e0“In a glasshouse trial, pigeonpea (Cajanus cajan) was grown in a Vertisol from the Darling Downs, Qld”
e5“Zinc fertilizer (15 mg kg-' soil) without Phytophthora inoculation was fungitoxic to the mycorrhizae, decreasing per cent VAM colonization and depressing plant growth”

Other claims from this paper (16)
- Intervention effect Mycorrhizal pigeonpea plants reached about 3.3 times the dry weight of non-mycorrhizal plants.
- Association Shoot dry weight was exponentially related to per cent VAM colonization of the root length (R value 0.904).
- Association Zn concentration of the shoots was exponentially related to per cent VAM colonization of the root length (R value 0.644).
- Association Shoot P concentration was linearly related to VAM colonization (K value 0.888).
- Intervention effect VAM inoculation increased P concentration and P uptake.
- Intervention effect VAM inoculation increased Zn concentration and Zn uptake.
- Intervention effect VAM inoculation increased the P/Zn ratio.
- Intervention effect Zinc fertilizer without Phytophthora inoculation decreased per cent VAM colonization.
- Intervention effect Inoculation with Phytophthora drechsleri (Pdr) did not result in infection or root rot symptoms in pigeonpea.
- Intervention effect Pdr inoculation overcame the zinc toxicity of Zinc fertilizer without Phytophthora inoculation.
- Intervention effect Pdr inoculation enhanced VAM colonization in zinc-treated pigeonpea.
- Mechanism Pdr inoculation may overcome zinc toxicity in pigeonpea through organic chelation effects.
- Intervention effect The greatest VAM colonization was obtained with combined VAM inoculation, Pdr inoculation, Zn and P.
- Intervention effect The combined VAM, Pdr, Zn and P treatment gave the best plant nutrition and growth.
- Association Pigeonpea growth was highly dependent on mycorrhizal colonization of the root system after VAM inoculation.
- Recommendation Maintaining adequate VAM fungi levels in soil through appropriate agricultural practices is recommended to maximise pigeonpea growth.
