The yields of two intercropped cocoa/kola plots at the Cocoa Research Institute of Nigeria, Ibadan, (W8/1 and C3/1), were compared with the yields of monoculture plots (N4/A and W1/2). It was found that 1.75 ha of monoculture plot gave the same crop yield (kg/ha) as 1.00 ha of mixed crop. The cocoa component started fruiting earlier than kola and also continued to yield annuall so there was no crop failure in any year.
