The total weight of dry root biomass occurring in the depth of 200 mm and stratification of root biomass of turf cultivars of grasses (Poa pratensis, Agrostis tenuis, Deschampsia caespitosa, Festuca arundinacea) were evaluated in polyfactorial field trials within the period of 1997-1999. In all experimental years, Poa pratensis produced the highest amounts of root biomass (1333.50 g/square m) while Agrostis tenuis the lowest ones (906.96 g/ square m). The following descending sequence in production of total dry root biomass was found out after a comparison of some turf grass species: Poa pratensis, Deschampsia caespitosa, Festuca arundinacea and Agrostis tenuis. Using variance analysis and Tukey`s test for a statistic evaluation of obtained results a significant difference (P = 95 %) was found out between the total weights of root biomass of Poa pratensis and Agrostis tenuis. After spring and autumn sampling, the weight of root biomass was significantly (P = 99.9 %) different in all turf cultivars of grasses.
