A field experiment was carried out with the use of complete randomized block design (CRBD) to study the effect of five bacterial inoculations (non- inoculation, inoculation with phosphate soluble bacteria, inoculation with Azotobacter bacteria, inoculation with Pseudomonas fluorescens and Bacterial mixture). Two levels of salinity of irrigation water 3 and 6 dS.m-1 and four levels of phosphate fertilizer (0, 40, 80 and 120 kgP.ha-1). The results showed that the mixed inoculation of phosphate soluble bacteria, Azotobacter and P. fluorescens bacteria were superior to the rest of the single bacterial inoculation in plant height, dry weight of the shoot part, total grain yield, weight of 100 grains, grain weight in cop, leaf surface area, nitrogen, phosphorus and potassium concentrations in the vegetative growth and grain with 33.08%, 31.90%, 61.07%, 44.99%, 62.06%, 36.94%, 12.8%, 31.5%, 156.5%, 272.3%, 39.5% and 75.1%, respectively, in comparison with the non- inoculation and irrigated water treatment of 6 dS.m-1 (T0S2P0), while the inoculation of phosphorus soluble bacteria did not differ significantly from the P.fluorescence inoculation in most of these traits. T3S2P3 was not significantly differ from T4S2P3 combined in the increase of plant height and total grain yield compared to the non- inoculation and non-phosphorous treated at the salt level 3and6 dS.m-1. The single-dose T2S2P3 did not differ significantly from the combined T4S2P3 3 and 6 dS.m-1.
