Abstract: Evaluation of the effects of different organic manures on root-gall nematode disease on African yam bean was conducted in a sandy loam soil naturally infested with a root-gall nematode, Meloidogyne incognita. The experiment was conducted in a randomized complete block design with four replications. African yam bean plant were treated with sawdust, municipal garbage, swine, compost, poultry and farmyard manures at 2.5 ton ha 1. Results showed that severe root galls occurred on plants treated with sawdust and rare galls on those treated with poultry and farmyard manures. Growth and yield characteristics of the plant were also affected by root-gall damage at the various organic manure treatments.
