Species diversity and botanical composition of permanent grassland as a response to different grazing management practices

Popis výsledku v původním jazyce

The eff ects of diff erent levels of grazing utilization (two, three and four grazing cycles per year) and mineral fertilization (nil-fertilization; N100P30K60) on the botanical composition of permanent grasslands were studied in the locality of Rapotín(Czech Republic, 332 m a.s.l.) from 2003?2010. The vegetation of the experimental pasture was classifi ed as Cynosurion. It was found that moderate treatment (three grazing cycles per year) without mineral fertilization showed the highest value of diversity index (DI = 6.08), and maximum dominance of legumes (Dmax = 9.1%), particularly Trifolium repens. The highest dominance of grasses (Dmax = 77.7%), mainly Dactylis glomerata and Elytrigia repens, was achieved with the fertilized treatment utilized intwo grazing cycles per year. Based on RDA results, tested management treatments explained 26% of species composition variability, where eff ect of number of grazing cycles per year was fi ve-times higher than eff ect of fertilization.
