摘要

We investigated the influence of mowing on the development of three grassland types in a mountainous area of the Slovakia: Treatment 1 was de-intensified permanent grassland, Treatment 2 grassland abandoned for approximately 10 years, and Treatment 3the same grassland but mowed grassland once a year, Treatment 4 weedy grassland caused by over-fertilisation, and Treatment 5 the same sward, but mowed once a year. Despite the differences in soil characteristics after two years of exploitation, a (bothqualitative and quantitative) convergence in botanical composition occurred. Logically, a divergence was detected between managed and non-managed treatments of abandoned and weedy grassland. The abandoned grassland was distinguished by higher dynamics than the weedy one in divergence. During the two years of the investigation, mowing decreased the dry matter production of the abandoned grassland from 4.61 Mg ha~(-1) to 2.30 Mg ha~(-1) in the abandoned grassland and from 5.53 Mg ha~(-1) to 3.83 Mg ha~(-1) in the weedy grassland.
