This study investigates how communication channels to exchange agricultural information were chosen.
Specifically, it identifies the communication channels used by farmers in Tanzania and determines the factors
influencing the choice of communication channels for exchanging agricultural information. The study employs a
meta-analysis review methodology in identifying, evaluating and interpreting studies relevant to the topic of
interest. The results indicate that radio, mobile phones, television, fellow farmers, agricultural extension agents
and newspapers were the commonly used communication channels for transferring agricultural information.
Moreover, the channels’ influence, availability, affordability, communication network coverage, and the
resources and facilities needed to use a particular communication channel were found to influence the
choice of channels. It is concluded that understanding the audience, the characteristics surrounding
messages and choosing appropriate communication channels are important for enhancing access to
agricultural information. It is recommended that agricultural information providers should understand the
factors surrounding communication channels before disseminating agricultural information.
