Dry grassland restoration on a limestone quarry landfill using different sowing densities
 Strušková, Eliška ; Kuťáková, Eliška (advisor) ; Mudrák, Ondřej (referee)
Grassland restoration by sowing seeds of native species is one of the most commonly used methods of community restoration, especially in cases when conditions are not favourable for spontaneous succession, for example due to absence of a suitable seed source in the vicinity or introduction of unsuitable substrate. Although seeding is commonly used, there is still no consensus on what seeding densities are sufficient to restore the target community. The aim of this thesis is to assess the influence of seeding density on species composition of the restored xerotherm grassland on two different substrates in a limestone quarry in the Czech Karst during eight years from the beginning of the restoration. It also assesses the influence of the subsequent management of the site, specifically grazing. The results of this thesis show that the sowing density influences plant community composition and vegetation cover only in the first five to six years of the community development and only on the quarry substrate. On the ex-arable soil seeding density does not significantly affect the community composition. Plant community on this substrate is dominated by ruderal species. Grazing promotes vegetation development towards a community of dry grassland and suppresses non-target ruderal species. These findings can...

The technology of cultivation of spring barley (Hordeum vulgare L.) and its use
 KRUML, Martin
The aim of my thesis was to introduce you to using research to the cultivation of spring barley (Hordeum vulgare L.). Cultivation of barley, I mean everything from the biological characteristics through soil preparation to planting and harvesting. For this search, I used books by Czech authors who write on this subject, as I used articles of foreign authors writing about issues influence of fertilization on spring barley, and I took advantage of practical experience with the cultivation of spring barley agronomists working in the company ZKS AGRO Zahořany. I tried to encompass the whole issue of growing spring barley and all carefully recorded.

The Minimalization of the soil tillage in the higher spheres
 DOKULIL, Jan
The aim of the work was to monitor the yield elements and economics at indulgence of the winter barley and economics of the winter rape with usage of conservative technologies (shallow soil loosening, deeper soil loosening without reversion of the soil {--} only by the rape) in comparison with the conventional soil tillage (tillage). The yield elements by the winter barley were different in both years 2006 and 2007. In 2006 it was for the benefit of the tillage and in 2007 for the benefit of the shallow soil loosening. The number of growths was demonstrably higher at conventional soil tillage in spring and in autumn. The grain yield and the costs of herbicidal protection were observed. The highest yield at the winter rape was achieved by deeper soil loosening. The second place option was a variant of a tillage and the worst yield was found out in the shallow soil loosening. The final costs of the foundation of vegetation and herbicidal protection were lowest at the minimal soil tillage in all the options.
