Question

Match LIST I with LIST II
\[ \begin{array}{|l|l|} \hline \textbf{LIST I} & \textbf{LIST II} \\ \hline A. \ \text{Infiltration opportunity time} & I. \ \text{Tree crops} \\ B. \ \text{Surface irrigation} & II. \ \text{Command area} \\ C. \ \text{Check basin irrigation} & III. \ \text{Time of ponding} \\ D. \ \text{Cropped area irrigated} & IV. \ \text{Gravity irrigation} \\ \hline \end{array} \]
Choose the correct answer from the options given below:

• A. A-I, B-II, C-IV, D-III
• B. A-II, B-I, C-IV, D-III
• C. A-III, B-IV, C-I, D-II
• D. A-III, B-IV, C-I, D-II

Hint:

Connect irrigation concepts: Surface methods are gravity-driven. Basins are good for trees. The time water sits on the surface is the infiltration opportunity time. The area a project can irrigate is its command area.

Answer 1

The Correct Option is C

Step 1: Match each irrigation term in LIST I with its closest association in LIST II.
- A. Infiltration opportunity time: This is the length of time that water is present on the soil surface, allowing it to infiltrate. It is directly related to the III. Time of ponding.
- B. Surface irrigation: This is a broad category of irrigation methods (including basin, border, furrow) where water is distributed over the soil surface by overland flow, primarily driven by gravity. It is a form of IV. Gravity irrigation.
- C. Check basin irrigation: This method involves creating small, level basins surrounded by bunds. It is particularly well-suited for irrigating orchards or I. Tree crops.
- D. Cropped area irrigated: The total area of crops irrigated by a canal system is related to the total area the system is designed to serve, which is known as the II. Command area.
Step 2: Compile the correct pairings.
- A \(\rightarrow\) III
- B \(\rightarrow\) IV
- C \(\rightarrow\) I
- D \(\rightarrow\) II
This combination corresponds to option (C).
