Q1: During a particular stage of the growth of a crop, consumptive use of water is 2.8 mm/day, and the PWP is 13.6 mm in terms of depth and 17% as a percentage. If the base period of the crop is 120 days, determine delta (A) when the amount of water available in the soil is: (i) 25%, (ii) 50% (iii) 75%, and (iv) 0% of the maximum depth of available water in the root zone. Assume irrigation efficiency to be 65%.
