In Egypt most of the newly reclaimed lands depend mainly on drip irrigation systems. The selection of good and appropriate drippers is the first step for successful drip irrigation system design. As well as, the uniformity of water application from drip irrigation system is affected by both water pressure distribution in the pipe network and hydraulic properties of drippers. Therefore, this study aimed to evaluate some irrigation drippers under different operating pressures and spacing on different lateral lengths widely used in Egyptian agriculture. The required hydraulic tests and measurements were conducted at National Irrigation Laboratory of Agricultural Engineering Research Institute (AEnRI), ARC. MOLAR, Egypt. These tests were carried out using 11 drippers of normal (non pressure compensated) and pressure compensated, on line and in line types of drippers with nominal discharges of 2, 4. and 8 L/h. All the drippers were tested and replicated thrice at operating pressure (0.5 ,0.75. 1 and 1.25 bar), while all the drip irrigation lateral lines tests were at 100 bar operating pressure for treatments of 0.25, 0.50 and 1.00 m dripper spacing on PE lateral lines of 25, 50 and 75 m lengths and 16 mm diameter.
