Question

Critical stages for irrigation in wheat are

• A. Crown Root Initiation (CRI) and Flowering
• B. Sprouting and Panicle initiation
• C. Early littering and Flowering
• D. Ripening and Maturity

Hint:

Wheat critical stages:
- Crown Root Initiation (CRI): 20-25 DAS.
- Flowering: Sensitive to moisture stress.
- Both stages require adequate moisture.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of critical stages for irrigation in wheat.

Step 2: Detailed Explanation:
The critical stages for irrigation in wheat are Crown Root Initiation (CRI) and Flowering (A).
CRI is the stage when the crown roots develop (about 20-25 days after sowing).
Flowering is the reproductive stage.
Both are sensitive to moisture stress.
Other options:
- Sprouting and Panicle initiation (B): Not for wheat (panicle initiation is for rice).
- Early littering (C): Not a standard term.
- Ripening and Maturity (D): Less sensitive to moisture stress.
Thus, CRI and flowering are critical stages.

Step 3: Final Answer:
Thus, critical stages for irrigation in wheat are CRI and Flowering, which corresponds to option (A).
