Pigeon pea (Cajanus cajan) is a grain legume crop in the family Fabaceae. It is cultivated in the semi-arid tropics. In Kenya, pigeon pea is the third most widely grown pulse crop. Besides other regions, pigeon pea is largely cultivated in Ukambani and Coastal regions in large pieces of land. Both the green and the dry pulses are consumed locally or exported in other countries like Tanzania, Malawi etc. Therefore, pigeon peas can be eaten as vegetables (immature pods or the green pigeon pea) or as dried grains.
