AbstractA field trial was carried out during season of 2009-2010 at farmer Field in Garma–Falluja town–Anbar governorate to know the effect of four levels of nitrogen fertilizer ( 50 , 100,150 and 200 Kg N. ha-1) on growth and yield characters of two bread wheat cultivars (IPA 95 and Fatth).
A split plot arrangement in randomized complete block design with three replicates was used.
Tow cultivars (IPA 95 and Fallah) were the mean plots and nitrogen levels (50 , 100,150 and 200 Kg N. ha-1) were the sub plots.
The results showed that IPA 95 cultivars gave significant increment in most of studies characters except for 1000-kernals weight.
Application higher level of nitrogen fertilizer (200 Kg N. ha-1) increased plant height, flag leaf area, number of spikes per m2, number kernels per spike, 100-kernals weight and total grain yield (ton. ha-1).
The interaction between the cultivars and nitrogen levels had significant effects for all studies characters. IPA cultivar plants with 200 Kg N. ha-1 gave high mean for plant height ( 98.5 cm) and total grain yield (8.02 ton ha-1) .
