A study was conducted in green house of Department of Agricultural Microbiology, College of Agriculture, Chhattisgarh during 2015-16 to study the effect of Rhizobium and Phosphorous Solubulizing Bacteria inoculation on growth performance of Acacia nilotica. The treatments were inorganic fertilization only, inoculation with Rhizobium, PSB alone and along with 25 per cent N including control. The Rhizobium isolate from nodule of A. nilotica was found good in its growth at 300C and 6.5-7.5 pH but showed tolerance up to 500C and pH 5.5 to 8. PSB isolate, isolated from rhizosphere zone of A. nilotica plant was found to survive at pH 5, however pH 6 to 7 was found most suitable for its growth. A. nilotica - PSB showed well growth at temperature 300C and decreases with increasing temperature from 350C to 500C. Dual inoculation of A. nilotica with Rhizobium and PSB along with addition of 25 % nitrogen recorded significantly higher shoot length (78.75 cm), root length (53.75cm), collar diameter (6.15mm) and shoot dry biomass accumulation (7.66 g plant-1) over other treatments at 90 DAT. Significantly higher nodulation (38no. and dry weight of nodules 0.283g plant-1) also recorded with Rhizobium + PSB +25 % N at 60 DAT.
