Adoption of maize production technologies in Northern Tanzania

Adoption of maize production technologies in Northern Tanzania - Addis Ababa (Ethiopia) CIMMYT*EARO : 1999 - p. 371-374 - Printed
A survey of 126 farmers was conducted with an objective of evaluating adoption of maize research and extension in northern Tanzania in 1995. Factors affecting adoption of improved maize seed and fertilizer were analyzed using Heckman's procedure. About 91% of sample farmers used improved seed. Due to high adoption of maize seed, the impacts of most of the factors affecting adoption were not significant. About 80% sample farmers recycled improved maize seed for three to six years. The extension services should advise farmers on how to recycle composites and discourage them from recycling hybrids. Adoption studies in areas where seed recycling has replaced unimproved varieties should categorize farmers who recycle seeds more than three years as non-adopters. About 64% of the intermediate zone respondents applied chemical fertilizer, as compared to 44% in the lowland zone. The level of fertilizer applied was well below recommendation. No farm characteristic influenced intensity of fertilizer adoption. Other fertility management technologies were poorly followed, hence the need to increase extension efforts for fertilizer technologies.
