This document distinguishes between ‘anchor’ cover crops (that are intercropped with a main crop such as maize) and ‘secondary’ cover crops (that don’t compete with the main crop because they have a short life cycle, and that can help cover the soil at the start of the growing season). The document also includes short summaries of five cover crops: jack bean, pigeon pea, lablab beans, cowpeas, and mung beans.
