A field experiment was conducted in Al-Muthanna, Iraq, to study the effects of bio-fertilization Azospirillum brasilense and Glomus mosseae single, gathering, non-inoculation and three levels of organic matter (0, 1, 2% ) on growth of barley (Hordeum vulgare. L), grown on silty clay loam soil. Application of biofertilizer A3O2 significantly increased growth of plant in terms of plant, height, dry weight of stem, weight of 1000 seed, and available phosphorous by (94.40 cm, 2.27 gm plant-1, 28.50 gm, 27.46 mg kg-1), respectively. Plant inoculations with (Azospirillum brasilense and Glomus mosseae) improved plnat growth and available phosphors.
