To evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. In this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassium releasing bacteria (KSB: Pseudomonas sp. S19-1, Pseudomonas sp. S14-3), phosphate solubilizing (PSB: P. putida Tabriz, P. fluorescens Tabriz) and nitrogen fixing (NFB: Azospirillum sp. Acu9, Azotobacter sp.), in the nursery cultivation. In addition, a control treatment without inoculation of bacteria (negative control) and a complete fertilized treatment based on the soil test analysis (positive control) were included to compare the results. The results showed that inoculation with bacteria had significant effect on average fruit weight, fruit length, number of total fruits, the percentage of marketable fruit, and the percentage of BER incidence and Potassium content of fruit. The highest number of total fruits was obtained in the PSB treatment. The highest average fruit weight, Potassium content of fruit, the percentage of marketable fruit, fruit length were observed in KSB treatment with values of 54/11g, 4.7 mg/g, 56.71 percent and 51 cm respectively. The lowest percentage of BER incidence was observed in KSB with values of 6.24 percent.
