Özet

In the present study, effects of single, dual and triple combinations of phosphorus-solubilizing (Bacillus megatherium var. phosphaticum [M-13]) and N-fixing bacteria (Stenotrophomonas maltophilia [82] and Ralstonia pickettii [73]) treatments were compared with chemical fertilizer and control treatments with regard to barley efficiency parameters. Efficiency parameters of dual bacteria inoculation treatments yielded closer outcomes to chemical fertilizers and as much as 69.9% N uptake efficiency, 92.5% N translocation efficiency, 70.7% N use efficiency, 87.9% agronomic efficiency, 87.4% physiological efficiency, 87.9% water use efficiencies for grain and 78.7% water use efficiency for biomass of chemical fertilizers (N+P recommended dose) were achieved with dual (73 + 82) bacteria treatments. Nitrogen-fixing dual bacteria treatment (73 + 82) was followed by triple bacteria combination (73 + 82 + M3). Combined bacteria treatments offered environmental friendly practices for soil enhancement and improved yield levels in organic barley farming. Therefore, combined bacterial applications (73 + 82 and 73 + 82 + M3) can be recommended as an alternative fertilization method in organic barley farming.
