The experimental work was carried out at El-Gemmeiza Agricultural Research Station, Gharbia Governorate, Egypt during 2009/2010 winter growing season to study the effect of using sprinkler irrigation in clay soil condition and barley production. The sprinklers layouts were square and triangular. Also, two irrigation levels and two fertilizers levels were used. The results showed that the amounts of applied water were 5077, 4201 and 3068 m3 ha-1 for flood and sprinkler 100% ETc and 50% ETc, respectively. The highest values of coefficient of uniformity, distribution uniformity and application efficiency of low quarter were achieved by the square layout. Grain yield increased from 4.55 Mg ha-1 with flood to 5.70 Mg ha-1 under sprinkler irrigation with square layout at 100% ETc and 100% fertilizer. Straw yield increased from 5.36 Mg ha-1 with flood to 9.65 Mg ha-1 under sprinkler irrigation with square layout at 100% ETc and 100% fertilizer. Water use efficiency increased from 0.90 kg m-3 with flood to 1.64 kg m-3 under sprinkling method with triangular layout at 50% ETc and 100% fertilizer. Energy use efficiency increased from 13.66 kg kW-1 h-1 with flood to 18.20 kg kW-1 h-1 under sprinkler irrigation with triangular layout at 50% ETc and 100% fertilizer.In conclusion, square layout at 100% ETc with 100% fertilizer gave the best results.
