Rattlebox or rattle pod which is a common name of crotalaria ochroleuca, derived from the fact that the seeds become loose in the pod as they mature, and rattle when the pod is shaken (Bhatt et al., 2009). The crop is mainly used as a leafy vegetable in Kenya and Tanzania where the young shoots and leaves are harvested (Taylor and Francis, 2010). These are chopped, boiled and eaten with the staple foods including: maize, beans or sorghum (Chauvet, 2018). The dietary importance of the crop is for its principle source of beta-carotene, which is a precursor of vitamin A (Sahou, 2015).
