“Two field experiments were conducted in sandy soil at El-Bustan region, El Behera Governorate during two winter successive seasons of 2004/2005 and 2005/2006 to evaluate the effect of five nitrogen fertilizer levels (71.5, 143, 214, 286, and 357 kg/ha) represented (25, 50, 75, 100 and 125% of the recommended dose) and some isolates of nitrogen fixing bacteria (Azospirillum sp,, Azotobacter sp, Bacillus sp.and Klebsiellasp.) on growth and yield of six bread wheat lines”
