Two field experiments were conduced during the two growing seasons of 2004/2005 and 2005/2006 at Sakha Agricultural Research Station Farm to Study the effect of different border widths, irrigation discharge and nitrogen fertilizer levels on wheat crop yield. The split split plot design with four replicates was used. The main plots randomly assigned to three border widths (7, 11 and 15 m), the sub plots to three irrigation discharges (2.5, 3 and 3.5 L.sec^-1m^-1) and the sub sub plots to three nitrogen fertilizer levels (80, 100 and 120% N) from recommended dose (75 kg N
fed^-1).                 The results revealed that the combination between 11 m border width, 3.5 L.sec^-1m^-1 and 120% N from recommended dose increased wheat grain, straw and 1000 grains weight in the two season of study followed by the treatments; 15 m border width, 3 or 3.5 L.sec^-1m^-1 irrigation discharge and 120% N from recommended dose. Moreover, the above mentioned treatments produced the highest protein percentage.                 The highest concentration of nitrogen and its uptake by wheat grains and straw were achieved with 11 m border width, 3.5 L.sec^-1m^-1 and 120% N from recommended dose. While the highest values of fertilizer use efficacy were achieved under 15 border width, 3.5 L.sec^-1m^-1 water discharge and 120% N from recommended dose.                 It could be concluded that the interaction between 11 m border width, 3.5 L.sec^-1m^-1 water discharge and 120% N from recommended dose achieved the best highest wheat yield at North Nile Delta.
