A nursery experiment was conducted to assess the performance of Albizia procera to Rhizobium inoculation alone and along with 3 levels of N fertilization (N1, N2 and N3 as 50mg, 150mg and 400mg N/seedling). Also to study the influence of Nitrogen on biological fixed nitrogen by A. procera. The A. procera –Rhizobium isolate tested as acidic (5.0 pH) tolerant and salt (30000ppm) tolerant. Due to inoculation in Albizia procera, 2.6 times increase in biomass accumulation was seen, N uptake was increased from 9.293 to 41.326 mg/seedling at 120DAT and nodulation increased from 0.117 to 0.0.412 g/seedling at 90DAT. However significantly maximum biomass accumulation (10.96g/seedling), extra N gain ( 55.44 mg/seedling over control at 120DAT), nodule no. (68/seedling) and nodule dry weight (0.483g/seedling) at 90DAT were obtained at Rhizobium+N2 treatment. Inoculation of Albizia procera was significantly effective and nitrogen application (150mg/seedling) along with inoculation further significantly enhanced symbiotic traits in Albizia procera.
