Abstract: This scientific work aims to contribute to the sustainable management of water resources in golf courses of arid and drought-prone regions of Mediterranean, through the evaluation of water demands, regarding to different ways of environmental and socio-economic development and water resources, and through examining the possibilities to reuse treated effluent as an alternative source for potable water. Its main objective is to reach the response of fairway turfgrass of golf courses to several levels of sprinkle irrigation water. Bermudagrass (Cynodon dactylon) was selected as the most common turfgrass used in the many golf courses of the Algarve (southern Portugal), where this water consumption is responsible, for the decreasing of the level of aquifers and of their salinity elevation. Sprinkle point source experimental design was used to simulate several water regimes, expressed by the crop coefficients. Irrigation water sources were well potable water and two trea!
ted wastewater origins. Standard crop coefficient Kc values were evaluated between 0.92 and 0.99, being non standard crop coefficient Ks values for good appearance (GA) of lawn grass, very similar and computed between 0.52 and 0.55. Thus, significant economy of water could be achieved, in golf courses, if Ks values are used related to GA, instead of the usual standard Kc. The yield of the three experimental lawns was determined for several values of the crop coefficient under non standard conditions, due to the management of the sprinkler point source experimental design Ka, between 0.2 and 1.6. On the other hand, it was shown that the quality of turfgrass was independent of salinity of irrigation water for levels of ECw lower than 2.1 dS m-1 to the studied turfgrass. As concluding remarks, as the principal objective is the quality of the turfgrass of the golf courses and not the yield, it was shown that it is possible to consider treated final effluents as an alternative d!
isposal to potable water, to be applied in golf courses. The applicati
on of wastewater in golf courses is important in terms of water and fertilization savings and represents a more correct environmental alternative to the dumping of this waste in the rivers, lakes and seaside, since all cares are taken.
