Rhizospheric PGPR strains of wheat, barley and trefoil grown in Ağrı Province

The present study aimed to isolate potential plant growth rhizobacteria (PGPR) from various crops in agricultural areas Ağrı-Turkey and their characterization. For this goal, rhizospheric soil samples of wheat, barley trefoil were collected 12 different locations Ağrı province. Bacteria isolation studies carried out with these samples. Then, determine the PGPR properties each isolate; nitrogen fixation, phosphate dissolution, siderophore, ammonia HCN production tests performed. Molecular identification active isolates determined as suitable for development biofertilizers, biostimulants and/or bioprotectants was done by PCR sequencing applications performed universal 16S rRNA primers. According results, 29 molecular characterization done. These distributed Arthrobacter, Bacillus, Brevibacterium, Enterobacter, Pantoea, Pseudomonas, Microbacterium Stenotrophomonas according sequence similarities.
