The experiment was performed in a natural infested area with a mixed population of Pratylenchus coffeae and Scutellonema bradys , in Quebr angulo county (Alagoas state, Brazil) in a randomized block design with five treatments and five replicates. The sources of organic matter used as soil amendments were: coconut husk powder, castor bean cake, cattle manure and chicken manure. Non amended soil was used as a control. Nine months after planting, the tubers were harvested. No statistical differences were found among disease incidence, yam production and nematode population densities in the soil. However, the application of chicken manure reduced P. coffeae population in tubers.  aDioscorea  aDoença  aInhame  aMatéria Orgânica  aNematoide  aPodridão Seca  aPratylenchus Coffeae  aScutellonema Bradys  aNematode management  aYam1 aMUNIZ, M. de F.
