Abstract:This article investigates the impact of technical intervention on the adoption of a set of improved rice production technologies, as well as on productivity and profit for smallholders in rainfed lowland areas in Northern Ghana. The key finding is that productivity and profit are significantly enhanced when modern varieties (MVs) and chemical fertilizer are adopted, coupled with water control techniques. This is essentially the transfer of the Asian Green Revolution to sub‐Saharan Africa. Such transfer, however, is not truly successful unless information about the use of MVs and fertilizer is directly disseminated by extension activities.
