The aim of the study was estimation of some morphological and biological features and yielding of seven grass cultivars sown for fodder production on grassland. The objects of the study were cultivars of three low-growing grass species: Lolium perenne, Poa pratensis i Festuca rubra. The cultivars were evaluated in the next four years of utilization. Tillers density, growth rate of sward, earliness, yielding and yield structure of the first regrowth in pure stands and in two mixtures were evaluated. In the sowing year and in the third year of full utilization the underground biomass in the topsoil was also determined. The L. perenne cultivars were ranked, in terms of their earliness, in the following order: Naki (early), Diament and Gagat (mid-early), Bajka (late). It was found that L. perenne cv. Bajka was characterised by a greater tolerance to changing weather conditions (drought and frost) compared to other cultivars of that species. Among P. pratensis cvs., Eska-46 revealed more favorable features.
