Notice of termination due to organizational reasons under Section 52(a) through (c) of the Labour Code
Zábranský, Petr ; Pichrt, Jan (advisor) ; Drápal, Ljubomír (referee)
The aim of this thesis is to deal with the notice of termination due to organizational reasons under Section 52(a) through (c) of the Labour code. The topic of the thesis does not consist only in organizational changes and a notice of termination linked to them, its purpose is to describe the whole picture of the process of giving the notice to an employee and details which an employer must remember to keep the notice valid. The thesis is composed of ten chapters not counting the Introduction describing the motive for choosing the topic of the thesis and the aims of the thesis and the Conclusion containing the brief evaluation of the legal regulation. Chapter One deals with the labour-law relations, their concept and the distinctions between the individual labour-law relations and the collective labour-law relations. Chapter Two is concerned with the termination of employment in general and describes the division of the ways in which employment may be terminated, i.e. legal acts, legal events or authoritative decisions. Chapter Three elaborates the issues common to all reasons for the notice, which means that the attention is paid to these reasons, the written form of notice, delivering and the withdrawal of the notice and the participation of trade unions in a termination of employment. Special attention...

Analysis of water requirements of the field crops in areas with frequent occurrence of drought.
Zábranský, Petr ; Soukup, Josef (advisor) ; Jan, Jan (referee)
Summary
Water resources are an important part of ecosystems. In the water balance of the landscape, the variability of climate, soil factors, as well as high diversity of vegetation play an important role. Evapotranspiration represents a major passive component in the water balance of the basin. Unlike forests, where the water balance is particularly predictable due to the long-term development of the stands, regular crop rotation in agricultural systems and agricultural practices may cause rapid changes in water balance during much shorter time. It may sometimes result in irreversible changes in ecosystems with impact on landscape biodiversity. An understanding of the limiting environmental factors and exact determination of the water demands of plants makepossible not only an improvement of yield parameters, but it is also condition for understanding of the agroecosystems sustainability in the cultural landscape.
Field measurements of actual evapotranspiration were carried out in the period 2007 to 2015 in Velvary (Budihostice) in the Central Bohemia region, 210 m above sea level in the rain shadow area around Slaný territory. In terms of the average annual water balance (CHMI, 2014), the locality is regarded as the area with the difference between the average annual precipitation and annual potential evapotranspiration totals in amount of -200 mm, so the potential evapotranspiration slightly exceeds precipitation. Field measurements were conducted on commonly managed areas with a minimum size of the experimental plots of 1 ha.
The measurements confirmed differences between the crop water demands during the growing season. Different values of the actual evapotranspiration as well as the Bowen ratio values were estimated for the observed crops depending on the growth stage of crops. The lowest values of actual evapotranspiration were detected for Zea mays and Sorghum bicolor. Higher water demands were shown by Triticum aestivum and Hordeum vulgare. On the contrary, the highest values of actual evapotranspiration were found in stands of Beta vulgaris and Medicago sativa. According to the values obtained for crop coefficients (Kc), the crops of Z. mays, S. bicolor and T. aestivum had about a quarter lower values of Kc compared with M. sativa and B. vulgaris crops in the main growing season. In this work, the daily values of Kc, which are the basic characteristics of moisture requirements for individual crop were determined and can be used modelling of hydrological processes in agro-phytocoenoses. The evaluation of moisture requirement of crops by the water flow in plants (determined by the sap flow method) showed the expected differences between S. bicolor and Z. mays plants. Water use efficiency (WUE) was significantly higher in plants of C4 type (Z. mays and S. bicolor) compared with the rest of observed plants of C3 type (T. aestivum and H. vulgare).

The influence of the number of plants on the yield of winter wheat in the context of precision seeding technologies
Paclt, Ladislav ; Brant, Václav (advisor) ; Zábranský, Petr (referee)
Winter wheat (Triticum aestivum L.) is the most commonly grown cereal in the Czech Republic. The sowing area covers about 795 000 hectares. Quality seed is a good basis for the formation of stand structure during development, which is reflected in the yield and quality of production. The structure of the stand is shaped primarily by the number of plants per unit area, thereby the amount of seed rate. In traditional agricultural practice, the amount of seed rate is determined mainly by sowing date and agricultural production area. It is used convertion MKZ to weight in kg. Required quantity of seed is therefore given in kg and not in seed number. Commonly used seeding-machines moreover, are not able to precisely follow the seed sown.
The aim of this study was based on field experiments to assess the effect of different seeding rates in precision sowing on wheat yield. It is known that wheat plants have exceptional compensation capability, which consists mainly in tillering. When precise positioning of seeds per unit area, which maximally eliminates competition between plants, therefore, even in reduced seed rate should not shown to decrease yield. It was also evaluated the effect of the application of fertilizer during sowing into the zone of plant roots.
Field experiments were carried out in the years 2014/2015 in the locality Budihostice (Central Bohemia), GPS coordinates 50 ° 17'48.664 "N, 14 ° 14'36.130" E. For seeding carried out 3. 10. 2014 was used test modular drill Farmet with width of 1.5 m and with the use of precision seeding. The zonal application to a depth of 85 and 180 mm at seeding was used NPK fertilizer (15/15/15) in a uniform dose of 80 kg/ha. Seed rate in the experimental plots ranged from 200 to 350 grains per m2. Control variant representing conventionally planting was established with a seed rate of 450 grains per m2. Total was based six variants without fertilization, six variants with the location of the fertilizer to a depth loosening of 85 and 180 mm and the control variant. Harvest was 30. 7. 2015.
Differences in the number of plants are primarily reflected in the number of ears on a single plant. This factor was the most important yield-forming element. Lower yield compared with the control variant, which achieved yield 9,509 t/ha, was set on plots with the number of plants under 200 pieces per m2. In areas with a number of plants more than 200 pieces per m2 was beyond one variant set higher yield. Variants with the number of plants more than 230 pieces per m2 and fertilization achieved a higher yield than areas without fertilization. These differences were not statistically significant. Influence of zonal fertilization was not surely proved.
The experiments have shown that reducing the number of plants per unit area may be due stand compensation capability provide similar yields as conventional variant.
