The study was conducted to find out about the information sourcing, organization and dissemination by agricultural extension workers in Adamawa state agricultural development programmes. The objectives were to identify the sources, organization and dissemination of information by extension workers in ADADP. The research instruments used were questionnaire and interview. A proportionate stratified sampling technique was used to obtain the sample for the study. Ninety-three (93) subjects were used for the study. Data collected were presented in frequency tables and percentages. Analysis and discussions were made to each table and figure. Findings of this study revealed that most extension workers in ADADP sourced different types of agricultural information, they however mostly source information on livestock production, crop production/ protection, application of inputs like fertilizers, pesticides and herbicides. Because most of the agricultural information sourced are in document form, they were organized alphabetically by subject and chronologically by date. The study also revealed the absence of qualified and trained staff to manage the agricultural information, as this is left in the hand of extension personnel. Agricultural information sourced were disseminated to the farmers mostly through direct contact and field demonstration in vernacular/native languages. The study concludes that Agricultural Extension Service (AES) was conceived to extend research based findings and information on agriculture to the farmers towards improving their agricultural produce and standard of living. This information gap between researches and advancement in technological process is filled by agricultural extension workers being the information disseminators to farmers. Based on the findings several recommendations were made which include agricultural extension workers should be encouraged to disseminate information to farmers using the dominate language in the state and through modern technologies like the Radio/Television Services, so that information can reach the farmers living in the remote areas easier and cheaper and at the appropriate time. The authority of Adamawa State Agricultural Development Programme should provide library infrastructure so that agricultural information sourced could be organized, stored and manage properly. A librarian should also be employed to manage and organize the information sourced properly so that having access to such sources can be easier and consequently save the time of the user. They Adamawa state agricultural development programme should improve agricultural extension services by removing all bottlenecks or challenges faced by extension workers in their effort to source and disseminate appropriate agricultural information to farmers.
