Annex 3. Extension The project has been integrated into the Training and Visit system of extension. Agricultural Assistants, the front-line extension workers, pay fortnightly visits to participating farmers and also carry the project's messages to all forty-eight or more farmers on each AA's scheduled tour of duty. Within the Nyanza and Western Provinces more than 1,000 front-line workers have received orien- tation training in the practices recommended by the project. The project has promoted the use of field days whereby groups of farmers are invited to attend discussions of timely topics. These field days have proved a most effective use of the AA's time and talents. 4. Training The project has provided training in grain storage management, primarily for Agricultural Officers, Assistant Agricultural Officers, and Agricultural Assistants. Some of the highly specialized training for senior officers has been in formal courses overseas-in the UK and the USA. However, most of the training has been done in specially designed, in-country short courses. As well as this training for extension staff, there have been awareness-raising courses for location chiefs and members of the provincial and district administrations. To support this training, the project has produced and distributed a wide variety of printed and audio-visual materials related to the messages the project wishes to spread as widely as possible among the farmers of Kenya-and among those who are helping farmers to increase their productivity. This manual is an example of such training material. IMPLEMENTATION In 1990, after successfully introducing the project's grain storage management recommendations to farmers in Western Kenya, a national crop post-harvest management programme was imple- mented by Kenya's Ministry of Agriculture.
