The rhizospheric soil samples were collected from five different sites of Northeast India where Oroxylum indicum was naturally growing in its ecological habitat and were analysed. A total of 25 fungal species and four bacterial isolates were found to be associated in the rhizosphere of O.indicum. The fungal microbiota comprised mainly of Trichoderma harzianum, Penicillium sp., Aspergillus sp., Trichoderma viride, Fusarium sp., Penicillium funiculosum, Penicillium capsulatum, Penicillium citrinum, Pachybasium sp., Trichoderma hamatum, Mucor sp., Verticillium sp., Curvularia sp., Rhizomucor sp., Pythium sp., Rhizoctonia sp., Colletrotrichum sp. etc. While the bacterial isolates mainly comprised of Four bacterial isolates Pseudomonas putida, Pseudomonas sp., Streptobacillus sp., Bacillus sp. The overall analysis of soil nutrient status showed that pH status was higher in roadside and riverside, while mimum pH was found in forest fringe and hillslope. The % Organic Carbon was found to be highest in agricultural farmland and lowest in hillslope. Available Nitrogen was highest in agricultural farmland, while it was minimum in forest fringe. Available Phosphorus was again highest in agricultural farmland while it was lowest in riverside and forest fringe areas. Available Potassium was highest in hillslopes and agricultural farmland while it was lowest along riverside.
