Question:

How many months after planting the ginger crop is ready for harvesting ?

Show Hint

Ginger maturity:
Green ginger (table use) $\rightarrow$ $5 - 6$ months.
Dry ginger (spice/processing) $\rightarrow$ $7 - 9$ months.
Maturity is indicated by the yellowing and drying of the foliage.

The Correct Option is D

Solution and Explanation

Step 1: Understanding the Concept:
Ginger (Zingiber officinale) is a herbaceous perennial grown as an annual crop for its aromatic rhizomes.
The harvesting time depends on the intended use of the rhizomes (e.g., green ginger, dry ginger, or seed ginger).

Step 2: Detailed Explanation:

Under standard tropical and subtropical conditions, ginger requires a warm, humid climate to mature.
The crop is ready for harvest when the leaves turn yellow and dry out completely, which typically occurs 7 to 9 months after planting.
This developmental timeline varies slightly based on the market requirements:
1. Green Ginger: Harvested slightly earlier ($5\text{ to }6\text{ months}$ after planting) when the rhizomes are tender and low in fiber.
2. Dry Ginger (Sonth): Harvested at full maturity ($8\text{ to }9\text{ months}$ after planting) when the fiber and volatile oil content are at their peak.
3. Seed Ginger: Harvested at full maturity, typically around 9 months.
Among the given choices, the range of $7 - 9$ months matches the standard maturity period for a dry ginger crop.

Step 3: Final Answer:

The ginger crop is ready for harvesting $7 - 9$ months after planting, which corresponds to Option (D).
