Interaction of Arbuscular Mycorrhizal Fungus, Glomus fasciculatum and Root-Knot Nematode on Growth and Phosphorus Uptake of Tobacco (Nicotiana tabacum L.)

The interaction of arbuscular mycorrhizal fungus, Glomus fasciculatum with root knot nematodes Meloidogyne incognita and Meloidogyne javanica and their effect on the growth, yield and phosphorous nutrition was studied under pot culture besides the ability to mitigate damage caused by either of the two nematodes on tobacco. Inoculation with G. fasciculatum significantly reduced nematode population, number of galls and root-knot index besides increasing the growth, plant biomass, phosphorous uptake and yield of tobacco compared to plants inoculated with root-knot nematode alone.
