英文摘要	A field experiment was conducted on date palm trees (Phoenix dactylifera 'Succary') cultivated on sandy loam soil from 2017 to 2018. This study investigated the effects of providing water of three different qualities, namely freshwater (FR) and two saline water sources: reclaimed wastewater (RW) and well-water (WE) applied through three irrigation levels representing 50% (I-50), 100% (I-100), and 150% (I-150) of crop evapotranspiration (ETc), on the soil water and salt distribution patterns, yield, water productivity (WP), and fruit quality of the ' Succary ' date palm. The electrical conductivity (ECw) of FR, RW, and WE were 0.18, 2.06, and 3.94 dS m(-1), respectively. Results showed that WE applied by the I-150 treatment had the highest soil water content, followed by RW used in the I-100 irrigation level and FR with I-50, whereas the soil salt content was high for WE applied in the I-50 level and low for FR applied by the I-150 treatment. Deficit irrigation (I-50) of date palms with either RW or WE reduced date yields on average 86 kg per tree, whereas the yield increased under over-irrigation (I-150) with FR to 123.25 kg per tree. High WP values were observed in the I-50 treatments with FR, RW, or WE (on average 1.82, 1.68, and 1.67 kg m(-3), respectively), whereas the I-150 treatment with each of the three water types showed the lowest WP values. Fruit weight and size were the lowest in the full irrigation (I-100) with WE, whereas the I-150 treatment with RW showed the highest values. There were no significant differences in either total soluble solids (TSS) or acidity values when the irrigation level decreased from 100% to 50% ETc. Compared with both I-50 and I-100 treatments, reduced values of both TSS and acidity were observed in the I-150 treatment when ECw decreased from 3.94 to 0.18 dS m(-1),. Fruit moisture content decreased with the application of saline irrigation water (i.e., RW or WE). Total sugar and non-reducing sugar contents in fruits were found to be decreased in the combination of RW and I-150, whereas the 50% ETc irrigation level caused an increment in both parameters. These results suggest that the application of deficit irrigation to date palm trees grown in arid regions, either with FR or without it, can sufficiently maximize WP and improve the quality of fruits but negatively affects yield, especially when saline water is applied. The use of saline water for irrigation may negatively affect plants because of salt accumulation in the soil in the long run.
