Abstract:

Apolybag experiment was conducted in glass house of Department of Agricultural Microbiology, College of Agriculture, Raipur, Chhattisgarh with eight treatments replicated thrice to assess the impact of Rhizobium inoculation on performance of Albizia procera (Safed siris) and influence of nitrogen on biological nitrogen fixation. The treatments comprised of seedling root inoculation with A. procera - Rhizobium alone and along with 3 levels of N fertilization (N 1 , N 2 and N 3 as 50 mg, 150 mg and 400 mg N/seedling) and application of 3 levels of N alone including one control. It was observed that the plants treated with both Rhizobium and low level of nitrogen (150 mg/seedling) performed better than those, which received either one of them or none (control). Growth and biomass production of Albizia procera was found maximum in T 4 with shoot length (25.92 cm), root length (46.23 cm), collar diameter (4.01 cm) and total dry weight (10.965 g/seedling) at 120 DAT. Stunted growth and poor biomass production of Albizia procera-Rhizobium was observed when high level of urea 400 mg/seedling was applied. Based on results it can be inferred that application of N fertilizer at the rate of 150 mg/seedling along with Rhizobium inoculation has tremendous potential in improving initial growth response of Albizia procera plants in nursery. This finding may be helpful in producing quality planting stock of Albizia procera for afforestation programs.
