  • B. Delta
  • C. Base period
  • D. Crop period
Correct Answer: Option A - Duty–The duty of water is the relationship between the volume of water and the area of the crop it matures. Or It is defined as the area irrigated cumec of discharge running for base period B. The duty is generally represented by 'D' Delta–It is the total depth of water required by a crop during the entire base period and is represented by the symbol ''. Base period–The number of day between time of first watering to the time of last watering is called as the base period 'B'.
