<br/><br/> The field experimental work was carried out at the Experimental Research Station of the Agricultural Research Center, Sids- Ben Suief Govemorate during two growing season 2005/2006 and 200612007. The research aimed to study the effect of some engineering parameters designed of perforated pipes system as ouUets spacing, outlets diameters and number of outlets discharging simultaneously on the yield of wheat grains crop, application efficiency, distribution efficiency, and water use efficiency in order to choose the appropriate engineering parameters designed of perforated pipes system using for wheat crop production.
