The effects of plant growth promoting rhizobacteria (PGPR) [(Pseudomonas BA-8 (biological control agent), Bacillus OSU-142 (N2-fixing) and Bacillus M-3 (N2-fixing and phosphate solubilizing)] were investigated on runner plant yield and quality of strawberry (Fragaria x ananassa) cultivars Selva and Sweet Charlie in the province of Erzurum, Turkey in 2002–2003. All PGPRs were inoculated on the roots of strawberry prior to planting. BA-8 and OSU-142 were sprayed on the leaves and flowers at 15-d intervals. Foliar + root application of PGPR strains significantly increased the number of runner plant per plant, leaf area and the ratio of usable runner plant in cv. Selva. Root application in cv. Selva increased the number of runner plant per stolon compared with the control. But in cv. Sweet Charlie, the most important increment was observed in foliar + root application compared with the control. In addition, the highest usable runner plant was obtained from foliar + root application in cv. Selva. The results indicated that Pseudomonas BA-8, Bacillus OSU-142 and Bacillus M-3 have the potential to increase runner plant yield and quality in strawberry cv. Selva and that foliar + root application was more effective than the other treatments.
