Given that, a particular irrigation field has C.C.A as 200 hectares, out which 150 hectares of land is cultivated for rabi season and 100 hectares of land is cultivated for kharif season. What is the intensity of irrigation for each season?

(a) 50%, 100%

(b) 120%, 60%

(d) 150%, 75%

This question was addressed to me by my college director while I was bunking the class.

This intriguing question comes from Water Requirements topic in portion Water Requirements of Crops of Irrigation Engineering

Answer 1

Right option is (c) 75%, 50%

Best explanation: For rabi season:

Intensity of irrigation = (150/200) x 100

= 15 x 5

= 75%

For kharif season:

Intensity of irrigation = (100/200) x 100

= 0.5 x 100

= 50%.
