Question

In which method of rice sowing transplanting of young seedlings, usually 8-12 days old, is done?

• A. Direct seeded rice
• B. Aerobic rice
• C. Conventional rice cultivation
• D. System of rice intensification

Hint:

SRI mantra: "Young seedlings, single plant, wide spacing, and alternating wet/dry soil." It helps in saving water and seeds while increasing yield.

Answer 1

The Correct Option is D

Step 1: Understanding the Question:
The question asks about a specific rice cultivation method where very young seedlings (8-12 days old) are transplanted, which is much earlier than traditional methods.

Step 2: Detailed Explanation:

• Conventional rice cultivation (C) usually involves transplanting seedlings that are 25-30 days old.

• The System of Rice Intensification (SRI) is an agroecological methodology for increasing the productivity of irrigated rice by changing the management of plants, soil, water, and nutrients.

• A core principle of SRI is the transplanting of very young seedlings, typically when they have only two leaves, usually at 8-12 days of age.

• This early transplanting preserves the plant's inherent potential for tillering and root development, which is often curtailed if the plant stays too long in the nursery.

• SRI also emphasizes wide spacing (single seedlings per hill) and keeping the soil moist but not continuously flooded.

Step 3: Final Answer: The method is the System of Rice Intensification (SRI).
