In this study, the effect of bacterial application on input utilization in strawberry cultivation was investigated. The study was carried out with Festival strawberry varieties in unheated farmer greenhouse in Antalya. In the research, the farmer application was taken as a control and the amount of NPK (Nitrogen, Phosphor, Potassium) fertilizer used by the farmer was reduced by 33% and 66%. In addition, Rhizobium SY55 with fixing feature of N, Bacillus SK63 with Psolving property and Herbaspirillum SY48 bacterial strains with Kfixing were applied to the root region of half of the strawberry plants at each fertilizer level by mixing 1: 1: 1 ratio. In the study, yield per plant and per decare was determined, the amount and costs of fertilizer used per decare, and per plant were calculated. According to the results, bacterial application decreased amount of fertilizer used and costs and increased the productivity per unit. The increase in income due to the increase in productivity was also determined. In addition, products increased the market competitiveness due to the increase in revenue by reducing the production costs. With these characteristics of bacterial application, it can be said that it is suitable to the universal principles of sustainable agriculture.
