| Abstract | ||
| The field experimental work was carried out at the Experimental Research Station of the Agricultural Research Center, Sids- Ben Suief Governorate during two growing season 2005/2006 and 2006/2007. The research aimed to study the effect of some engineering parameters designed of perforated pipes system as outlets 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. The results indicated that: 1- The water advance time, water recession time and the infiltration opportunity time were more efficient in case of treatment (3). 2- The water distribution efficiencies (WDE) are closed to each other for all treatment. 3- The highest values of water application efficiencies and The water use efficiency were achieved in case of treatment (3) and saving about 14.5% of irrigation water applied in average. 4- The uniformity distribution of the perforated pipe system decreased as the number of outlets discharging simultaneously decreased. As a general recommendation using a perforated pipes system having engineering parameters described as treatment T3 (12 outlets, outlet diameter 36mm, 1.0 m spacing, and between two consecutive outlets and outlet flow rate about 2.0 l/s) giving a highest values of both water application efficiency and water use efficiency of the yield of Wheat crop and received less amount of irrigation water than another treatment. | ||
