This study examined agricultural marketing information usage among soybean farmers in Nigeria using data from randomly sampled 150 soybean farmers in Benue State. The soybean farmers get agricultural marketing information mainly through other soybean producers (83.33%), family (70.00%), neighbours (67.33%), farmer's cooperative organization (65.33%) and extension agents (62.67%). Other soybean producers (83.33%), family (81.33%), neighbours (80%), farmer cooperative society (80%), extension agents (66.67%) were highly evaluated as USEFUL by the farmers. Other soybean producers, cooperative society, off-farm employment, extension services and access to markets significantly influenced the probability of producers evaluating their agricultural marketing information as adequate. The greatest constraint to access to agricultural marketing information by soya bean farmers included inadequate access to extension services (22%), ineffective communication (20%), distance from other soya bean producers (16.67%), middlemen (16%), lack of capital (13.33%) and illiteracy (12%). Information sources and marketing information usefulness were not independent of one another among the respondents. Information sources and marketing information adequacy are not independent of one another among the respondents. More extension agents should be deployed to where the farmers are residing so as to reach a large number of the farmers and teach them on their areas of critical needs. Other methods of extension information dissemination should be used to transfer current, adequate and useful marketing information to the farmers. It should be ensured that any extension method being used to disseminate marketing information to the farmers is such that the farmers understand the message and marketing information being communicated to them.
