Abstract: The aim of the research was to find out the effects of bacteria inoculation, four different nitrogen (0, 20, 40, 60 kg ha-1 N) and four different phosphorus doses (0, 40, 60, 80 kg ha-1 P2O5) on field bean in Van-Turkey ecological condition. Although the effects of the applications showed differences depending on years, nitrogen application exerted a significant and positive effect on pod number, grain yield and raw protein proportion, whereas no significant effect was seen on seed number per pod and weight of thousand seeds. As for the effects of phosphorous doses, they weren’t found to be significant for all of the factors. On the other hand, bacteria inoculation exerted a significant and positive effect on pod number per plant and grain yield, whereas no effect of this application was seen on weight of thousand seeds and raw protein rate.
