  2. Channel pump

  3. basin irrigation

  4. Sprinkler
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. Drip irrigation is a system of a micro-irrigation system that allows the water to drip slowly to the roots of the plants. It is done in places where water is scarce.  
B. Channel irrigation allows irrigation over large areas, with large volumes of water.
C. Basin irrigation is a type of surface irrigation where water is applied and distributed over the soil surface by gravity.
D. A sprinkler is the method of irrigation by applying water similar to rainfall in a controlled manner.
So the correct option is 'Sprinkler'.

Multiple choice evs flow of water irrigation irrigation and its types irrigation and types

Which of the following is used maximum for lifting water from wells?

  1. Persian wheel (Rahat)

  2. Swing basket (Bedi)

  3. Dhenkuli

  4. Don
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

  • Rahat system of irrigation is a way to get water from a well in which large wheels are used. It is tied to oxen and is turned by them to get water out of the wells. 
  • As many wheels are used in this system so it can lift up much water into the field. 

So, the correct option is 'Persian wheel (Rahat)'.

Multiple choice evs flow of water irrigation irrigation and its types irrigation and types

Which of the following is used for lifting water from 8-10 m depth?

  1. Washer Rahat

  2. Hand pump

  3. Mayadar lift

  4. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

(A) Washer Rahat is the oldest system of irrigation system where animals are used to get water out of the well. It is made up of wheel and buckets attached to it with a chain. It can lift water up to 1-3 m depth

(B) Hand pumps are used in sprinkler irrigation systems. A hand pump can lift up water less than 7 m depth.
(C) Mayadar lift is a type of irrigation system in which water is lifted by an external force.
So, the correct answer is 'None of the above'

Multiple choice evs flow of water irrigation irrigation and its types irrigation and types

........... allows the control of flow of water during irrigation.

  1. Rahat

  2. Pulley system

  3. Lever system

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Lever systems allow the user to control the speed of irrigation by choosing slow, medium or fast water flow; however, the lever system method is not as ancient, or inexpensive, as other methods. 

Therefore, the correct answer is option C.
