The first irrigation in wheat is normally recommended at __________.

Correct option is B

The correct answer is (b) Crown root initiation stage

Explanation:

• The Crown Root Initiation (CRI) stage is the most critical stage for irrigation in wheat.
• It occurs approximately 21 days after sowing (DAS).
• At this stage, the transition from seminal roots to crown roots happens.
• Moisture deficiency at this time can lead to a significant reduction in grain yield.
• If only one irrigation is available, it should be provided at this stage.

• Wheat generally requires 4 to 6 irrigations depending on the soil type and weather.
• Other critical stages include Late Tillering, Late Jointing, Flowering, and Milk stage.

• Occurs around 40-45 days after sowing; irrigation here helps in increasing the number of tillers.

• Occurs around 80-85 days after sowing; crucial for pollination.
