The frequency with which water is to be applied based on the need of the crop and the nature of the soil is known as-

  • A.Irrigation Scheduling
  • B.Water Budgeting
  • C.Irrigation requirement
  • D.Runoff Frequency

Answer: A

It is Irrigation Scheduling.

Irrigation scheduling decides when to irrigate and how much water to apply. The frequency of irrigation depends on the crop's water need at each growth stage and on the soil's capacity to hold water, so deciding the frequency on these grounds is the essence of scheduling.

Water budgeting is the accounting of water inflows and outflows for an area. Irrigation requirement is the quantity of water needed, not its timing. Runoff frequency concerns surface flow, not water applied to crops.
