Abstract
Field expcrtmcut was conducted under central poviet irrigation system at Krkok governor. Stcrilized seed of maize were inoculated with Ainspirillurn brasitlenses and Gtomus ntosseae in single and combiucd application under three levels of organic fertilizer. The result showed that thc percentage or seeds germantion, seeds vigour index and the concentration of IAi. ere markcdlv increased with combined inoculation of G. TI1I1SSeae and A. brasilicnscs, The ccnccntrarlon of IAA 186.3 ng. g. fwt" in thc treatment of combined inoculation and thc highcst level of organic ferrilizcr. Thc conccntratiou of AllA varies within leaves and the value 179 ng, g. fwr' compering with conccntrat lon of iAA a n d was reached 286. ng. g, fwrl at both treatments of combincd in ocu lation and the highcst level of organic fertilizer. The pcrccntane of root infection increased 1'1'011115°1., without adding organic fcrtilizcr to 46%, 69%, 10(]'10 highest level of organic fcrtilizer. A. brasilieuscs, G. mosses and A. brasilienscs + G. mosses respectively. Also the distribution of arbuselllcrs and vesicles are increased with adding org:lTlic fertilizer batleria and fungi.
