AbstractA field experiment was carried out in two seasons (autumn and spring) respectively in College of Agriculture University of Al - Anbar to study effect of nitrogen levels on some growth characteristics for six genotypes under different level of nitrogen Split plot design in R.C.B.D. with three replicates. Nitrogen fertilizer levels in main plot, while genotypes were arranaged as sub_plot .The results indicted that leaf area index and dry weight were a significant differences effect in genotype and nitrogen fertilizer However, the genotype IPA 5012 instrenght in growth where give highest rate to leaf area index amounts (3.922 and 3.830) for two seasons respectively, and excellence the same genotype lpa 5012 and single hybiridize (spiro-440663) in the dry weight, give weight amounts (353.66 and 365.55 gram/ plant) for two seasons respectively.
