In order to study the irrigation system and investigate the water requirement of date palm (Halili cultivar) in Minab Agricultural Research Station, an experiment was conducted as split plot with three replications based on randomized complete blocks design. The first factor was the irrigation method in two levels (surface and drip) as main plot and the second factor was the depth of irrigation water in two levels (75 and 100 percent evaporation from class A pan) as sub-plot. Each experimental plot consisted of two six-year-old trees at a distance of eight by eight meters. The studied traits included yield, water productivity, total soluble sugar content, average fruit weight, meat to kernel ratio, dry matter percentage and total soluble solids content. The results showed that treatment with 75% drip irrigation with the highest mean of water productivity (0.89 kg/m3) of water consumed over four years and an average of 7036 m3 of water consumed per hectare per year according to the drought challenge in recent years has been consistent with agricultural goals and is recommended in the region. In addition to the superiority of water productivity and the lowest amount of water consumed, this treatment showed superiority in all qualitative traits, except of the average weight of fruits.
