Determinants of Adoption of Early Maturing Maize Varieties in Nzega District, Tabora Region

Nzega is the districts located in semi-arid areas of Tanzania where drought is a limiting factor. In the district farmers are advised to use early maturing maize varieties (EMMV). The adoption of EMMV in Nzega District is still low. Increase in use of EMMV is possible if factors which influence adoption are addressed. The study aims at identifying challenges facing efforts of promotion adoption of EMMV. The paper identifies determinants of adoption and level of adoption of EMMV. The paper uses data collected from a total of 150 maize farmers consisting of adopters and non-adopters. Multistage random sampling technique was used to select maize farmers from 10 villages. Data were collected using a structured questionnaire. Cragg?s double hurdle model was used in determining factors affecting adoption decision and the level of adoption. Results show that extension services, education level and size of the farm owned by the farmer, farmers income and distance to the nearest market were significant in affecting adoption decision and the level of adoption. Therefore, the adoption of EMMV can be attributed to institutional and socio-economic factors. The Government should put more effort in improving extension services, markets and provision of input subsidies for maize farmers.
