Question

Statement A: Drum seedling is a technique of DSR which is basically a type of dry seedling.
Statement B: It is invented by CRRI.

• A. Both are true
• B. Both are false
• C. A is true and B is false
• D. B is true and A is false

Hint:

The drum seeder requires well-puddled, smooth, wet soil to allow the seeds dropped from the perforated drum to establish their roots easily. Thus, it is strictly a Wet-DSR tool.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Direct Seeded Rice (DSR) is an alternative to traditional transplanting, where seeds are sown directly into the field under either wet or dry soil conditions.

Step 3: Detailed Explanation:
1. Statement A: The drum seeder is used for direct sowing of pre-germinated seeds in puddled, wet soil conditions (Wet DSR).
It is not a "dry seedling" technique, as dry DSR involves sowing dry seeds directly into unpuddled, moist soils. Thus, Statement A is false.
2. Statement B: The plastic drum seeder technology was pioneered and popularized internationally by the International Rice Research Institute (IRRI) and adapted locally in India (especially by TNAU), not originally invented by CRRI. Thus, Statement B is false.

Step 4: Final Answer:
The correct option is 2, which corresponds to Both are false.
