The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
The water requirement of a crop is the total volume of water needed to support vegetative and reproductive growth, covering evapotranspiration losses, metabolic needs, and any unavoidable application losses.
Step 2: Detailed Explanation:
Wheat is a winter season (rabi) crop grown across diverse agro-climatic zones in India.
The total water requirement of wheat ranges between $450\text{ mm and }650\text{ mm}$ (equivalent to $45 - 65\text{ cm}$).
This requirement is typically met through $4\text{ to }6$ carefully timed irrigations.
The critical stages for irrigation in wheat include:
1. Crown Root Initiation (CRI) - the most critical stage ($21 - 25$ days after sowing)
2. Tillering stage
3. Jointing stage
4. Flowering stage
5. Milk stage
6. Dough stage
Among the choices provided, $50 - 55\text{ cm}$ represents the standard average water requirement of the wheat crop to achieve optimal yield.
Step 3: Final Answer:
The water requirement of wheat is $50 - 55\text{ cm}$, which corresponds to Option (C).
