abstract
In Sub Saharan Africa, one of high potential nutritional crop is the Bambara groundnut. Popular and neglected legume, it is available in very low amount despite of being the richest seeds in lysine and methionine. To enhance the production of this crop and raise it as a strategic crop to fight hunger, the present work investigate in smallholders farms, the typology of systems of production of Bambara groundnuts in Adamawa Region of Cameroon. After 2 agricultural campaigns, storage facilities, morphotypes cultivated, storing method and protective tools to secure stored seeds were censed. Two bruchids (Coleoptera: Chrysomelidae): Callosobruchus subinnotatus (Bridwell) and Callobruchus maculatus (Fabricius), are major pests present on 10 of the 14 morphotypes of Bambara groundnuts sampled. To alleviate their damages, hazardous pesticides are currently used by producers, the possibility for developing some alternatives from local tools is discussed.
