Turfgrasses are essential natural element of any landscape, which play a dynamic role in redecoration of gardens, parks, golf course and play grounds. Cynodon dactylon L., cv. Tiffany is a warm season turfgrass having vibrant value and reputation because of its stunning appearance, hardy nature, soft carpet sensation, drought, salinity resistance quality, heavy traffic bearing and browning . In which Salinity is one of the major environmental factor which limits turf growth and quality because it reduces water availability for plant use. High salt levels hinder water absorption, inducing physiological drought in the plant. Scarcity of fresh water along with soil salinization has resulted in an increased need for screening of salt tolerant turfgrasses which have the ability to withstand against different salinity levels. Keeping in view, present research was laid at research area of horticulture department, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi 33.60000 N, 73.03330 E. The experiment was carried out to check growth response of warm season grass (Cynodon dactylon) to different salinity levels. The treatments thus formed were Control/ 0ppm; NaCl @1000ppm; NaCl @3000ppm; NaCl @5000ppm; NaCl @ 7000ppm. The qualitative and quantitative parameters were analyzed, results showed maximum quality and growth of turfgrass along with salt tolerance at NaCl @3000 ppm and minimum at NaCl @7000 ppm. Through these results it was concluded that the rate of growth was decreased in correspondence to increased salinity but plants were tolerable up to the certain level without any reduction in their growth.
