Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The total available water for plant growth (TAW) is the water between field capacity and ultimate wilting point. Reason R: The maximum allowable deficit (MAD) is a part of total available water (TAW) and is usually considered as \(50%\) of TAW. In the light of the above statements, choose the most appropriate answer from the options given below:
• Both A and R are correct and R is the correct explanation of A
• Both A and R are correct but R is NOT the correct explanation of A
• A is correct but R is not correct
• A is not correct but R is correct

• A. Both A and R are correct and R is the correct explanation of A
• B. Both A and R are correct but R is NOT the correct explanation of A
• C. A is correct but R is not correct
• D. A is not correct but R is correct

Hint:

Important irrigation relation: \[ \boxed{ TAW = FC - PWP } \] where:
• \(FC\) = Field Capacity
• \(PWP\) = Permanent Wilting Point Also remember: \[ MAD \approx 50% \text{ of TAW} \] Memory Trick: \[ \boxed{\text{“Plants use water between FC and wilting”}} \]

Answer 1

The Correct Option is B
