Pick up the incorrect statement from the following: A. In free flooding irrigation, water is admitted at one corner of a field and is allowed to spread over the entire area B. In check method of irrigation, the field is divided into smaller compartments and water is admitted to each in turn C. In furrow irrigation water is admitted between the rows of plants in the field D. None of these

The correct answer is: A. In free flooding irrigation, water is admitted at one corner of a field and is allowed to spread over the entire area.

Free flooding irrigation is a method of irrigation in which water is applied to the soil surface without any control over the rate or direction of flow. This can lead to waterlogging and erosion, and it is not an efficient method of irrigation.

Check method of irrigation is a method of irrigation in which the field is divided into smaller compartments called checks. Water is admitted to each check in turn, and the flow of water is controlled by a series of gates. This method of irrigation is more efficient than free flooding irrigation, and it helps to prevent waterlogging and erosion.

Furrow irrigation is a method of irrigation in which water is applied to the soil surface between the rows of plants. The water flows in the furrows and is absorbed by the roots of the plants. This method of irrigation is efficient and it helps to prevent waterlogging and erosion.

Therefore, the incorrect statement is: A. In free flooding irrigation, water is admitted at one corner of a field and is allowed to spread over the entire area.
