Abstract

Glasshouse and micro-plot experiments were conducted to find out the influence of different application methods of arbuscular mycorrhizal fungus (AMF) Glomus mosseae such as seed pelleting, AMF mixed with soil and as a layer under seed, AMF soil pelleting, and direct application of spores against root-knot nematode Meloidogyne incognita on black gram (Vigna mungo). In both experiments, application of G. mosseae to black gram plants suppressed M. incognita soil population by up to 14-49% under pot culture and 35-46% reduction over nematode alone treatments. Variations among different application methods of AMF were observed in terms of plant growth and suppression of the nematode population. Among the methods tested, AMF mixed with soil recorded least gall index (2.8 and 2.2 in pot culture and micro-plot, respectively) and nematode population, (290 and 280/200g soil in pot and micro plot condition, respectively).
