Abstract
This research was conducted with the aim of evaluating the efficiency of two types of beneficial bacteria , Basillus subtilis and Pseudomonas flourescens in improving the growth parameters of tomato plants infected with the pathogenic bacteria Pseudomonas corrugata. The research results showed an increase in all the values of all studied parameters presence of (Plant height, fresh and dry weight of shoots, and fruit weight) when inoculated with beneficial bacteria in the absence and presence of infection with pathogenic bacteria and a reduction in the effect of pathogenic bacteria on plant growth parameters. Inoculation with beneficial bacteria singly or in a mixed achieved a significant increase in all studied treatments compared to the healthy control. The results showed that Basillus subtilis bacteria was outperformed with a statistically significant difference compared to Pseudomonas fluorescens bacteria. Mixed inoculation treatments with a mixture of the two types of beneficial bacteria were the best in stimulating growth plant and reduce the effect of pathogenic bacteria.
Keywords: Bacillus subtilis, Pseudomonas fluorescens, Plant growth, Tomato pith necrosis disease.
