9 pages., Cassava (Manihot esculenta) is an important regional food source, providing food and income to over 30 million farmers, processors, and traders in Nigeria. Extension programs support awareness and interest in new technologies; they facilitate the adoption and adaptation of new approaches to crop production, post-harvest processing, and marketing. Extension can be understood as an intermediary or catalyst in the dissemination of information to rural farmers. This study analyzed the effect of cassava farmers’ exposure to extension on a broad measure of cassava technology adoption, while considering the influence of some individual and farm characteristics as control variables. Data were obtained from personal interviews with sample of 952 households conducted in southern Nigeria. Results show a relationship between extension exposure and technology adoption. Farmer-to-farmer interaction played the greatest role in diffusion of the technologies. Interactions with extension agents were low, suggesting that adoption of improved technologies could be enhanced by improved regular contact with extension information. The results underscore the importance of farmer-to-farmer interaction processes that often overshadow extension assistance in supporting and guiding the use of production technology. The conclusions consider some implications for 21st century extension.
15 pages, In spite of several strategies implemented to improve sorghum production in Ghana, average grain yield in farmers’ fields remains low and far below the estimated potential. The development of effective strategies requires continuous, in-depth understanding of production constraints as well as farmer preferences for crop traits. To this end, a participatory rural appraisal using focus group discussions, interviews with semi-structured questionnaires and preference ranking was carried out among 122 smallholder sorghum farmers in the Upper East Region of Ghana. Majority (91%) of respondents were engaged in farming with more than half of their farm sizes allocated to sorghum cultivation. Drought, high cost of farm inputs and declining soil fertility were the top three constraints. Almost 42% of farmers described their soils as low in fertility. The most preferred traits by farmers were drought tolerance, high grain yield, earliness, grain quality as well as low fertilizer requirement. A better understanding of the perceptions of farmers and factors that limit the adoption of improved technology is important to guide policy towards the design of effective crop improvement and extension programmes. The study highlights the importance of breeding sorghum varieties with traits preferred by smallholder farmers that will lead to increased adoption of improved technology.
