Question

Which of the following statements is NOT correct about the weeds?

• A. Weeds compete with crops for space
• B. Weeds compete with crops for light
• C. Weeds compete with crops for nutrients
• D. Weeds have no effect on the yield and quality of crops

Answer 1

The Correct Option is D

The correct answer is (D) Weeds have no effect on the yield and quality of crops.

Let’s break down the statements:

(A) Weeds compete with crops for space: This is correct. Weeds grow alongside crops and take up space that could otherwise be used by the crops.

(B) Weeds compete with crops for light: This is correct. Weeds often grow taller or spread in a way that blocks sunlight from reaching the crops, affecting their growth.

(C) Weeds compete with crops for nutrients: This is correct. Weeds absorb nutrients from the soil, which could otherwise be available for crops, potentially reducing crop growth.

(D) Weeds have no effect on the yield and quality of crops: This is incorrect. Weeds negatively affect both the yield and quality of crops by competing for space, light, water, and nutrients, and they can also harbor pests and diseases.

Thus, (D) is the incorrect statement, as weeds do affect both the yield and quality of crops.

 

Answer 2

Weeds compete with crops for resources like space, light, and nutrients, often leading to a reduction in crop yield and quality. The statement that weeds have no effect on crop yield and quality is incorrect.
