Séd so far in Nepal with
(b) Calculate volume of water to irigate a field plot of 5ha with the
following data:
(a) Existing soil moisture content is 20%
(b)
Field capacity is 30%
(c)
Dry unit wt of soil is 15.20 kN/m³
(d)
Effective root zone depth is 90 cm
(e)
Water application efficiency is 60% at head to 85% at tail
end of field, and
Conveyance efficiency of water course is 90%
If supply of water to water course is at 30 1/s for 12 hrs. only,
find interval of irrigation for crop having evapotranspiration as
5mm/day. Also find number of field plots irrigated per day if 30
has of command area is constituted by field plots.
