This greenhouse study evaluated the effect of the soil amendments, such as sand, Clinoptilolite Zeolite (CZ) and moler (calcined clay) on the germination and growth of two cool season turf grass species namely Lolium perenne and Festuca rubra. The germination was significantly better with the application of clinoptilolite than moler for both the turf grass species. Although, the addition of sand did not affect the germination rate of any specie, but the fresh and dry weight of turf grass species decreased with the increasing proportion of sand in the growing media (p<0.001). Overall, the addition of moler to the growing mixture provided better growth for both the turf grass species. Further research is required for detailed investigation on the physical and chemical role of different soil amendments in the growing mixture to obtain normal plant establishment in landscape and play grounds under arid climatic conditions.
