Question

Solidity is the maturity index for………

• A. Root vegetables
• B. Seed vegetables
• C. Leafy vegetables
• D. Cucurbits

Hint:

Think of a Cabbage. You don't look for color or sugar; you squeeze it to see if it's "solid." That's the harvest index!

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
In post-harvest technology, a "maturity index" is a physical or chemical sign that a crop is ready for harvest. "Solidity" refers to the density or compactness of the vegetable.

Step 2: Detailed Explanation:

• Leafy Vegetables (Option C): For head-forming leafy vegetables like Cabbage and Lettuce, solidity is the primary harvest index.

• Harvest Criteria: The farmer feels the head; if it is firm and "solid" to the touch, it indicates that the leaves are tightly packed and the vegetable has reached full development. A "hollow" or soft feel means it is immature.

• Other indices:
- Root vegetables: Size and days after planting.
- Seed vegetables (like peas): Tenderness (tenderometer reading).
- Cucurbits (like watermelon): Sound (thumping) or skin color change.

Step 3: Final Answer:
Solidity is specifically used as a maturity index for head-forming leafy vegetables.
