The present studies concerned 21 cultivars of 7 lawn grass species (Agrostis canina L., Agrostis capillaris L., Festuca heterophylla Lam., Festuca ovina L. sensu lato, Festuca rubra L. sensu lato, Lolium perenne L., Poa pratensis L.) and Festuca arundinacea Schreb. Two sowing dates were applied: spring and late summer. Six to ten cuttings were made during the vegetation periods in the years of full utilisation. The rate of re-growing after cutting was evaluated on the basis of plant height before each of the following cutting. All Poa pratensis cultivars and Agrostis genus species characterized by the slowest re-groving rate after cutting. Among the remaining cultivars Niko (Festuca ovina), Nimba (Festuca rubra), Sawa (Festuca heterophylla) and Stadion (Lolium perenne) showed slow rate of re-growth. Cultivars of studied species (except from cultivars of Agrostis genus) sown in the spring were higher before each cutting than those sown in late summer.
