Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R Assertion A: The border and check basin method of irrigation have vertical movement of water whereas furrow irrigation have only lateral movement in soil. Reason R: The Kostiakov's infiltration function can be used to determine infiltration characteristic of soil. 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 water movement:
• Border irrigation \(\rightarrow\) Mainly vertical infiltration
• Check basin irrigation \(\rightarrow\) Mainly vertical infiltration
• Furrow irrigation \(\rightarrow\) Predominantly lateral wetting Kostiakov infiltration equation: \[ \boxed{ Z = kt^a } \] where:
• \(Z\) = infiltration depth
• \(t\) = time

Answer 1

The Correct Option is B
