44.9. Case Studies and Examples

Try these first

1. 1.

   What is the formula to calculate ET using pan evaporation?

   Hint

   Recall the components involved in the calculation.

2. 2.

   Define what an irrigation scheduling chart includes.

   Hint

   Consider the main elements that affect irrigation management.

3. 3.

   What does Kc stand for in the irrigation context?

   • Crop Coefficient
   • Soil Coefficient
   • Pan Coefficient

   Hint

   Think of its purpose in irrigation calculations.

4. 4.

   True or False: Pan Evaporation is not related to irrigation scheduling.

   • True
   • False

   Hint

   Remember how ET correlates with irrigation decisions.

5. 5.

   If a farmer wants to irrigate tomato plants based on your ET calculation (3.57 mm/day), how would they adjust irrigation in a week with varying weather, including rainfall predictions?

   Hint

   Consider how weather conditions influence watering schedules.

6. 6.

   Analyze a field with a CWR of 150 mm. If rainfall yields 60 mm, and groundwater and soil contributions cover another 40 mm, calculate the irrigation requirement and suggest an efficient method for its application.

   Hint

   Keep in mind the need for efficient delivery using irrigation methods.
