Therefore an experiment was carried out under field conditions, to investigate the effect of seven levels of salinity as: Karun river water with EC of 1.09, distilled water (0.01) and irrigation with hand made salinity of 3, 6, 9, 12 and 15 dS/m on the growth and development of three types of lawn namely: Lolium perenne L. cultivar Barball, Festuca arundinacea cultivar Kentaky-31-C and Cynodon dactylon cultivar Primo in the form of a 7×3 factorial with a completely randomized design in 3 replication. A number of leaves on the main shoot and tiller, fresh and dry weight of leaves, leaf area and a number of tiller per plant were recorded. According to the results, it was revealed that the effect of salinity, Genus and interaction were significant (P M3 ER -
