| Abstract | ||||
| Two field experiments were carried out under saline water irrigation conditions at Ras Sudr Experimental Station, South Sinai, Egypt during 2008/2009 & 2009/2010 growing seasons. The main objective was aimed to study the effect of tow saline irrigation water levels i.e. 3700 ppm and 6300 ppm on barley yield and some yield attributes i.e. plant height, number of tillers/plant, number of tillers/m2, number of leaves/plant, flag leaf area, peduncle length, spike length, biological yield and grain yield by using three different irrigation systems i.e. drip irrigation (DI), furrow irrigation (FI) and gated pipe irrigation (GPI) systems. Performed pipes which include 110 mm PVC pipes (6 bars) to convey water to the furrows in GPI irrigation system .Such pipe equipped with gated holes (25 mm) to control the water discharge. The distance between each hole is about 75 cm. Drip irrigation was performed by the distance about 40 cm between drip irrigation lines. The drip holes were about 20 cm between holes in the same line. Every irrigation system was irrigated by constant quantity of water as recommended for the region. The obtained results showed that increasing irrigation water saline level significantly decreased yield and all yield attributes studied of barley under the three irrigation systems. The high values of the growth characters and biological and grain yield were obtained by using drip irrigation system under 3700 ppm salinity followed by using gated pipe irrigation system compared with furrow irrigation system. Whereas under high saline irrigation water (6300 ppm) level the lowest values of all growth and yield and some yield attributes were obtained by using drip irrigation system compared with gated pipe irrigation and furrow irrigation systems. | ||||
