Two field experiments were conducted at Suez Governorate, Agrod, Command of the Third Field Army, Arab Republic of Egypt, during the two successive seasons of 2016 and 2017, to study the impact of irrigation water type treatments i.e., potable water, reclaimed water, potable water + reclaimed water and potable water + untreated wastewater on growth and chemical composition of seashore paspalum turf grasses. The results indicated that irrigation water type treatments have significant effects on vegetative growth and chemical constituents in cuts of seashore paspalum turf grasses, in m turf grasses, in the two seasons. The maximum means of these characters are recorded with potable water, followed by seashore paspalum turf grasses irrigated with potable water + reclaimed water without significant difference in grass density%, it was found many  measurements such as fresh weight, pigment and mineral content obtained the second position, while the lowest values were recorded as a result of irrigation with potable water + untreated wastewater in both seasons. Therefore, we recommend using potable water + reclaimed water, as this works to provide half the amount of potable irrigation water.
