Question

The crop sequence, which cannot serve any useful purpose in crop rotation is

• A. Wheat → Jowar → Gram
• B. Rice → Gram →Rice
• C. Cotton → Wheat → Gram
• D. Rice → Wheat → Cotton

Hint:

In crop rotation, include nitrogen-fixing legumes or fallow periods to restore soil fertility and prevent nutrient depletion

Answer 1

The Correct Option is D

The sequence Rice → Wheat → Cotton does not effectively serve the purpose of crop rotation because all three crops are high nutrient-demanding and do not contribute to replenishing soil nutrients. An effective crop rotation includes crops like legumes to fix nitrogen and improve soil fertility, which is missing in this sequence.
