Two-year trials were conducted in the year 2020 and 2021 at Moor Plantation, Ibadan, in the derived savannah of South-West, Nigeria to investigate the types, frequency, and population of plant-parasitic nematodes associated with kenaf under mono-cropping and kenaf-cowpea mixed cropping system. Soil samples were collected at random and nematodes extracted. Nematodes were identified based on their morphological patterns. Six nematode species were detected from the rhizosphere of kenaf under mono-cropping system. These were Meloidogyne incognita, Pratylenchus brachyurus, Helicotylenchus dihystera, Hoplolaimus pararobustus, Rotylenchulus reniformis, and Longidorus spp., while, two additional genera; Scutellonema bradys and Criconemella spp. were found under mixed cropping system in both years. Meloidogyne incognita had the highest population and frequency of occurrence in both cropping systems, while Longidorus spp. and Criconemella spp have the least under monoculture and mixed cropping system respectively. This study suggests that the population dynamics of plant-parasitic nematodes associated with kenaf could be dependent on the adopted cropping system.
