Onion Yield Boost

Onion Yield Boost

Inoculating Welsh onion (Allium fistulosum) seedlings with Rhizophagus fungi increased yields over a 3-year trial, even when phosphorus fertilizer was reduced or eliminated. Mycorrhizal dependency reached 15%, showing fungi can help replace synthetic inputs in farming.
