In the present study changes in the sod-formation of 8 lawn grass mixtures during four consecutive years of their usage were presented. Evaluation o f sod fonnation by the mixtures was conducted once a month applying a scalę from 1 to 9 (1 - an unfavourable feature, 9 - a highly desirable feature). Twenty-three to twenty-six cuts at a height of 4 cm were carried out during vegetation periods in the years of full utilisation. The present studies showed that the lawn grass mixtures studied varied in their sodding evaluation both in the individual years and on the observation dates during vegetation. In the first year of full utilisation, the foreign mixtures showed a more uniform sod formation and the grades given for their sodding ability were higher and less differentiated (6.7-9.0) than those of the Polish mixtures (4.0-9.0). W hereas in the following years of full utilisation, the Polish mixtures were characterised by a decidedly better and more uniform sod formation than the foreign mixtures, especially in the forth year. The best sod-formation on all observation dates (grades from 5.8 to 9.0) was observed in the case of the "Sport” mixtnres (Institute of Plant Breeding and Acclimatization in Radzików) and the ”Sport” (Agricultural University of Lublin).
