPČ cultivar, except genotype 4799. Genotype 4801 reached the highest theoretical yield (2.2 tons of dry hops) in year 2014 and genotype 4975 (1.77 tons of dry hops) in year 2015 from achieved results.
A content of alpha bitter acids is the most important qualitative parameter. All aroma new breeding lines have shown parameters of fine aroma hops according to chemical analyses of hop resins. Aroma genotype 4975 showed the highest average contents of alpha and beta bitter acids, balanced ratio between alpha and beta bitter acids, the lowest contents of cohumulone and colupulone, and as well it kept a low or middle variability in all studied traits of chemical analyses of hop resins. A relative content of farnesene higher than 12% is a typical for aroma hop cultivars with ŽPČ cultivar origin. All evaluated genotypes achieved this criteria.
We evaluated the relationship to Saaz semi-early red-bine hop cultivar based on genetic analyses. Genotype 4799 has been genetically the closest to ŽPČ.
Brewed beers have been a same quality as beers from Saaz semi-early red-bine hop cultivar by sensory evaluation.
