This thesis summarizes the results obtained from a study of long-term field trials with permanent grassland, which based on Faculty of Agriculture, University of South Bohemia in the České Budějovice between years 2010 - 2013. Permanent grasslands are managed in different ways (mowing, mulching, fallow) and the intensity of exploitation (harvested 1 - 3 times a year, fertilization). The work was focused on the evaluation of changes in growth composition, biomass production and dry matter content of hay variants. Also were evaluated biodiversityand grazing value of the crop stand. Before each harvest (mowing or mulching) was evaluated growth composition of experimental grasslands on an area of 20 m2. Plant species coverage of individual agro botanical groups was estimated by the reduced projective dominance (% D). Harvested biomass of grassland was considered and sample mown every variantof the experiment was dried (dry matter content). Species diversity was expressed as the number of species and species diversity was expressed in the form of Simpson's index. It was also calculated value describing the quality and productivity ofthe crop stand.
