Abstract
The aim of this study was to investigate the comparative effect of chemical fertilizers and ectomycorrhizal fungi on growth of Eucalyptus grandis W. Mill ex Maiden seedlings. Eucalyptus plants were inoculated with ectomycorrhizal fungus, which was Boletus edulis Bull. In addition, chemical fertilizer (DAP) was also provided to some Eucalyptus seedlings. All growth parameters (Height of plants, numbers of leaves, surface area of leaves, length of leaves, fresh and dry weight of roots, length of roots) were observed. These parameters show positive response towards growth in control group (with no treatment), chemical fertilizer group and mycorrhizal group. The plants inoculated with mycorrhizal fungus showed maximum growth of seedlings as depicted by all the parameters. This is due to the fact that mycorrhizal fungus act as a natural biofertilizer and fungal mycelium spread in the soil and increased the water and nutrient uptake by the plant roots from soil. Furthermore, fungal mantle provides protection against root pathogens in turns also improve vigor of the plants.
