This paper analyses the influence of social-demographic features in accessing and using agricultural information services among small-scale crop farmers in Tanzania. The survey approach was adopted. The study involved 150 small-scale crop farmers from Rukwa region. A combination of qualitative and quantitative research methods was used. Data was systematically collected. Questionnaires were used to collect data supplemented by interview and observation. Chi-square analysis was used to determine the significant factors affecting access to and use of agricultural information services. The results were crosstabulated against social-demographic features of respondents. The findings show that social- demographic characteristics of respondents such as age, gender, education level and average income per year have an influence on agricultural information access and use. The study recommended that the existing agricultural information systems and services should be reviewed. A centralized agricultural database management system should be established to collect, organize, and disseminate agricultural information to small-scale crop farmers focusing on their social-demographic differences.
