Smother crops are characterized by what primary trait?

Smother crops are characterized by what primary trait?

• A. They shade weeds effectively
• B. They require chemical herbicides
• C. They cannot be used with annual crops
• D. They are drought-sensitive

Answer: (D)

Smother crops are grown to form a rapid, dense canopy that covers the soil. That close canopy blocks sunlight from reaching weed seeds and young weeds, so they germinate less and have less opportunity to compete. The essential effect is light interception and aggressive early growth that outcompetes weeds, which is why shading ability is the defining trait of smother crops. While individual species may vary in drought tolerance, and they can be used with annual crops or alongside other practices, the primary characteristic driving their weed-suppressing role is their capacity to create that shading canopy.
