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 Rice → Wheat → Cotton sequence is an ineffective crop rotation. These three crops are nutrient-depleting and fail to replenish soil nutrients. An effective rotation incorporates legumes for nitrogen fixation and soil fertility improvement, elements lacking in this sequence.
