21.3.4. Crop Coefficient (k)

Try these first

1. 1.

   What does the crop coefficient (k) influence?

   Hint

   Consider how crops interact with water.

2. 2.

   Why is it important to know the k value?

   Hint

   Think about the impacts of under or over watering.

3. 3.

   What is crop coefficient (k)?

   • A type of irrigation technique
   • A measure of water needed by crops
   • A type of crop variety

   Hint

   Think about how crops relate to their water needs.

4. 4.

   True or False: The value of k does not vary with different crop types.

   • True
   • False

   Hint

   Recall the differences in crops discussed earlier.

5. 5.

   Imagine you're an irrigation manager for a mixed-crop farm. How would you determine the k values for your crops using FAO resources? Outline the steps.

   Hint

   Think about how seasonality may affect crop growth.

6. 6.

   Evaluate the impact of using a flat k value across different crop types. What discrepancies might arise?

   Hint

   Consider the efficiency of resource usage.
