Qatar is a country with no surface water supplies while the groundwater is saline and unusable for many crops. However, there is ample supply of seawater, treated wastewater and industrial water. In the present study, four types of irrigation water: groundwater (GW) (EC ≈ 2.00 dSm-1), treated wastewater, diluted seawater of electrical conductivity (EC) ≈ 10 dSm-1 and diluted seawater of EC ≈ 15 dSm-1 were applied to mature date palm trees for two years (2012 & 2013) and their effects on yield, fruit quality and soil characteristics including heavy metals were assessed. Experimental design was split plot with three replications. Results indicated that irrigation with treated wastewater affected neither the date palm yields and fruit quality nor the accumulation of minerals and heavy metals in comparison with groundwater. Hence, it could be an alternative source of irrigation. Diluted seawater either of 10 or 15 dSm-1 affected the date palm yields significantly (28 and 45 % decrease, respectively) and salinized the soil indicating that further dilutions will be required to bring seawater under safer usage. However, it is possible to use this water when diluted to a proper ratio of seawater and groundwater.
