Abstract: The present study consists of the experiments on application of mineral solubilizing and plant growth hormone producing microbial strains in individual and /or combination under glass house conditions and their impact on enhancement in plant productivity of Adnenthera pavonina. Among microbial strains taken for the study, 6 phosphate solubilizing fungi, 4 iron ore leaching fungi, 5 phsophate solubilising bacteria and 11 isolates of Rhizobia had been used. Screening of ten fungal species and 5 bacterial isolates for their effects on growth of Adnenthera pavonine, done under pot culture in green house conditions, elucidated the best performance of Penicillum crysogenum Thom. 1 and Cunninghmella elegans Lendn. Combination of selected microbial inoculants for the individual test tree species were evaluated for their individual performance and /or in combination with the other selected inoculants in specific ratio of their inoculums. Under the dual inoculation experiment, selected mineral solubilisers (fungi/bacteria) were evaluated along with the combination of different isolates of Rhizobium and resulted selection of Penicillium chrysogenum and Cunnighmella elegans in 1:1 combination for better growth and development of seedlings under nursery conditions. The impact of Rhizobium inoculation alone or in combination with these fungal strains could not be observed and interpreted. However, the outcome the present study done under controlled experimental conditions may provide the plausible approach towards the development of nursery package and practice for development of quality planting material of this tree speices may be useful for the transplantation programe of revegetation of degraded land and environment.
