Question

Given below are two statements:
Statement (I): Check basin method is suitable for irrigated crops which are sensitive to wet soil conditions around the stems of plants.
Statement (II): Check basin irrigation is the most common method of irrigation in India and in many other countries.

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:

To irrigate plants that are highly sensitive to stem moisture, always use the "ring basin" or "furrow" method, which keeps the main stem dry.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Check basin irrigation is a surface irrigation method where the field is divided into small, level plots surrounded by low bunds. These basins are then filled with water to a designated depth.

Step 3: Detailed Explanation:
1.

Statement (I): In the check basin method, water completely floods the basin area and stands around the stems of the plants.
For crops sensitive to wet stem conditions (e.g., citrus trees, papaya, and certain vegetables), this standing water can promote stem rot or collar rot.
Therefore, the check basin method is

unsuitable for water-sensitive plant stems (furrow or ring-basin methods are preferred). Statement (I) is incorrect.
2.

Statement (II): Because it is simple to construct, low-cost, and does not require complex equipment, the check basin method is the most widely used surface irrigation system for crops like paddy, wheat, and ragi in India and other developing countries. Statement (II) is correct.

Step 4: Final Answer:
The correct option is 4, which corresponds to Statement (I) is incorrect but Statement (II) is correct.
