A pot experiment was conducted to study the tolerance induced by vesicular arbuscular mycorrhizal fungi (VAM) and effective Microorganisms (EM) in chick pea (Cicer arietinum L.) against allelopathic stress caused by aqueous leaf extract of Syzygium cumini (L.) Skeels. The adverse impact due to aqueous leaf extract on plant vegetative and reproductive growth and shoot nitrogen contenct was significantly reduced by the application of EM and VAM. Co-inouclation of EM and VAM was found more effective that inoculation with either alone. However, reduction in shoot phosphorus content due to allelopathic stress could only be compensated by VAM inoculation alone. VAM colonization was stimulated by EM application.
