Abstract: A Pot experiment was conducted at the greenhouse of Microbiology Department, Soils Water and Environment Res. Inst., ARC, Giza and a field experiment was carried out at the experimental saline sodic soil at Sahl El-Tina ,North Sinai, in winter season of 2010-2011 to evaluate the response of wheat plant cultivar Sakha 93 to inoculation with Basillus subtilis and Pseudomonas fluorescens isolates, isolated from salt affected soil of Sahl Eltina Valley. Results revealed that plant height, fresh and dry weights and chlorophyll content of wheat significantly increased as a result of inoculation with single or dual isolates. Inoculation did alleviate the harmful effect of salinity on wheat development and significantly increased plant height (72cm) and dry weight (14.1g/plant) through the growth period. Also, spike weight (3.21ton fed-1) and grain yield (1.85ton fed-1) significantly increased. Inoculation with both isolates significantly enhanced the activity of dehydrogenase enzyme in the rhizosphere and crude protein of wheat grain. Concentrations of N, P, K of wheat grain significantly increased (57.6 , 53.6 , and 35.4% respectively) by inoculation, the isolate mixture led to the highest values of N and P while inoculation with Pseudomonas fluorescens recorded the highest caused the maximum records of K and Na levels.
