Water resources are limited in arid and semi-arid regions. Therefore, there is a need to useeffluent and low-quality water sources [such as treated wastewater (TW)] for irrigation ofturf grass and landscapes. Application of TW changes the characteristics of soils, therefore,special management is required to obtain high quality turfgrass by such an irrigation, andits effects on soil characteristics and plants should be evaluated. In this research, the effectsof advanced treated wastewater of Shahinshahr Wastewater Treatment Plant was studied onfive varieties of Zoysiagrass, as well as its effects on soil, for a period of 10 months.Stolens of Zoysiagrass were planted in plastic pots containing sandy loam, loam or clayloam in August 2004. The pots were irrigated with municipal water until establishment.Thereafter, water requirement of each pot was calculated based on weighing the pots toreplenish the consumed or evaporated soil moisture. Irrigation treatments werecombinations of different percentages of water and TW (100% water, 75% water and 25%TW, 50% water and 50% TW and finally 100% TW). Statistical design was, completelyrandom design with factorial arrangement, having three factors: percentage of mixture ofwater and TW as the main factor, soil texture as sub-factor and turfgrass variety as the subsubfactor. The results indicated that using TW for irrigating turfgarss improved its color,and turf irrigation with mixture of 75% TW and 25% water had the best color (scale 5 outof 9). The Zoysia matrella varieties had better color than Zoysia japonica varieties. Thebest color (5.73) belong to DALZM3 variety, irrigated with TW. The best turfgrass colorwas seen in sandy loam (5.07) using 75% TW and 25% water, in loamy soil (5.06) using100% TW, and in clay loam soil (5.17) using 100% TW. Using TW increased yield per potand turfgrass height. Maximum height (9.08 cm) was obtained by using the mixture of 75%TW and 25% water, and maximum yield (10.07 g dry matter per pot) was obtained inirrigation with 100% TW. The turfgrass varieties had higher yield (4.55 g per pot) in loamysoil than sandy loam (3.48) or clay loam (3.59). But, plant height was not affected by soiltexture. Irrigation of turfgrass with different percent of TW changed soil characteristicssignificantly. Using TW increased N, organic matter, P, Na, and EC of soil significantly ascompared to water, while K, Ca, pH, Mg, Zn and Pb was not affected. Soil Fe was higher inwater treatments as compared to TW treatments. Chemical analysis of turf grasses showedthat N, K, Ni and Co absorption increased by increasing TW percent. Absorption of Fe, Cdand Zn was not affected. Absorption of Pb was decreased, but this decrease was notsignificant between 100% TW and combination of 50% TW and 50% water treatments.Soil texture was important in absorping heavy metals, such that Cd, Co and Ni absorptionwas maximum in sandy loam and minimum in loam. Absorption of Fe was not affected bysoil texture. The over
