  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
  • Sources of irrigation water include groundwater, through springs or wells, surface water, through rivers, lakes, or reservoirs, or even other sources, such as treated wastewater or desalinated water.
  • Hence Water from rivers is the only source for irrigation in the fields is a false statement.
  • So, the correct answer is 'False'.

Which irrigation technique is considered the most water efficient? 

  1. Surface

  2. Drip

  3. Sprinkler

  4. Spray
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Drip irrigation is most economical and efficient technique of irrigation. Watering plants by drip irrigation method is a more economical way of watering plants. In this technique, water is supplied drop by drop near the plant roots through the small opening is called as drippers. By this method, there is no loss of water due to seepage, runoff or evaporation. Thus, the correct answer is option B.

Of the following all are the traditional method of irrigation except

  1. Chain pump

  2. Pulley system

  3. Persian wheel

  4. Basin irrigation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Basin irrigation is a type of surface irrigation especially in regions with layouts of small fields having level surfaces and surrounded by low bunds which prevent the water from flowing to the adjacent fields. This method is generally suitable for crops that are unaffected by standing water for long periods. for e.g., rice cultivation areas.
Chain pump, pulley system, and persian wheel belongs to the traditional system of irrigation.
So, the correct answer is option D.

  2. Furrow irrigation

  3. Basin irrigation

  4. All of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A. Drip irrigation is a system of 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. Sprinkler irrigation is the method of applying water to a controlled manner in that is similar to rainfall. This too is done to reduce the wastage of water . 
C. Furrow irrigation is conducted by small parallel channels among the field length in the direction of slope . 
D. Basin irrigation is where water is applied & distributed over the soil surface by gravity. 
So the correct options is ' Drip Irrigation & Sprinkler irrigation ' .
