Q. The command area of a canal grows only one crop, i.e., wheat. The base period of wheat is 120 days and its total water requirement, Δ, is 40 cm. If the canal discharge is 2 m3/s, the area, in hectares, rounded off to the nearest integer, which could be irrigated (neglecting all losses) is
Solution:
Given, Base period (B) = 120 days
Delta (Δ) = 40 cm = 0.40 m
Discharge (Q) = 2 m3/sec
