Total questions: 15
Worksheet time: 8mins
The water application efficiency of sprinkler irrigation given in the notes is:
60%
70%
80%
95%
Drip irrigation is best described as:
Water applied over land surface by gravity
Water directly applied to the root zone through low pressure pipes
Water applied by flooding the field
Water stored and released periodically
The highest water application efficiency mentioned in the notes is for:
Surface irrigation
Furrow irrigation
Sprinkler irrigation
Drip irrigation
Drip irrigation is mostly suitable in:
Heavy clay soils with abundant water
Water scarcity areas and saline soils
High rainfall humid regions only
Areas requiring large depth irrigation
Which is NOT a limitation of sprinkler irrigation as per the notes?
Not suggested in heavy wind/high temperature areas
Costly to install, operate and maintain
Water must be clean
Best suited for crops requiring larger depth of irrigation
Which component set is correctly listed as part of drip irrigation system?
Pump, filters, mainline, submain, emitters/drippers
Sluice gate, weir, spillway, canal regulator
Gauge glass, condenser, boiler, turbine
Intake well, sedimentation tank, rapid sand filter
Fertigation is best defined as:
Application of water without fertilizers
Application of fertilizers along with irrigation water
Application of pesticides through air
Application of compost only around plant
Sprinkler irrigation cannot be suggested in heavy wind and high temperature areas.
True
False
Drip irrigation is suitable for closely planted crops like rice and wheat.
True
False
Assertion (A): Drip irrigation provides the highest water application efficiency (90–95%). Reason (R): In drip irrigation, water is directly applied to the root zone through low pressure pipes.
Both A and R are true and R is the correct explanation of A
Both A and R are true but R is not the correct explanation of A
A is true and R is false
A is false and R is true
Water application efficiency of sprinkler irrigation is (a) .
Drip irrigation is also known as (a) irrigation.
In drip irrigation, water is directly applied to the (a) zone.
Drip irrigation works through pipes of (a) pressure.
The process of providing an impervious layer surrounding the plant to reduce evaporation loss is called (a) .
