Abstract: Roots and soil were sampled for the presence of plant-parasitic nematodes from seven selected locations in North Central Nigeria noted for cashew production. Ten genera of plant-parasitic nematodes were found associated with cashew in North Central Nigeria. Meloidogyne sp., Helicotylenchus coffeae and Radopholus sp., were widespread in all the locations while Rotylenchulus reniformis was recorded only in Ochaja, Ayingba and Ejule. There were significant reduction in the height of cashew seedlings inoculated with root-knot nematodes, Meloidogyne incognita, in the nursery. Therefore, pre-planting sampling strategies should be taken to predict the impact of the nematode populations and enable preventive measures to be taken, most especially at the seedlings stage.
