- Observation Soil K and Ca were below recommended values in cocoa farms.
- Association Available soil phosphorus was higher on unshaded control plots than beneath shade trees.
- Association Cocoa yield was higher around shade trees than on unshaded plots.
- Association Shade species yield differences versus control were not significant in the minor crop season.
- Association Cocoa yield under Cedrela odorata was significantly higher than on control plots.
- Association Cocoa yield under Khaya ivorensis was significantly higher than on control plots.
- Association Cocoa yield under Terminalia superba was significantly higher than on control plots.
- Association Cocoa yield under Milicia excelsa was significantly higher than on control plots.
- Recommendation The authors recommend particular shade tree species to maintain high cocoa yields in low input systems.
