The Agronomy Division is responsible for developing appropriate and cost-effective technologies which address farmers’ problems with respect to the early establishment and efficient management of young and mature cocoa, coffee, kola, shea and cashew plantations in order to realize the full economic potential of these crops. The Division also undertakes cartographic works and collects and manages all meteorological data for the Institute including its three substations at Bunso, Afosu and Bole.

Broad areas of investigation in the Division include plant propagation, determination of optimum plant density and spatial arrangement, suitable shade tree selection and density. Others are weed management, agro-forestry including inter-cropping with food and other crops, pruning and soil water management.

Current research activities include:

Cocoa
