  3. Q3

    1. a)

      Estimate the potential evapotranspiration (PET) of an area for the month October and November in which sugarcane is grown. The latitude of the area is 18ºN. The average value of crop coefficient K = 0.95 in Blaney- Criddle formula. The mean monthly temperature for the month October and November is 75ºF (=23.89ºC) and 72ºF (=22.22ºC). Use Table (3a) to calculate monthly daytime hours percentage. Table 3a: Monthly daytime hours percentages, Ph, for use in Blaney- Criddle formula North latitude (deg) Oct.

  4. Q4

    1. a)

      Explain with neat sketch how soil texture and structure affect water movement in soil.

      [6]
    2. b)

      A crop has effective root zone depth of 1200 mm and monthly (30 days) crop evapotranspiration of 260 mm. The effective rainfall during the 30 days period is 20mm. The field capacity and permissible soil moisture depletion (volume basis) are 16% and 8% respectively. Determine the irrigation interval in days for the crop.
