        <dc:description>The adoption of improved sorghum technologies by smallholder farmers is still low in Tanzania. Many farmers&#13;
fail to acquire quality inputs due to different underlying reasons. This article analyzes factors underlining the&#13;
adoption of improved technologies among sorghum farmers in Tanzania and evaluates profitability of grain&#13;
production. A total of 212 individual farmers were interviewed through structured questionnaires from nine&#13;
districts. Data were analyzed using descriptive statistics, probit regression model and gross margin analysis.&#13;
Results show that 39.2%, 26.5%, 16.9%, 8.4% and 7.2% of sorghum farmers adopted seeds of improved&#13;
varieties, insecticides, inorganic fertilizers, threshing machine and optimum seed rate, respectively. Probit&#13;
estimates indicated that age, sex, number of years in school, group membership, farm size, availability of free&#13;
seeds, seed accessibility, grain market accessibility and grain market price were the significant factors&#13;
influencing adoption of these technologies. Adopters obtained higher profitability (822,288 Tshs/ha) than&#13;
non-adopters (374,363 Tshs/ha) of improved varieties. Further policy actions are needed to improve determinants&#13;
of adoption, breeding technologies and accessibility of agricultural inputs to ensure benefits to farmers and the&#13;
sorghum sub-sector.</dc:description>
