Assertion (A) Analysis: Crop Suitability in Dry Areas

Statement (A) suggests that short duration crops and those with deep root systems are suitable for dry areas. This is correct because:

• Short duration crops can complete their life cycle before the severe dry period fully sets in, requiring less water overall.
• Deep root systems allow plants to access water reserves deeper in the soil profile, which is crucial when surface moisture is scarce.

Reason (R) Analysis: Crop Efficiency Comparison

Statement (R) claims that safflower and chickpea are more efficient than rainfed wheat. This is generally true:

• Safflower and chickpea are known for their drought tolerance. They often have mechanisms, like deep root penetration and efficient water use, that make them perform better than wheat under limited rainfall conditions.
• Rainfed wheat can be more susceptible to yield loss during dry spells compared to these other crops.

Evaluating the Relationship

Reason (R) provides specific examples (safflower, chickpea) of crops that exhibit characteristics beneficial in dry areas. These crops are indeed more efficient under water-scarcity than rainfed wheat. Therefore, the efficiency of these specific crops validates the general principle stated in Assertion (A) regarding suitable crop types for dry regions.

Conclusion

Both Assertion (A) and Reason (R) are factually correct statements. Reason (R) supports and explains Assertion (A) by providing examples of crops that embody the traits mentioned in (A) and are proven efficient in dry conditions.

Therefore, both (A) and (R) are correct, and (R) is the correct explanation of (A).
