Step 1: Understanding the Concept:
Groundnut (Arachis hypogaea) is a unique oilseed crop where pod development occurs underground.
This underground fruiting habit (geocarpy) requires specific soil and environmental conditions.
Step 2: Detailed Explanation:
Let us analyze each statement:
- Statement I: Sandy and loamy soils are most suitable for groundnut.
This is correct. After fertilization, the flower stalk elongates downwards to form a "peg."
This peg must penetrate the soil surface to develop into a pod.
Loose, sandy, or loamy soils are well-drained and friable, which allows the peg to penetrate easily and provides a favorable physical environment for pod development.
Clay soils can bake hard, restricting peg penetration and making harvesting difficult.
- Statement II: Groundnut yield is higher during the rabi (winter) season than the kharif (monsoon) season.
This is correct. Rabi groundnut crops are grown under irrigation, allowing for precise water management.
The cool, dry winter weather reduces the incidence of pests, diseases, and weeds compared to the hot, humid kharif season.
Additionally, the clear, sunny days of the winter months provide abundant solar radiation for efficient photosynthesis.
Therefore, both statements are correct.
Step 3: Final Answer:
Both Statement I and Statement II are correct, corresponding to Option (A).
