A study was made on date palm trees to investigate the effect of three subsurface drip irrigation systems on the yield and water requirements of date palms. Experiments were conducted in Alwatania Agricultural Project - Gassim (350 Km north west of Riyadh), on 50 mature palm trees (17 years old) of Helwa type with 10 meters spacings between rows and between trees, all treatments were fixed during experiment except the subsurface drip line type (T-Tape, Techline, Queen-Gill). Irrigation scheduling was made through a soil moisture sensing device to ensure enough soil water level in the soil.
