Abstract
The study was carried out using different irrigation methods i.e. sprinklers with different spaces 9×9 m, and 12×9 m, drip irrigation GR, surge flow and the traditional surface irrigation as control, at Mokhtaria Research Station, Agricultural Research Center in Homs, Syria, started from 2008 to 2012 seasons. The results showed that using irrigation methods (sprinklers 9x9m, sprinklers 12x9m, drip GR, surge flow drainage 0.75 L/sec/row and surge flow drainage 0.50 L/sec/row) gave an average of gross water consumption as follow: 4313, 4717, 3592, 4617 and 5190 m3/ha, respectively, while the percentage of irrigation water saving was (49.2, 45.5, 56.5, 51.1, and 45.1%) respectively, and the yield was (6756, 6258, 7278, 6088, and 5818 kg/ha), respectively, and the increase in yield compared with control was (71, 58, 84, 54, and 47%), respectively, gross water use efficiency was (1.57, 1.33, 2.03, 1.32, and 1.12 kg/m3/ha), respectively. The average of gross water consumption of the traditional surface irrigation was 9447 m3/ha with a yield of 3956 ton/ha. The results above showed that drip irrigation (GR) was the best in yield and saving irrigation water, and was the highest in gross water use efficiency as compared with other irrigation methods, and it is recommended to be executed as modern technique for irrigation of maize crop in Homs Governorate.
Key words: Water use efficiency, Different irrigation methods, Maize, yield.
