32. Assertion: (A): Rotation of crops helps in pest control management
Reason: (R): Rotation of crops improve soil fertility
Both A and R are correct and R explain A
Both A and R are correct but R does not explain A
A is true but R is false
A is false but R is true
Correct Answer :
Both A and R are correct but R does not explain A
Solution
- Assertion (A): Rotation of crops helps in pest control management. This is correct because changing crops disrupts the life cycle of pests specific to a particular crop.
- Reason (R): Rotation of crops improves soil fertility. This is also correct because growing different crops replenishes soil nutrients, especially if nitrogen-fixing crops are included.
However, the reason (R) does not explain the assertion (A) because improved soil fertility is unrelated to pest control.
