Response of Four Warm-Season Grasses to Saline Irrigation Water Under Arid Climate
S.F. Alshammary, G. Hussain and Y.L. Qian

Abstract:
A 2 year field experiment was conducted to evaluate the growth response, proline and mineral content of four warm-season turfgrasses to saline water irrigation. Four salinity treatments were imposed on sandy soil by irrigation with waters at 2.0, 6.25, 12.5 and 18.8 dS m-1. The local bermudagrass, Tifgreen bermudagrass, Nagisa zoysiagrass and saltgrass experienced a 25% shoot growth reduction at 7.9, 20.5, 10.2 and 26.0 dS m-1, respectively. Although shoot Na+ and Cl contents increased linearly with increasing salinity for all species, the extent of increase ranked as: local bermudagrass > Nagisa > Tifgreen > Saltgrass. Sodium and Cl exclusion likely contributed to the superior salinity tolerance of saltgrass and Tifgreen. The experiment demonstrated that at 2.5 dS m-1 irrigation water salinity, Tifgreen, local bermudagrass and Nagisa all performed very well in Saudi Arabia. At 6.25 to 12.5 dS m-1 salinity, Tifgreen exhibited better turf quality than local bermudagrass and Nagisa and saltgrass. However, at the highest salinity (18.8 dS m-1), only saltgrass and Tifgreen showed acceptable turf quality which was significantly higher than the local bermudagrass and Nagisa.
