300 cm is the Delta of Crop when its duty is 432 hectares/cumec on the field if the base of the crop is 150 days. It is the amount of water needed throughout the base period to raise a crop over a unit area. The standard units of measurement are cm or m. While the “total water depth needed for the crop to mature” or even the “total water depth needed by the crop for its base period (in cm)” are the two ways that the “delta” for each crop is determined.

Steps to Find the Delta for a Crop
The Delta for each crop is defined as either the “total water depth necessary for the crop to mature” or the “total water depth required by the crop over its base period (in cm)”. Duty of water is the relationship between the amount of water needed and the extent of irrigated land.
It mostly relies on how much water the crops need; for example, if a crop needs a lot of water, less land will need to be irrigated, which reduces the water need. Given below is the relationship between duty, delta, and base period.
- Duty: The amount of land watered with a unit volume of water delivered throughout the base time is known as the irrigational area. Typically, it is stated in hectare/cumec.
- Delta: It is the amount of water needed throughout the course of the base period to raise a crop over a unit area. The standard units of measurement are cm or m.
- Base period: A crop’s base period is when it receives its first watering at the time of sowing to when it receives its final watering just before harvest. Days are used to convey it.
Where,
- D= Duty in hectare/cumec.
- ∆ = Delta in meters.
- B = Base period of the crop in days.
Therefore, as per the formula:
Duty = 432 hectares/cumec and Base of the crop = 150 days.
Summary:
Find the Delta for a crop when its duty is 432 hectares/cumec on the field if the base of the crop is 150 days
The Delta of the crop will be 300cm. The delta for each crop is defined as either the “total water depth necessary for the crop to mature” or the “total water depth required by the crop over its base period (in cm)”. By dividing the “total quantity of water needed by a crop cultivated in a certain location” by the “area where it is grown,” the delta for each crop is determined.
