Changes in the cover value of grassland species over a four-year period were investigated in terms of light requirements for grassland species under different management regimes (mowing, mulching, meadow management, overgrazing). The highest cover values of light-demanding grassland plants (Trifolium sp., Achillea sp., Plantago sp.), which are ecologically and economically valuable and typical for extensive grassland with a soil condition of Solonyec, managed by the MATE Research Institute Karcag, were measured under mowing and meadow utilization. The lowest cover values of light-demanding butterfly-flowering species were found in treatments covered with leafy phytomass and overgrazed with sheep. In the overgrazing treatment, we observed invasive emergence of the light-hungry Hordeum murinum, a potential threat to sheep welfare.
