Some benefits of African walnut
•Nuts ▫Proved to cure male fertility problem
•Oil from nuts▫Used in formulation of wood varnish,
vulcanized oil for rubber and leather substitute.
•Leaves ▫used for the treatment of dysentery
(Ajaiyeoba and Fadare, 2006).

Production of African walnut•Nut planted under indigenous trees
deliberately spared on agricultural lands and plantations
•Starts fruiting 2 years
•Fruits July – Sept
•Processing is at household level

Fruits Cut open with knife or cutlass and nuts
removed
Gathering of fruits Women, children (&

Application of African walnut to Conservation Agriculture
•Conserve indigenous tree species. ▫Prevent felling
•Decay fruit mesocarp improves soil fertility.
•High litter fall that improve soil fertility. ▫enhance function of soil microbs.

Issues for Development of the
walnut
![Page 25: Cultivation of African walnut Tetracarpidium Conophorum Mull. (Arg) on agricultural plantation: an approach to CA in Nigeria. Folaranmi Babalola](https://reader033.vdocument.in/reader033/viewer/2022061206/5482094cb07959420c8b46b2/html5/thumbnails/25.jpg)
Issues for development
•Producers: Small scale farmers at the local level
•Industrial utilisation: Not fully developed.
▫…hampering full scale production and exploration of inherent potentials.
![Page 26: Cultivation of African walnut Tetracarpidium Conophorum Mull. (Arg) on agricultural plantation: an approach to CA in Nigeria. Folaranmi Babalola](https://reader033.vdocument.in/reader033/viewer/2022061206/5482094cb07959420c8b46b2/html5/thumbnails/26.jpg)
Issues for devt…
•Lack of adequate storage facilities
▫Consumed within 1-2 days after cook
•Inadequate transportation ▫deplorable rural road networks.

Food for thought
•Let us recognize more and incorporate Indigenous Knowledge to CA.
•“When a knowledgeable old person dies, a whole library disappears”.
