Correct option is D
Correct Answer: D. 50 kg/ha
- In transplanted rice, seeds are first sown in a nursery and then seedlings are transplanted to the main field.
- For raising enough healthy seedlings to transplant one hectare, a seed rate of about 50 kg/ha is recommended.
- This higher seed rate ensures:
- Adequate seedling population
- Proper gap filling
- Uniform crop establishment in the main field
Information booster:
- Transplanting is the most common method of rice cultivation in irrigated conditions.
- Seedlings are usually transplanted at 20–25 days (short duration) or 25–30 days (medium/long duration).
- Nursery area required is about 800–1000 m² per hectare of main field.
- Lower seed rate is used in direct-seeded rice compared to transplanted rice.
Why other options are incorrect:
- A. 10 kg/ha- Too low to raise sufficient seedlings for transplanting.
- B. 20 kg/ha- Used in some direct-seeded rice systems, not transplanted rice.
- C. 30 kg/ha- Still insufficient for nursery raising for one hectare of transplanted rice.
