Question

Given below are two statements:
Statement (I): Water storage efficiency becomes important when water supplies are limited or when excessive time is required to secure adequate penetration of water into the soil.
Statement (II): Water application efficiency decreases as the amount of water applied during each irrigation increases.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

Think about what happens to extra water once the root zone is already at field capacity.

Answer 1

The Correct Option is A

Step 1: Think of the root zone as a bucket that needs filling to field capacity. Storage efficiency is only a concern when water is scarce or slow to soak in, because otherwise you can just keep irrigating until the bucket fills; this matches Statement (I).
Step 2: Now think about what happens once the bucket is already full: any extra water poured in beyond that point drains past the root zone or runs off the surface instead of being usefully stored, so the fraction of applied water that is usefully stored (the application efficiency) must go down as more water is applied. This confirms Statement (II).
\[\boxed{\text{Both Statement (I) and Statement (II) are correct}}\]
