Question

The DAPOG method of raising rice nurseries was introduced in India from:

• A. Philippians
• B. Taiwan
• C. Japan
• D. China

Hint:

Dapog seedlings are ready for transplanting at a very young age (12-14 days).
They do not require soil during the nursery stage, making this method ideal when land or soil is limited.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
The Dapog method is an intensive, soil-less method of raising rice (Oryza sativa) seedlings in a nursery bed without direct contact with soil.
This method saves space and water, and significantly reduces the age of seedlings at transplanting.

Step 2: Detailed Explanation:
The Dapog method originated in the Philippines (often spelled "Philippians" as a typographical error in Indian examinations) and was introduced to India through the International Rice Research Institute (IRRI).
In this method:
- Seedlings are raised on an impermeable surface, such as a concrete floor, plastic sheets, or banana leaves.
- Pre-germinated seeds are sown thickly over this surface and kept moist by frequent watering.
- Because the roots cannot penetrate the underlying layer, they form a dense, cohesive mat of seedlings.
- The seedlings are ready for transplanting within only \( 12 - 14 \) days, which is much faster than the \( 25 - 30 \) days required in conventional wet or dry nursery beds.
- The seedling mat can be rolled up like a carpet, transported easily to the main field, and separated into small clumps for transplanting.

Step 3: Final Answer:
The DAPOG method of raising rice nurseries was introduced from the Philippines.
