Abstract

The root-knot nematode, Meloidogyne incognita and the reniform nematode, Rotylenchulus reniformis caused significant reduction in plant growth of okra cv. Pusa Sawani. Consequently water absorption capability of roots was impaired. In concomitant infections the reduction in plant growth as well as in water absorption capability of roots was more pronounced. The reduction of plant growth in combined inoculations was, however, relatively less than the sum total of reductions caused by the same levels of the single species inoculations. In single as well as in combined inoculations the reduction in plant growth and in water absorption capability of roots was found directly proportional to the increasing inocula of both the nematodes. In co-habitation the nematodes were antagonistic to each other.
