The effects of Rhizobium inoculation, lime and molybdenum supply on yield and yield components of Phaseolus vulgaris L. were investigated in a split-split plot design in the greenhouse and field experiment. Results showed that Rhizobium application significantly improved the number of pods per plant, number of seeds per plant, 100-seed weight and seed yield. Furthermore, compared with the zero treatment control, molybdenum supply significantly increased the number of pods per plant, number of seeds per plant, 100-seed weight and seed yield. In general, these parameters were significantly increased with molybdenum supplied at the highest rate of 12 g per kg of seed. With regard to lime, significant increases were recorded in number of seeds per pod and seed yield. Application of lime at the highest rate (3 t lime per ha) was significantly superior to the control and 2 t of lime per ha. The combination of these supplies at different levels resulted in significant interactions in some parameters and thus indicating need for these inputs in the study area
