Abstract: Inoculation effect of single and dual vesicular arbuscular mycorrhizal (VAM) with Gigaspora rosea, Glomus intraradices + Gigaspora rosea and Glomus etunicatum + Glomus intraradices on the growth and nutrients uptake (NPK) on Medicago sativa were carried out. Yield in the response of shoot and root dry weight was significantly increased due to dual inoculation than single inoculation. The dry weight of dual inoculation in shoot was 10.61g and 12.64 g and in root was 3.11 and 3.68 g, respectively while the nitrogen, phosphorus and potassium uptake % was also more due to dual inoculations.
