Abstract

Growth and yield increases, obtained in nodulated soybeans growing in unamended sterile soil by inoculation with the vesicular–arbuscular (VA) mycorrhizal fungus Glomus mosseae, were accompanied by improved P uptake, lower root to shoot ratios, better nodulation with higher nitrogenase activity, and modifications in the pattern of the latter during plant growth. Stimulation of nitrogenase activity occurred early in plant development and preceded plant growth responses by about 2 weeks. Phosphate fertilization increased yield, percent P but not percent N of both mycorrhizal and nonmycorrhizal soybeans, and also modified the pattern and amount of nitrogenase activity during plant growth. Additions of 0.25 g KH2PO4/kg to the soil eliminated the mycorrhizal effect on plant growth, but nodule formation and nitrogenase activity were still significantly stimulated by the mycorrhizal infection. Mycorrhizal effects on nodulation were eliminated with 0.5 g KH2PO4 and on nitrogenase activity with the addition of 1.0 g KH2PO4. These higher levels of phosphate fertilization considerably diminished infection and, in particular, fungal spread within the roots.

Coinoculation of rhizobia and mycorrhiza has been tested in pulses including mung bean. the mycorrhiza make available nutrients like P to the plants and also increases surface area; provide moisture to plant; while rhizobia increse fertility of soil by fixing atmospheric N2.

Yes.There are several studies about positive effects on plant growth due to co-inoculation of Mycorrhiza and Rhizobium to plants.

Kindly search CABI abstracts for literature

Dear Mohammed,

It can be useful for you to look through RG profiles of Igor A. Tikhonovich https://www.researchgate.net/profile/I_Tikhonovich/contributions and Oksana Stark https://www.researchgate.net/profile/Oksana_Shtark/contributions

for tripartite plant-mycorrhiza-rhizobia symbiotic system is just their field of research.

With best regards,

Elena
