A. niger wasisolated and diagnosed, using 2 fungal isolates in different areas ( taji, abughraib) the most efficient isolate of solublizing phosphorous in rock phosphatein Martins Medium for fungi was chosen and used as bio fertilizer in theexperiment . Mycorrhiza was collected from the (Ministry of science andTecnology) that consists of (spores + infected mycorrhizal roots and dry soil) .Results showed that there was a significant increase in plants heights ,shootsdry weight when bio fertilizers applied individually or as group . they showedhighest values in the first period of growth (branching ) when bio fertilizersapplied in an interacted way (G.mosseae and Aspergillus niger) where values ofplant heights were (14,15) cm and the dry weight of shoot system were(7.40,7.80) gm/pot when addition the equivalent recommendation of fertilizersand double recommendation of fertilizers of rock phosphate respectively . also,the application of fungal bio fertilizers individually and pairly led to asignificant increase in the shoot system of phosphorous (0.2035,0.2218)% andphosphorous in soil (20.76,29.52)mg kg-1 . the highest values were in the firstgrowth period (branching stage) when double bio fertilizers applied andaddition equivalent recommendation of the fertilizers and doublerecommendation of fertilizers rock phosphate respectively ., wheat rootsinfection ratios were increased significantly when fungi available with same of(G.mosseae and A. niger ) as compared to the application of Mycorrhizaindividually ,while results showed a decrease in the infection ratio in wheatplants roots when recommendation and double recommendation of rockphosphate application
