There is a large number of underutilized crops in Sri Lanka and also some farmers have lots of knowledge and experience on cultivation and use of these crops. However, no proper studies have been carried out about them and no books are available on them in the country yet. This is the first book of its kind. It contains several aspects of cultivation and use of underutilized crops and thus it will be useful for university students, researchers, agricultural officers, policy makers in national as well as international level.
