Growth promoting effect of microbial inoculants on Acacia nilotica grown under nursery conditions

Present study was carried out on Acacia nilotica seedlings grown under different bioinoculation treatments by using laboratory grown liquid cultures of 10 fungal isolates,11 Rhizobium isolates and 5 other bacterial isolates.Microbial cultures were screened for their effects on growth of Acacia nilotica grown in greenhouse conditions.The selected microbial inoculants were assessed as considering their individual performance or in combination with the other inoculants in specific ratios.The higher performance was shown with the combination of Penicillum chrysogenum Thom.1,B 5 bacterial isolate,R10 and/or R11 isolates of Rhizobium.Further,it was observed that the above microbial mixed culture inoculation was promoted plant growth specifically number of leaves and the leaf biomass.Therefore,nursery application of mixed microbial inoculants,specifically as above could be beneficial for the production of quality planting material(QPM)of Acacia nilotica and subsequent field applications.
