asked Aug 25, 2023 in Irrigation Engineering by Carter (75.2k points)

Duty of wells expressed in hectares the well can irrigate to bring a crop to maturity because of ___________

(a) well irrigation is a minor scheme

(b) well water is lifted immediately and cannot be expressed in ha/m^3/sec

(c) well is situated in the middle of the commanded area

(d) wells are owned by cultivators and so the source of supply is a private one

I got this question during an online interview.

The correct answer is (b) well water is lifted immediately and cannot be expressed in ha/m^3/sec

To explain I would say: In well irrigation water is lifted intermittently. The duty of a well is the area of land in hectares the well can irrigate annually and fully to bring a crop to maturity. It cannot be expressed in hectares/m^3/sec for a base period of a crop.
