Question

Which biofertilizer component is most effective for enhancing phosphorus and mineral absorption while providing pathogen protection?

Options

• Phosphate-solubilizing bacteria alone

• Mycorrhiza (fungus–root association)

• Nitrogen-fixing bacteria like Azotobacter

• Cyanobacteria in paddy fields

Answer 1

Mycorrhiza, a symbiotic association between fungi and plant roots, is particularly effective for enhancing phosphorus and mineral absorption due to the extended absorptive surface provided by the fungal hyphae. Additionally, mycorrhiza provides protection to plants from pathogens, making it a multifunctional biofertilizer component that addresses both nutrient availability and plant health concerns.
