Consider the following data:
Consumptive use = 2.8 mm/day
Root zone depth = 8 cm
Irrigation efficiency =65%
Readily available moisture = 80% depth of root zone
The frequency of irrigation will be __________ days.

Solution

The correct option is A 22
Available soil moisture depth,
$= 0.80 \times 80 = 64 m m$

Frequency of irrigation,
$= \frac{Depth of available soil moisture}{Moisture consumed per day i.e. consumptive use}$

$= \frac{64}{2.8} = 22.86 d a y s$

$≃ 22 d a y s (s a y)$

The moisture content of the soil in the root zone of an agricultural crop at a certain stage is found to be $0.05$ . The field capacity of the soil is $0.15$ . The root zone depth is $1.2 m$ . The consumptive use of crops at this stage is $3 m m / d a y$ and there is no precipitation during this period. Irrigation efficiency is $65 %$ . It is intended to raise the moisture content to the field capacity in $8$ days through irrigation. The necessary depth of irrigation required is__

Q. In a cultivated area, the soil has porosity of 45% and field capacity of 38%. For a particular crop, the root zone depth is 1.0 m, the permanent wilting point is 10% and the consumptive use is 15 mm/day. If the irrigation efficiency is 60%, what should be the frequency of irrigation such that the moisture content does not fall below 50% of the maximum available moisture?

Q. During a particular stage of the growth of a crop, consumptive use of water is 2.8 mm/day. If the amount of water available in the soil is 25% of 80 mm depth of water, what is the frequency of irrigation?
