37.1. Crop Water Requirement (WR)

Try these first

1. 1.

   What is Crop Water Requirement?

   Hint

   Think about the water needs throughout the crop's life.

2. 2.

   List two factors that affect water requirements.

   Hint

   Consider what influences how much water crops need.

3. 3.

   What does Crop Water Requirement (WR) refer to?

   • Total water need during growth
   • Water needed post-harvest
   • Annual rainfall equivalent

   Hint

   Remember the context of crops and their lifecycles.

4. 4.

   True or False: Soil texture does not affect Crop Water Requirement.

   • True
   • False

   Hint

   Consider how different soils manage water.

5. 5.

   Given the climatic data and soil moisture levels of a farm in India, propose an irrigation schedule that optimizes water use based on the WR of the selected crop. Consider factors such as rainfall, evaporation rates, and soil type.

   Hint

   Use the provided WR calculations and local agronomic practices to frame your irrigation plan.

6. 6.

   Evaluate the potential impact on Crop Water Requirement if a farmer switches from traditional flooded irrigation to drip irrigation for their paddy fields.

   Hint

   Think about how water distribution changes using drip systems.
