Biofertilizer Commonly Used in Fruit Science

Biofertilizer: Preparation containing live or latent cells of different strains of N-fixing, P-solubilizing micro-organisms used in soil or seed treatments with objective to augment the availability of nutrients to the plants.

Important Points

  • In citrus, G. fasciculatus increased growth by 70–300% depending upon citrus species.

  • In peach, VAM fungi in nursery stage had more Zn in their tissue upon inoculation.

  • About 95–99% of the total phosphorus are insoluble, which are not directly available to plants, so P-solubilising biofertilizers play a very significant role.

  • Leghaemoglobin provides oxygen to the root nodule bacteria even at the very low level of free oxygen.
