Afosu Sub - Station

The Afosu sub - station is located in the Birim North of the Eastern Region of Ghana. It was established in 1972 but research activities started in 1975. Afosu is considered as marginal area for cocoa production due to its mean rainfall and prolonged dry spells but suitable for replication of experiments under climatic and edaphic conditions different from that of Tafo. The station provides extension services supply hybrid seedlings to farmers who call to seek advice on cocoa, kola and coffee cultivation. A senior research scientist heads the station.

Bole Sub - Station

The sub - station which is situated in Bole in the Northern Region of Ghana was established in 1975 to originally focus on sheanut development but over the years, its mandate has been widened to include research on cashew. The vision of the station is to develop appropriate technologies that offer solutions farmers' problems in sheanut and cashew cultivation, to supply clonal planting materials and to offer technical advices to farmers to increase production. The station is managed by a research scientist.

Bunso Sub - Station
