    Abstract

    Fluorescents of bacteria such as Pseudomonas aeruginosa is well known as PGPR that also involve in the decomposition of organic matter. Tobacco H-877 and CMV used as a model to observed that bacterial function. In the semi aerobic conditions, the role of synergistic EM4 and P. aeruginosa to decompose vegetable sewage was more effective, as shown by the low of C/N ratio on any compost extracts process (P< 0.05) than on compost amended with either one of these microbial, although these effects were not significantly different. It was assumed there was any changing in P, K content and pH of the growth medium within treatments, that considered was caused by the activity of synergistic microbial to use the substrate for growing up. The chemical content and soil pH media within treatments of bacteria and virus seemed not different, although the rich nutrient increased the number bacteria populations in rhizosphere and roots. Any treatments of different extract compost processes and it’s application to the plant did not affect the plant fresh and dry weight, and the root densities, however, it was affect the root length and LAI, particularly on plant infecting with virus. The available nutrient in the medium caused any bacteria introduced were more rapidly to colonize rhizosphere and roots. The bacteria population was higher on plant infected with virus rather than on plant not inoculating with virus. Therefore, the role of synergistic EM4 and P. aeruginosa in the compost extract as PGPR to solubilize P was much better after 40 days incubating, and the population both of them increased. Key words: PGPR, water extract compost of vegetable sewage, nutrients of growth medium
