Referring to plants or crops that do not belong to the legume family, which includes beans and peas.
Corn is a nonleguminous crop that is widely grown for food and animal feed.
Nonleguminous → It is formed from "non-" (meaning not) and "leguminous" (from Latin "leguminosa" meaning pertaining to legumes). The word "nonleguminous" refers to plants that are not part of the legume family.
Think of 'not' ('non-') being used to describe plants that are 'pertaining to legumes' ('leguminous'). This helps you remember that nonleguminous means plants that are not legumes.
