Trunk sap flow in date palms growing in the United Arab Emirates
Data are presented from a field experiment to determine the water use of mature date palms (Phoenix dactylifera 'Khalas') which is a common local cultivar grown commercially in the United Arab Emirates (UAE). The experiments were conducted at the International Centre for Biosaline Agriculture (ICBA), near Dubai. Tree water use was measured directly using the compensation heat-pulse method (CHPM) with 140-mm-long sensors placed into the tree trunks. Local weather data was used to calculate the daily potential evaporation rate (ETO), and derive an appropriate value for the crop factor, KC, for this cultivar. Information from these field experiments will be used to parameterize a decision support tool for irrigation allocation being developed for the Environment Agency - Abu Dhabi (EAD) to improve the management of groundwater usage for date palms.
