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)] on yield and some fruit properties of strawberry cultivar 'Selva' in the province of Erzurum, Turkey in 2002-2003. Foliar + root application of PGPR strains significantly increased yield per plant as compared with the control. Root application of PGPR strains significantly increased total soluble solids, total sugar and reduced sugar, but decreased titratable acidity. It was also determined that bacteria applications have no important effect on the average fruit weight and pH. The results of this study suggested that Pseudomonas BA-8, Bacillus OSU-142 and Bacillus M-3 have potential for increasing yield in strawberry plant. © Taylor & Francis Group, LLC.
