I need to ask this question from Techniques of Water Distribution in the Farms in section Water Requirements of Crops of Irrigation Engineering

Answer 1

Correct option is (a) Border Flooding

For explanation: This type of method uses borders to divide the land into strips of with 10 to 20 meters, 100 to 400 meters in length each. Ridges are provided between borders so as to prevent overtopping during irrigation. Supply ditches run perpendicular to borders either on one side of the field to provide water for irrigation.
