Question

Which of the following is NOT true for mixed farming?

• A. It helps in maintaining soil fertility.
• B. It reduces soil erosion.
• C. It improves production level and give higher production than monoculture.
• D. It provides suitable habitat for birds.

Hint:

Mixed farming gives stability, manure recycling and habitat. It does not always beat monoculture on yield.

Answer 1

The Correct Option is C

Step 1: Understand the question:
Mixed farming means growing crops and rearing animals together on the same farm, or growing several crops together.
The question asks for the one statement that is NOT true. So three statements are benefits we accept, and one is a claim we cannot accept as a general rule.

Step 2: Check option (1):
In mixed farming, animal dung and crop residues go back into the field as manure.
Legume crops also add nitrogen to the soil. So soil fertility is maintained. Option (1) is TRUE.

Step 3: Check option (2):
A farm with many crops and fodder plants keeps the ground covered for more of the year.
Roots hold the soil and leaves break the force of rain. So erosion is reduced compared to bare single-crop fields. Option (2) is TRUE.

Step 4: Check option (3):
Mixed farming mainly gives stability and lower risk. If one crop fails, another still gives income.
It does not guarantee a higher yield than a well-managed monoculture, which is often planted to get the maximum output of one crop.
So the claim of 'higher production than monoculture' is not generally true. Option (3) is NOT TRUE.

Step 5: Check option (4):
Many plant types and trees on a mixed farm give food, shelter and nesting places to birds and insects.
A monoculture gives much less habitat. Option (4) is TRUE.

Final Answer:
Only option (3) is not a correct statement about mixed farming, so it is the answer. \[ \boxed{3} \]
