Delta for a Crop
Delta is defined as the depth of water required to produce a crop. It is expressed in cm or mm. Delta depends upon the duty and base period of the crop.
Given data:
Duty = 864 hectares/cumec
Base period = 120 days
Calculation:
1 hectare = 10,000 m²
So, 864 hectares/cumec = 864 x 10,000 m²/cumec
= 8,640,000 m²/cumec
We know that Duty = Delta x Area x K x 24 x 60 x 60 / Base period x 10^8
Where,
Area = Area under irrigation (m²)
K = Crop factor
24 = Conversion factor (hours to seconds)
60 = Conversion factor (minutes to seconds)
10^8 = Conversion factor (hectares to m²)
Let us assume the area under irrigation as 1 hectare.
So, Area = 10,000 m²
K is assumed as 1 for this calculation.
Now, substituting the given values in the above equation, we get:
864 x 10^4 = Delta x 10^4 x 24 x 60 x 60 / 120 x 10^8
Delta = 120 cm
Therefore, the delta for the given crop is 120 cm. Hence, option D is the correct answer.

Therefore, the delta for the given crop is 120 cm. Hence, option D is the correct answer.
