In an agricultural area, the porosity and field capacity of the soil are measured as 46% and 39%, respectively. For a certain crop the permanent wilting point is 11% and the depth of the root zone is 1.2 m. The consumptive use is 16 mm/day. If the irrigation efficiency is Reg.No/100%, solve for the frequency of irrigation such that the moisture content does not fall below 50% of the maximum available water.
