Abstract: The aim of this study is to investigate the possibility of using minisprinkler, gun, floppy sprinkler, surface drip, subsurface drip and modified surface irrigation (using gated pipes) systems in maize and barley crop production in the land of the old valley. Also, studying its effect in minimizing water losses and increasing the production of some agronomic Practices related to different irrigation systems on the water use efficiency and yield of maize and barley grown on loamy clay soil. A field experiment was carried out at Sakha Agricultural Research Station at Kafer EL-Sheikh governorate, Egypt through summer season 2004 for maize and winter season 2005 for barley. Conventional (leveled by laser technology) surface irrigation method was considered for comparison. Data indicated that. Irrigation by gated pipes achieved the highest values of maize, barley grain yield and its components followed by minisprinkler and gun irrigation methods. On the other hand, floppy sprinkler, and subsurface drip irrigation methods recorded the lowest values foi^hp^tyield. While, floppy sprinkler, subsurface and surface drip img&fen methods recorded the lowest values for barley yield. Sprinkler and drip irrigation methods with maize crop were saved amount of irrigation water applied by 11.25 and 22.7 % respectively compared to gated pipes. While, sprinkler, drip and gates pipes irrigation methods were saved amount of irrigation water applied by 21.8, 31.9 and 11.9% respectively compared to conventional (leveled by laser technology). Sprinkler and drip irrigation methods with barley crop were saved amount of irrigation water applied by 14.4 and 22.6% respectively compared to gated pipes. While,
