The extensive use of research, seed and extension farms for commercial production in order to augment limited budgets, and the scarcity of farm infrastructure (tractors, storage, irrigation), limit the land available for research and trials. Limited mobility and motivation of research and particularly extension staff can occur as a result of low salaries and benefits, and competing demands to undertake unrelated tasks. Many farmers lack access to high quality seed. The libraries of research, extension, and training institutions are outdated and lack most important agricultural scientific literature
