Given that a particular crop requires about 20 cm depth of water at an interval of 40 days, and the base period is 400 days. Find the delta for the crop? Now using this delta find the duty of water for the crop?

Given that a particular crop requires about 20 cm depth of water at an interval of 40 days, and the base period is 400 days. Find the delta for the crop? Now using this delta find the duty of water for the crop? Correct Answer 200 cm, 1728 hectares/cumec

Given that base period is 400 days at an interval of 40 days. This number of waterings as = 400/40 = 10 Now delta = 10 x 20 = 200 cm. Now we have relation between delta and duty as – Delta = (864B)/D B = base period, D = duty 200 = (864 x 400)/D D = 864 x 2 = 1728 hectares/cumec.
