Stated that our country will be negatively affected by climate changes that will occur due to global warming, especially the decrease in water resources, the increase in the need for quality water, drought and desertification and the ecological deterioration associated with these. It is expected that these will gradually increase the irrigation salinity levels water used in crop production. In this context, knowing and managing the salinity tolerance of grass species and varieties frequently used in lawn areas is of great importance. Festuca arundinacea L. (Tall Fescue) is a grass species that is successfully used in green area establishments both in the Mediterranean Region and throughout our country and can create a quality grass cover. The aim of this study was to measure the responses of tall fescue grass cultivars to saline irrigation water and to investigate the effect of microbial fertilization in alleviating salinity stress. In the study, seeds of new fescue-like cultivars “Meister, Eyecandy and Tomcat” were planted in pots with microbial fertilizer application (0-107 CFU/g) in Akdeniz University Faculty of Agriculture Greenhouses. Irrigation was carried out at 4 different saline irrigation water levels, which were applied at 0-5-15 and 30 dS/m levels. The experiment, was carried out with the non-salty class soil, was planned as a randomized plots trial design with three replications and a total of 72 pots were studied. Grass varieties were evaluated in leaf burn rate, grass quality, shoot and root dry weight, amount of cutting products and SPAD readings. As a result, it was observed that tall fescue varieties were affected by saline irrigation water applications, but microbial fertilization applications did not have a positive/negative effect on salinity stress. Differences in damages related to salinity applications were determined based on varieties, but microbial fertilization was not enough to correct this deformation. A healing effect is definitely expected in studies where the dose of microbial fertilizer is increased and the salinity level is slightly reduced.
