The experiment was out on carried plastic pots in the College of Agriculture and Forestry / Mosul University in the Agricultural seasons 2008 -2009 and 2009 -2010 to study the effect nitrogen fertilizer at rates: zero, 40, 80 and 160 kg nitrogen / ha -1 in the growth ,yield and quality of two wheat cultivars IPA 99, and um-Rabie. Um-Rabie Varity was superior to Variety IPA 99 in all growth characters, yield and quality in both growing season. Fertilization, at different rates, caused significant increases of the study season, as well as the interaction between the levels of fertilization and wheat varieties significantly in all characters of growth, yield and quality in both studied season too.
