SUMMARY Studies were conducted to assess the effect of different components of VA mycorrhizal inoculum on growth of onion. The associated micro‐organisms and sterilized root segments, did not significantly influence the growth and phosphorus nutrition of onion. Application of mycorrhizal inoculum containing extramatrical chlamydospores and infected root segments containing mycelium, vesicles and arbuscules had a significant effect on shoot and root weight, and phosphorus content of the plant. Further fractionation of inoculum indicated that chlamydospores are the important component, since plants inoculated with chlamydospores produced more dry matter and contained more phosphorus.
