Forward To achieve the government's objective of food self-sufficiency, Kenya's farmers must increase food production and ensure its proper preservation in order to satisfy the rapidly increasing population. The On-Farm Grain Storage Project, sponsored by the Ministry of Agriculture, is introducing improved grain storage management technology to the small-scale farmers. One of the efforts of achieving this aim is through the reduction of losses to rodents, birds, moulds and insects. These losses, which could reach 25% or more, occur in farms from the time grain reaches maturity in the field until it is consumed. The project was initiated in 1983 using the regular agricultural extension services to disseminate the technologies to the farmers. The field extension workers are expected to accomplish this by working with individuals, and sometimes by organizing field days attended by large groups of farmers. Having only a minimum of training in extension communication skills, few reference materials, and practically no visual aids, some of the Agricultural Assistants have not been able to communicate the project's and other messages as effectively as the Ministry would like. The Ministry hopes, therefore, that through this extension communication manual, the effectiveness of the front- line extensions workers will be significantly increased. This manual will also be useful at the Institutes of Agriculture, which are responsible for training the future frontline agricultural extension workers. E. K. Kandie Director of Agriculture
