Step-by-step explanation:
The term for a low cover crop grown in the same field and at the same time with a taller crop is undercrop. An undercrop is a secondary crop that grows beneath the taller or main crop. It helps to reduce soil erosion, suppresses weed growth, enhances soil fertility, and provides additional yield.
For example, in a field of corn, a common undercrop could be a low-growing legume such as clover. The clover would grow beneath the corn, helping to improve soil health and nitrogen levels.
