Considerations on the reintroduction of grass pea in China

Grass pea (Lathyrus sativus L.) is probably the most drought tolerant legume crop and it is also resistant to moderate salinity. In drought prone areas the plant is considered an insurance crop for subsistence farmers. During drought-triggered famines, grass pea can be the only food available and a lifesaver. In addition, grass pea is valuable for its abundant nutrients, especially protein and lysine. Historically, grass pea has been a daily food for millions in Asia and Africa, and is now reintroduced into popular use in different parts of the world as a fine green manure, forage, and food. For better and safer use of grass pea, there have been a number of efforts of different research groups from different disciplines.
