Microbes, that are beneficial to plants, the group of Rhizobacteria such as Pseudomonas spp. and Bacillus sp. can serve as
fertilizer, as a means of biological control of plant pathogens and can increase plant resistance. This study aimed to determine the
activity of Pseudomonas spp. and Bacillus sp. in promoting germination and seedling growth of tomato plants. This is
experimental study using RBD basic design (Randomized Block Design). There are three treatments of tomato seed soaking time
is 10, 20, and 30 minutes with 3 types of suspension that isolates of Pseudomonas spp., Bacillus sp., and a mixture of both these
bacterial isolates. The study of tomato seed germination time showed that treatment of bacterial isolates is very real effect, where
the control slower germination 2-3 days, while the treatment of both types of isolates germination between 4-5 days. Tomato seed
treatment by soaking period of bacterial isolates between 10 to 30 minutes does not give a significantly different effect on the
time of germination and growth of tomato seedlings. Isolate the Bacillus sp. tends to give a tomato seedling growing faster than
the Pseudomonas spp. isolates, while a mixture of both isolate the bacteria does not give a different impression with a single
treatment. Among the three treatment isolates showed no significant differences, except compared to control.
