Production and marketing of yams in the forest/savanna transition zone of Ghana.

A three-month field study was conducted to identify the constraints to the production and marketing of yams in the forest/savanna transition zone of Ghana, particularly the districts of Techiman, Nkoranza and Kintampo. The objective was to identify research priorities for the Crops Research Institute, Kumasi and other institutions in Ghana. Data collection methods included analysis of secondary data, Rapid Rural Appraisal (RRA), visits to yam farms, Participatory Rural Appraisal (PRA) workshops with farmers in four separate settlements using a checklist as a guide, detailed farm level case studies and workshops with extensionists and researchers. The data collected were analysed through the construction of a problem-causal tree to illustrate the key problem areas and linkages. The main problems identified as affecting the productivity of yams are due to: low or dealing soil fertility which is related to other problems, such as limited access to credit and shifting of production to more fertile b

ut inaccessible areas with negative implications for storage, transportation and marketing, high incidence of pests and diseases, insufficient soil moisture at critical periods, high incidence of weeds, inadequate extension services, and an inefficient marketing system. Key research recommendations were made for the improvements of yams through breeding and varietal selection, agronomy and soil fertility, pests and diseases, postharvest and processing as well as marketing and socioeconomics. Since the problems identified included development ones, solutions which are mostly policy-related, were proposed. Despite the constraints identified, the study concludes that yams have great potential both as an export crop and for home consumption.
