In: Mansoura University Journal of Soil Sciences and Agricultural Engineering 2013.v.4(8)Summary: A Field experiment was conducted during 2011 - 2012 cultivation season at Sakha Agricultural Research Station Farm, Kafr El-Sheikh Governorate to evaluate the effect of some irrigation systems (surface irrigation "I1, semi portable sprinkler "I2", minisprinkler "I3". floppy sprinkler "I4", surface drip "I5:," and sub-surface drip "I6" and N application methods (100 % fertigation "N1", 75 % fertigation + 25% soil application "N2", 50 % fertigation + 50% soil application "N3", 25 % fertigation + 75% soil application "N4" and 100% soil application "N5") on wheat (var. Sakha 93} yield, N uptake, N use efficiency and soil .available N remained after harvesting. The main results could be summarized as follows: 1- Surface irrigation system (I1) and N, treatment achieved the highest values of wheat grain and straw yields, while the lowest values were recorded with subsurface drip irrigation system and N4 treatment. 2-I1 and N2 treatment gave the highest 1000 kernel weight, while I6 and N4 treatment gave the lowest value.
