Effect of Bioinoculants on Growth of Acacia Nilotica Seedlings

Effect of bioinoculants on growth of Acacia nilotica seedlings was investigated. Plantlets inoculated with AM fungi in combination with Rhizobium attained more biomass as compared with due to either AM fungi or Azotobacter alone. Inoculum with a mixture of AM fungi resulted in more colonization than individual fungi. Glomus fasciculatum and G. epigaeum developed more colonization with higher resting spore population. There was significant improvement in the nodulation with Rhizobium while phosphorus content was more in the plants treated with AM and PSB.
