| Abstract | ||||
| The future increase in water demands with the required quantities and qualities is a serious challenge in the Kingdom. Therefore, improving the irrigation network is an essential goal for water conservation under the local conditions nowadays. The Hassa Irrigation and Drainage Authority (HIDA) is one of the largest agricultural projects in the Kingdom. It covers about 8000 ha. This project started about thirty years ago. Since that time the water was distributed to the farmers by siphoning the water from the field canal to the farm with the flood irrigation as the most method adopted. The consequence of that was unwise use of water. The objectives of this research work are: to evaluate the bubbler irrigation and the traditional trickle irrigation system to be an alternative to the flood irrigation especially under palm trees, and to evaluate the moisture distributions under systems currently used. To achieve these objectives a number of filed studies were conducted in typical farms in Al-Hassa Irrigation and Drainage Scheme, to evaluate irrigation efficiency and to determine the effect of irrigation systems and watering regimes on date palm production. Data indicated that reproductive growth of date palms were significantly affected by irrigation systems (furrow, bubbler and drip irrigation). Drip irrigation significantly increased yield, while no response was obtained under the three irrigation regimes during the study. Moreover, the data indicated that date palm water requirement in a loamy sand soil in Al-Hassa, Saudi Arabia is 1013.4, 1170.0 and 1407.0 m3/palm/year for drip, bubbler and furrow irrigation systems respectively | ||||
