Effect of individual and concomitant inoculation with Meloidogyne incognita and Rotylenchulus reniformis on the growth of black gram (Vigna mungo)

Relationships between the different population densities of Meloidogyne incognita and Rotylenchulus reniformis, individually and concomitantly alongwith growth of black gram (Vigna mungo) were studied under pot culture conditions. Both the species caused significant growth reduction at the level of one infective individual per cc of soil. In concomitant inoculations the extent of growth reduction was relatively less than individual effects. The fresh shoot weight was more sensitive to nematode injury than shoot length.
