The current study was aimed to isolate and diagnosis Bacillus mucilaginosus and evaluate its use as biofertilizer alone or interfere with Glomus mosseae on growth and yield of corn (Zea mays L.) Randomized completely block design was used at the Field of College of Agriculture- University of Baghdad  Al-Jadriya in silt clay loam soil. The biofertilizer was used  alone or as combination that added with or without 50 Kg P ha^­¹ of rock phosphate and with or without 120 Kg K ha^­¹ while, 250 Kg N ha^­¹ was added as urea (46%N) to all treatments. Results showed the superiority of bacterial or fungal biofertilizer on enhancing all growth traits of corn and the addition of  B . mucilaginosus together with Glomus mosseae  resulted superiority for plant height , dry weight of vegetative part , grain yield and biological yield with the values 229.4 cm , 180.7 gm .plant^­¹,12.17 tons ha^­¹ and 19.59  tons ha^­¹ respectively. As well as treatment gave significant increase equal the increase in the yield due to addition of completely recommended mineral fertilizer which was 12.14 tons ha^-1 .
