The influence of water regime and management on the productive capacity of grassland
 JANDA, Jiří
The first part of the thesis is devoted to the distribution, importance of permanent grasslands, proper management of grasslands and maintenance of optimal water regime. Water is essential for photosynthesis and plant growth and therefore its availability affects the quantity and quality of biomass produced. The literature on water regime such as rainfall, soil permeability, ground water availability and its effect on grassland production capacity is reviewed. Management techniques such as fertilization and tillage that can help maintain a suitable water and nutrient regi-me for the grassland are also described. In the second and third parts of the thesis, the results of investigating grazed and mown grassland under different water regime and animal load are presented. Furthermore, the climatic conditions of the site are described. The botanical condition of the grassland is elaborated. The influence of the load and water regime on the condition and productivity of the grassland under study is eva-luated. As the water regime increased, the cover of valuable grasses and clovers decreased and the proportion of reticulate and sedge species increased. Measures (fertilization and amendments) were proposed to improve the species composition of the vegetation.
