This study was conducted to determine the effects of inoculation bacteria on mineral content, yield and growth in rocket. Strains of bacteria, Burkholderia gladii BA-7, Pseudomonas putidae BA-8, Bacillus subtilis OSU-142 and MFD-5, Bacillus megatorium M3, Agrobacterium rubi A-1, A-16 and A-18, were used. The effects of the bacterial treatments on the plant nutrient elements of leaves were evaluated. The parameters of yield per m(2), average leaf number, leaf weight, leaf length, leaf stem diameter, leaf area, leaf dry matter and average root length, root weight and root dry matter were also determined. The effects of bacterial application on plant mineral contents were significant. Bacterial applications increased mineral contents of rocket leaves as compared to control treatment. All bacterial applications particularly affect on increasing in N, K, P, Zn, Fe, Mn, Na, Ca and Mg contents of plant. The effects of bacterial application on the parameters were also significant. The highest yield (4586.54 g/m(2)), average leaf weight (1.63 g), leaf length (27.48 cm), leaf stem diameter (2.06 mm), leaf area (93.57 cm(2)) and root weight (0.60 g) were obtained from Pseudomonas BA-7 applications as comparing to that of the other applications. The highest leaf number (8.23), leaf dry matter (6.70 %) and root dry matter (11.85 %) were determined in A-18, BA-142 and MFD-5 applications, respectively. The results of this study showed that especially Burkholderia gladii BA-7, Pseudomonas BA-8 and Bacillus OSU-142 have a great potential to increase the parameters of plant growth of rocket.
