39.8. Delta for Different Crops (Empirical Values)

Try these first

1. 1.

   What does Delta refer to in irrigation?

   Hint

   Think about water needs of crops.

2. 2.

   Which crop generally requires more water, rice or wheat?

   Hint

   Recall the empirical values discussed.

3. 3.

   What unit is delta typically measured in?

   • Liters
   • Centimeters
   • Hectares

   Hint

   What do we use to describe depth in irrigation?

4. 4.

   True or False: Wheat has a higher delta requirement than rice.

   • True
   • False

   Hint

   Consider their irrigation needs.

5. 5.

   Your region's climate has changed, and now rice requires 10% more water than before. If the previous delta for rice was 118.5 cm, what is the new required delta?

   Hint

   Calculate an increase based on the percentage.

6. 6.

   You are uncertain about your sugarcane field’s viabiliy. If you can only supply a delta of 250 cm instead of 310.3 cm, what strategies could you adopt to ensure the crop thrives?

   Hint

   Think about managing water supply and crop requirements.
