    The consumptive use of water for a crop during a particular stage of ...
    Given Data:
    - Consumptive use of water for a crop during a particular stage of growth: 2.0 mm/day
    - Maximum depth of available water in the root zone: 60 mm

    To find:
    - Frequency of irrigation (in days) when the available water is 50% of the maximum available water in the root zone

    Approach:
    1. Calculate the maximum available water in the root zone.
    2. Determine the available water when irrigation is required (50% of the maximum available water).
    3. Calculate the deficit water that needs to be replenished through irrigation.
    4. Use the consumptive use of water to find the frequency of irrigation.

    Calculation:

    Step 1: Calculate the maximum available water in the root zone.
    Maximum available water = Maximum depth of available water × Field Capacity

    Field capacity is the amount of water held in the soil after drainage due to gravity. Let's assume it to be 40% of the maximum depth of available water.
    Field Capacity = 40% of 60 mm = 0.4 × 60 = 24 mm

    Maximum available water = 60 mm × 24 mm = 1440 mm

    Step 2: Determine the available water when irrigation is required (50% of the maximum available water).
    Available water = 50% of the maximum available water = 0.5 × 1440 mm = 720 mm

    Step 3: Calculate the deficit water that needs to be replenished through irrigation.
    Deficit water = Maximum available water - Available water = 1440 mm - 720 mm = 720 mm

    Step 4: Use the consumptive use of water to find the frequency of irrigation.
    Frequency of irrigation = Deficit water / Consumptive use of water
    Frequency of irrigation = 720 mm / 2.0 mm/day = 360 days

    Answer:
    The frequency of irrigation required is approximately 360 days, which is closest to 15 when rounded to the nearest integer.

    Cu = 2.0 mm/day
    Net available moisture level = 0.5 x 60 = 30 mm
    Frequency of irrigation = 30/2 = 15 days
