nder hot and desert climate, efficient utilization of the
meager water resources is of vital importance. Date palm
trees (
Phoenix dactylifera
L.) play crucial role on food security
pertaining to its ability to withstand desert climatic conditions
and high soil salinity. Eighteen young date palm trees were
established for about four years in concrete lysimeters
equipped with access tubes for soil moisture monitoring
using a calibrated Diviner 2000 capacitance probe. Split plot
experiment with main plots as three irrigation water salinities:
medium (12-15 dS/m), high (18-20 dS/m) and control (dS/
m<1) under 5-ALA and no 5-ALA treatments as subplots. Data
collected included actual irrigation water applied (AW) mm
and calculated actual water used in evapotranspiration from
soil moisture depletion (ET) mm. Physiological water use
efficiency (PWUE) was obtained by dividing actual ET by AW
for 46 irrigation events that extended over 446 days during
2016-2017. Results showed that salinity has overriding and
significant effects on date palm ET and PWUE. 5-ALA and
salinity interaction was highly significant in increasing ET
under electrical conductivity (EC) <1 while actual date palm
ET was reduced under medium and high EC. The application
of 5-ALA under EC<1 dS/m resulted in 77% photosynthetic
water-use efficiency (PWUE) compared with 31-59% on various
combination of 5-ALA and medium and high salinity levels.
Various effects of 5-ALA and salinity interactions on flowering
and chlorophyll contents were also discussed. Such results
are encouraging for further investigations on different levels of
5-ALA applications and fruit quality and food safety.
