The objective of the research project was to determine the predisposition of Festuca rubra cultivars to deposit mat on lawns in their first year after establishment. In a field experiment of randomised blocks (blocks of 1 m2 in three replications) carried out in the Brody Experimental Station, twenty cultivars of Red Fescue fertilised with the following two levels of NPK fertilisation (kg/ha): I - 60 : 20 : 40 and II - 120 : 40 : 80 were investigated. In order to evaluate the over ground part of turf in its 0-5 cm layer, its weight was determined. Later, this plant material was used to perform chemical analyses with the aim to determine lignin and cellulose concentrations and to calculate the ratio of these two compounds (L/C). The obtained results allowed to conclude in the first year of utilisation, the examined cultivars of Festuca rubra exhibited considerable variability of the weight of turf over ground part and its Chemical composition with regard to lignin and cellulose. The highest L/C ratio indicating the tendency of Red Fescue to deposit plant mat faster was observed in Barcrown, Adio and Smirna cultivars. Intensive mineral fertilisation resulted in the inerease of lignin concentration and L/C ratio in the examined cultivars of Festuca rubra.
