This study was planned as a two-year field trial so as to determine the differences in beans made by bacterial inoculation and molybdenum doses which are likely to have effects on yield and yield components. In this study, Akman 98 bean variety which has a widespread cultivation area as a plant material, three doses of molybdenum element (Mo0 =without molybdenum, Mo1=0.05 ppm, Mo2=0.10 ppm) which is effective in nodule and enzyme mechanism were used. For inoculation material, Rhizobium tropici (CIAT899) bacteria which belongs to the bean was used. The study was planned according to factorial randomized block experimental designs and set up with four replications. Some agronomic features such as plant height, number of beans per plant, grain yield, thousand grain weight and beans were investigated. Looking at the two-year combined data, it was demonstrated that molybdenum application and inoculation have a significant effect on the properties examined in bean plant. While increases in molybdenum doses generally resulted in increases in yield and yield components, the highest yields (350 kgda-1) were achieved in the case of co-administration of molybdenum and inoculation
