Field experiment was conducted in Al-jazeera region-Albuassaf at spring season 2017 in silty loam soil to know the role of A. chroococcum and G. mossae in bio-fertlilizer individulty , mixed and inter feransce bio-fertlilizer with meniral fertilizers on Potato growth and yield Burren class. Results showed that biological bio-fertilizer with increased some vegetation growth parameters (height, Aerial stalks, Numbers, Dry weight, potato yield and total potatoes yield), Quality parameters (percentage of Dry material, starch and protein), The interaction in the studied factors gave increasing in vegetation Azotobactor, Mycorhyza and Meniral fertilization individualy significantly growth and quality and quantity properties of potato. The tri interaction between biological bio-fertilizer with A. chroococcum and G. mossae and Meniral fertilization gave the highest values in vegetation growth quantity and quality properties of yield for all he studied treatments compared with Dry, individual and control treatments which recorded highest mean at level 75% of fertility with Intermixed bio-fertilizer of Aerial stalks number, Dry weight of vegetation part which reached 7.33 stalks, plant1,318.3 gm.plant-1 respectively and qualitative yield properties (mean of tubers weight 161.55 gm.plant1, quality properties like dry matter 8.11Mecagram.ha-1, yeild of plant 1918.7gm.plant-1 , total yield 42.64Mecagram.ha-1, yield of marketing 39.85 Mecagram.ha-1 and percentage of starch and protein content reacted 13.03 , 9.87% respectively.
