Given data:
Delta (Δ) = 0.864 m
Base period (P) = 130 days
Duty of the crop is defined as the area of land (in hectares) that can be irrigated by 1 cumec of water during the base period.
Duty (D) = Area / Time / Discharge
where,
Area = Delta x Base period
Time = 24 hours x 60 minutes/hour x 60 seconds/minute
Discharge = 1 cumec
Substituting the given values, we get:
Area = 0.864 m x 130 days = 112.32 hectares
Time = 24 x 60 x 60 = 86400 seconds
Discharge = 1 cumec
Duty (D) = 112.32 / 86400 / 1 = 0.0013 hectares/cumec
Therefore, the duty of the crop is 0.0013 hectares/cumec, which is equivalent to 1.3 hectares/cumec (multiplying by 1000).
Hence, the correct option is (b) 1300.

Duty: It is the number of hectares of land irrigated for full growth of a given crop by a supply of 1 cumec of water continuously during the entire base period of that crop.
Delta: The total water depth required by a crop to attain its full maturity in its base period.
Base Period: The time period that elapsed for the instant of the showing of crop to the instant of its harvesting is called base period or crop period.
The relation between Duty in hectares/cumec (D), Delta in meter (Δ) and Base period in days (B) is given as:
Calculation:
Given data,
B = 130 days
Δ = 0.864 m
Hence, the delta for a crop
D = 1300 hectares/cumec
