Abstract

A field experiment was conducted in 2005–06 on maize variety PMH-1 with dual inoculation of Azorhizobium and VAM (Glomus fasciculatum) along with application of formononetin. The seeds inoculated with Azorhizobium and VAM and treated with formononetin showed positive interactions for germination, percent mycorrhizal infection, N and P contents, total chlorophyll and other growth parameters as compared to control. Azorhizobium +VAM + formononetin treatment increased nitrogenase activity of treated plant roots. A 22.1 per cent increase in grain yield over control was observed by the dual inoculation and formononetin treatment.

8 of 11 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
