However, it does contain some antinutritional elements, notable phytic acid and protease inhibitors, which reduce the nutritional value of the crop. 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 intercroppingwith other crops. In contrary to other leafy vegetables, cowpeas requires less maintenance. Nigeria has reached a major food security milestone with the commercial release of insect-resistant cowpea — its first genetically modified (GM) food crop. , Compared to most other important crops, little is known about the domestication, dispersal, and cultivation history of the cowpea. , The cowpea has often been referred to as "poor man's meat" due to the high levels of protein found in the seeds and leaves.
