Abstract
Drip irrigation has become a well-established method for irrigating high-value
crops in regions, where water resources are scarce and/or expensive. In Saudi
Arabia, the use of drip has increased fivefold since the 1990s, and now due to the
rapid increase in the use for drip irrigation system in the fields and greenhouses
in recent years in most agricultural regions in the Kingdom has caused the
availability of many drip irrigation components and products in the local market
made by different manufacturers. These devices differ in their qualities and
standards. Hence, the field evaluation of drip irrigation systems in the fields and
its components (i.e. emitters) is essentially required for standing the efficiency
and performance of the system and these devices during irrigation.
This study was mainly focusing on evaluating 10 drip irrigation systems
under field operation located in different farms in Riydh region of Saudi Arabia.
Also, the study included a survey study for 50 drip irrigation systems distributed
on a number of farms in the most agricultural regions in Saudi Arabia using drip
irrigation systems. Results of field evaluation show that the irrigation
performances are mostly lower than the accepted values for most evaluated
systems and that the ten systems were varied in their uniformities of the applied
water.
Keywords: drip system, water uniformity coefficient, emitter clogging, field
evaluation, water distribution, water applied, Saudi Arabia.
1 Introduction
With population growth in the world, the demand of water is increasing and in
many parts of the world there are major concerns regarding the sustainability of
water resources for irrigated agriculture. Hence, the necessity for conservation of
