Other claims from this paper (4)

Intervention effect Dual inoculation increased root nodule number, dry weight and nitrogen content compared with Rhizobium alone.
Intervention effect Rhizobium inoculation did not significantly affect Glomus sporulation in the rhizosphere.
Intervention effect Glomus inoculation increased phosphorus content, dry weight and grain yield without statistical significance.
Intervention effect Dual inoculation significantly increased shoot dry weight and nitrogen content over either single inoculation.
