In: The Bulletin Faculty of Agriculture, Cairo University 2002.v.53(1)Summary: Two field trials were conducted during two successive seasous (1997/98 and 1998/99) to evaluate the effect of inoculation with diazotrophs (Azotobacter chroococcum or Azospirillum brasilense) combined with either Bacillus megatherium var. phosphaticum or (V A M) Glomus mosseae in the presence of half dose of inorganic N-fertilizer on growth, chemical constituents, yield and volatile oil content of coriander plants. The results revealed that dual inoculation of coriander seeds with non-symbiotic N₂-fixers and phosphate solubilizers increased the available phosphorus content of the soil. This increase was accompanied by the highest values of phosphate dissolving bacteria densities and mycorrhizal root infection percentage. Combined inoculation of Azotobacter chroococcum and Glomus mosseae increased the values of nitrogenase activity and ammoniacal and nitrate nitrogen contents of coriander plant rhizosphere.
