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”
e6“lnoculation with Pdr did not result in infection and root rot symtoms”
e7“it did overcome the Zn toxicity, possibly through organic chelation effects, and thereby enhanced VAM colonization”

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 Zinc fertilizer without Phytophthora inoculation depressed pigeonpea plant growth.
- 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.
- 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.
