The aim of this study was to estimate the level of annual and daily growth of lawn plant height of Kentucky bluegrass cultivars depending on the intensity of their utilization and to group bluegrass cultivars into slowly and quickly growing. The basis for the study was the results of cultivar tests conducted by COBORU in 1998-2004 at three Experimental Stations of Cultivar Testing – Lisewo (54°06’ N; 18°50’ E), Łopuszna (49°29’ N; 20°08’ E) and Pawłowice (50°28’ N; 18°29’ E). Two systems of utilization were applied: moderately intensive (Relaks) and extensive (Park). At extensive utilization, annual plant growth values of all the tested cultivars were smaller by 20-30 cm, and average daily growth values by 0.14 cm smaller than with their intensive utilization. The slowly growing cultivars were Alicia, America, Baron, Bartender, Broadway, Limousine, NIB398, Orfeo, RAH498, Samoa and Qantum Leap, and quickly growing – Gol, Mardona, Haga, Sobra and Evora. At the utilization system Relaks, daily growth values of slowly growing cultivars were on average by 25% smaller, and at the Park system, by 35% smaller than those of quickly growing cultivars.
