Use of fertilizers is important in agricultural production. In particular, it is more focused on organic fertilizer that increases yield and quality of crops and is not harmful to environment at the same time. In this study, the effect of bacterial biofertilizers on yield and some quality parameters were analyzed in two tomato cultivars (Solanum lycopersicum L., cv. Cevahir F1 and Pala F1) in greenhouse conditions. Three different concentrations (1, 3, and 5 gL-1 and control i.e. un-inoculated) and two different bacterial fertilizers including A: Azotobacter spp. (1×109 CFU), and B: mixture of Bacillus subtilis and Bacillus megatarium (1×109 UFC) were evaluated in a completely randomized design with 3 replications. The treatments were applied one week after planting of the seedlings. The solutions were given to the root zone of the plant and repeated 3 times at intervals of 10 days. Average fruit weight, fruit number per plant, fruit weight per plant, plant height, fruit width and length, total soluble solid, pH, ascorbic acid, chlorophyll content, dry matter yield and mineral content were evaluated on tomato. The effects of treatments were found significant on plant growth parameters. Bacterial fertilization increased yield and other parameters in all treatments. Besides, the effects of treatments were significant on mineral content of tomato fruits.
