Extension for Agroforestry Technology Adoption: Mixed Intercropping of Crotalaria (Crotalaria grahamiana) and Maize (Zea mays L.) in Kabale District, Uganda

摘要

Understanding the factors that influencing farmer’s adoption of improved technologies is critical to success of implementing agroforestry development programs. This study, investigates the adoption of mixed inter-cropping an agroforestry tree species, crotalaria (Crotalaria grahamiana) and maize (Zea mays L.) in Kabale district, Uganda. The factors influencing the adoption of Crotalaria grahamiana in terms of farmer’s age, productive labourforce, extension contact, income sources, gender and other socio-economic variables were examined. Results from the maximum likelihood estimation of a logistic regression model suggest that the factors that influenced adoption were age of the household head, education level, extension contact, family labourforce and gender (all with significantly different coefficients from 0-10%). The other factors hypothesised to influence adoption did not have significant coefficients and, therefore, did not explain adoption decisions. They included sources of income, credit and farmer group membership. At the policy level, improving the quality of the extension systems is of paramount importance in Uganda.
