Solution
Weeds affect the growth of crop plants in the following ways:
- They compete with the crop plant for nutrients, water, space, and light, depriving the crop plants of essential nutrients.
- They spread crop pests by acting as hosts to insects and other microorganisms.
- Some produce toxic substances that harm the growth of crop plants.
- Some weeds get mixed up with crops during harvesting and lead to poor quality of crop production.
