It has become one of the major tools utilized by extension agents as instructional materials for agricultural educational purposes in major parts of the world. In Nigeria, agricultural programmes are packaged by extension agents in collaboration with some media houses and broadcast at certain times which may not be convenient to watch, understand, and later referred to. This study therefore assessed the effectiveness of video documentary as training tool for farmers in south-west Nigeria. Methodologically, the qualitative approach was adopted as farmers were trained with the aid of a video documentary as instructional material and were assessed before and after the trainings provided with structured interview guides to gather the data required. The findings showed that video documentaries are effective training tools that aid understanding and retention of information shared even after several weeks of the training. Conventional extension practice is enjoined to embrace video documentaries as instructional training tools to facilitate and enhance farmer’s agricultural learning.
