Growth Performance of Casuarina junghuhniana Seedlings Inoculated with Biofertilizers (Research Article)

Author(s): T. Vairamani* and K. Rajendran

Abstract: Nursery experiments were conducted to select suitable biofertilizers to improve the growth and biomass of Casuarina junghuhniana. Two months old clones of C. junghuhniana were transplanted to polythene bags with a potting mixture of unsterilized substrate and inoculated individually and in combinations with Azospirillum, Paenibacillus polymyxa and AM fungus. Uninoculated plants were maintained as control. Shoot length, root length, basal diameter, root weight and shoot weight were recorded after six months. Results showed that the total seedling length and biomass were significantly increased in all the treatments compared with the control plants. The seedlings inoculated with the combined application of Azospirillum + Paenibacillus polymyxa + AM fungus produced the maximum growth and biomass.
