Worksheet time: 10mins
Consumptive Irrigation Requirement (CIR) is given by
CIR = Cu + Re
CIR = Cu − Re
CIR = (Cu − Re) + leaching water
CIR = NIR / eta_a
Net Irrigation Requirement (NIR) equals
(Cu − Re) only
(Cu − Re) + leaching water
NIR / eta_a
FIR / eta_c
Field Irrigation Requirement (FIR) is
FIR = NIR / eta_a
FIR = CIR / eta_a
FIR = NIR / eta_c
FIR = GIR × eta_c
Gross Irrigation Requirement (GIR) is
GIR = FIR × eta_c
GIR = FIR / eta_c
GIR = NIR / eta_a
GIR = CIR + Re
Which inequality is correct?
CIR > NIR > FIR > GIR
GIR > FIR > NIR > CIR
FIR > GIR > NIR > CIR
NIR > FIR > GIR > CIR
Gross Commanded Area (GCA) includes
Only cultivated fields
Only CCA and cropped area
Marshy lands, forests, roads, villages, barren land etc.
Only irrigated area in a season
Duty represents
Total depth of water required by crop
Time from sowing to harvesting
Irrigating capacity of unit quantity of water
Rainfall received during crop period
Yearly intensity of irrigation can be more than 100% (a)
Crop period is always less than base period (a)
Assertion: GIR is always greater than FIR. Reason: GIR includes conveyance losses, so it must exceed FIR.
Both A and R are true and R is correct explanation of A
Both A and R are true but R is not the correct explanation
A is true but R is false
A is false but R is true
