In a context of prices and climate uncertainty, multi-purpose crops are a true asset for farmers. Pigeon pea (Cajanus cajan) is a legume crop that can be used for human and animal consumption, silkworm or stick lack production. It can also be used as shade crop, cover crop or windbreak. After establishment, pigeon pea also improves the soil by its extensive root system, nitrogen fixation by Rhizobium and the mulch provided by the fallen leaves. Pigeon pea can be produced sole, in rotation and/or association with the main cereal crops cultivated in Lao Uplands e.g. rice, maize or job’s tear.

In 2015, EFICAS project supported the use of pigeon pea in 7 villages.
