To assess the effect of multifunctional rhizobacteria on yield of mungbean, a trial was laid out using different multifunctional rhizobacteria viz., Kalaburagi (GUR5 & GUR8), Akola (WUR 12-1), Vamban (VUC), and Pantnagar (A-3, P-5 & PUR 34), received from various AICRP centres. A total of four multifunctional rhizobacteria were obtained from three different AICRP centres viz., Pantnagar, Coimbatore and Ludhiana. Multifunctional rhizobacteria promotes plant growth through nutrient mobilization, growth hormone secretion and protects the plants from pest/diseases. Mungbean seeds were treated with all the multifunctional rhizobacteria along with the local best Rhizobium BMBS 47. Observations were recorded at 45th DAS to assess their effect on plant growth parameters viz., number of nodules /plants, root length and shoot length and nodule dry weight and yield parameters at harvest. Among rhizobacteria Methylobacterium (Coimbatore) recorded a greater number of nodules/plant (53.3/plant) and nodule dry weight (0.069 g/plant) which is higher than other rhizobacteria. This was followed by NE 10 (Bacillus cereus) (Pantnagar Ch.) which recorded 44.3 nodules/plant and nodule dry weight (0.057 g/plant). Uninoculated control recorded the least nodulation as 23/plant which is significantly lesser than all the other treatments. Among the different rhizobacteria Methylobacterium (Coimbatore) inoculated treatment recorded the higher yield of 1115.3 kg/ha followed by NE 10 (Bacillus cereus) (Pantnagar Ch.) (990 kg/ha).
