This investigation has been performed in Mariout Research Station, Desert Research Center (D.R.C.) throughout two successive growing seasons of 2002 / 2003 and 2003 / 2004. Canary grass plants were raised under 9 treatments which were the combinations of 3 biofertilizer sources i.e. Azotobacter, Azospirillum and uninoculated control and 3 micronutrients i.e. 2% FeSo4, 1% MnSO4 and control. The treatments were arranged in split-plot design with three replications.           The important results obtained can be summarized as follows: 1-    Maximum values of all growth parameters tested of canary grass plants were obtained when seeds were inoculated with Azotobacter compared to inoculation with Azospirillum or uninoculated control. Fresh and dry forage yields followed the same trend of growth parameters in their response to the different biofertilizer resources. 2-     All growth and forage yield traits of canary grass plants were increased when the plants were sprayed with 2% FeSo4 compared to spraying with 1% MnSo4 or control treatment.
