Question

Consider the following statements:
1. The potential evapotranspiration is the same as the consumptive use for an irrigated crop.
2. Interception losses consist of only evaporation losses.
3. The potential evapotranspiration mainly depends upon characteristics of soil and vegetation.
4. The Lysimeter gives the potential evapotranspiration.

Which of these statements is/are correct ?

• A. 2 and 3 only
• B. 1 and 2 only
• C. 1 and 4 only
• D. All of the above

Answer 1

The correct option is B 1 and 2 only

• The potential evapotranspiration depends upon climatological factors rather than on characteristics of plant and soil. While actual evapotranspiration is largely affected by the characteristics of soil and vegetation.

• Lysimeter test is a field test so it gives the actual evapotranspiration.
