1.

Consumptive Irrigation Requirement (CIR) is given by

a)

CIR = Cu + Re

b)

CIR = Cu − Re

c)

CIR = (Cu − Re) + leaching water

d)

CIR = NIR / eta_a

2.

Net Irrigation Requirement (NIR) equals

a)

(Cu − Re) only

b)

(Cu − Re) + leaching water

c)

NIR / eta_a

d)

FIR / eta_c

3.

Field Irrigation Requirement (FIR) is

a)

FIR = NIR / eta_a

b)

FIR = CIR / eta_a

c)

FIR = NIR / eta_c

d)

FIR = GIR × eta_c

4.

Gross Irrigation Requirement (GIR) is

a)

GIR = FIR × eta_c

b)

GIR = FIR / eta_c

c)

GIR = NIR / eta_a

d)

GIR = CIR + Re

5.

Which inequality is correct?

a)

CIR > NIR > FIR > GIR

b)

GIR > FIR > NIR > CIR

c)

FIR > GIR > NIR > CIR

d)

NIR > FIR > GIR > CIR

6.

Gross Commanded Area (GCA) includes

a)

Only cultivated fields

b)

Only CCA and cropped area

c)

Marshy lands, forests, roads, villages, barren land etc.

d)

Only irrigated area in a season

7.

Duty represents

a)

Total depth of water required by crop

b)

Time from sowing to harvesting

c)

Irrigating capacity of unit quantity of water

d)

Rainfall received during crop period

8.

Yearly intensity of irrigation can be more than 100% (a)  

9.

Crop period is always less than base period (a)  

10.

Assertion: GIR is always greater than FIR. Reason: GIR includes conveyance losses, so it must exceed FIR.

a)

Both A and R are true and R is correct explanation of A

b)

Both A and R are true but R is not the correct explanation

c)

A is true but R is false

d)

A is false but R is true
