The cowpea (Vigna unguiculata) is an annual herbaceous legume from the genus Vigna. Due to its tolerance for sandy soil and low rainfall, it is an important crop in the semiarid regions across Africa and Asia. It requires very few inputs, as the plant’s root nodules are able to fix atmospheric nitrogen, making it a valuable crop for resource-poor farmers and well-suited to inter-cropping with other crops.

Black-eyed peas are cultivated in many regions across the globe, and are so-called for the small black ‘eye’ where the bean is adjoined to the pod within the shell. Despite the name, they are more similar to beans than peas and share many of the same culture requirements as other legumes.
