Diverzita vegetace vybraných travních porostů v okolí Míchova (okr. Žďár nad Sázavou)

This work deals with plant diversity, forage productivity and forage quality in selected permanent grasslands near the village of Míchov (Žďár nad Sázavou district), which are used as hay meadows and pastures. The phytosociological descriptions were recorded on five different grasslands, the biomass was taken and weighed, and the forage value was calculated for each observed ground in four replicates. Biomass production was determined for both, fresh forage and dry matter. The creditworthy classes were used for the calculation of the forage quality of the grounds. The studied permanent grassland respond to the intensively cultivated meadows dominated by Dactylis glomerata, Festuca arundinacea, Phleum pratense and Trisetum flavescens, and legumes. The less productive meadows of Arrhenatherion and Calthion allances are rarer. The determined fresh production of forage ranged significantly between 5–21 t.ha-1. Production of dry matter ranged between 1.7–3.7 t.ha-1. The number of species in phytosociological plots was high diversed and appropriate for particular type of grassland, 28–50 species per 32 m2. The forage value of the ground (bonita) differed significantly between the parcels, the values were between 48.1–89.68 points
