Question

How do weeds affect plant growth?​

Answer 1

Answer:

Weeds are unwanted plants that compete for nutrients and other factors with crop plants. As a result, they harm plants by interfering with their growth.

Explanation:

Weeds compete with the main plant for air, water, sunlight, and nutrients in the soil, depleting the main plant's resources. They're also useless to humans. As a result, they impede the plant's growth, necessitating its removal.

Some weed-control measures include:

1. Removal by hand.

2. Weedicide spraying

3. correct seed and soil preparation

4. Crop sowing at the right time, intercropping, and crop rotation

5. The use of pathogen-resistant varieties of crops.

6. Summer ploughing, which includes deep ploughing to eliminate weeds and plants.
