Consider the following statements regarding irrigation: Drip irrigation system, also known as the 'trickle irrigation system' where water is applied on the soil surface at a rate lower than the infiltration rate of the soil. Sprinkler irrigation is not suitable if a site is known to be windy most of the time. Which among the following above given statements are correct?

Consider the following statements regarding irrigation: Drip irrigation system, also known as the 'trickle irrigation system' where water is applied on the soil surface at a rate lower than the infiltration rate of the soil. Sprinkler irrigation is not suitable if a site is known to be windy most of the time. Which among the following above given statements are correct? Correct Answer Both 1 and 2

The correct answer is Both 1 and 2.

Key Points

  • Drip irrigation system, also known as the ‘trickle irrigation system’, is a method of applying the required amount of water directly to the root zones of plants through drippers or emitters at frequent intervals. 
    • In this system, water is applied drop-by-drop or by a micro jet on the soil surface or sub-surface at a rate lower than the infiltration rate of the soil. Hence statement 1 is correct.
  • Sprinkler irrigation is a method of applying water in a manner similar to rain. It is suited for most row, field and tree crops.
    • Water can be sprayed over or under the crop canopy.
    • If a site is known to be windy most of the time, sprinkler irrigation will not be suitable. Hence statement 2 is correct.

1996-7 and 2002-3, the area under canal irrigation declined by 2.4 million ha (13.8 percent), the area under tank irrigation fell by 1.4 million ha (42.4 percent), and the area irrigate by all other sources declined by 1 million ha (28 percent). The only irrigation source that increased its share was groundwater wells, by 2.8 million ha (more than 9 percent) Why has such a change in irrigation demands happened? 1. Not enough supply of water from canals 2. More tubewell irrigation by farmers in the source areas of rivers 3. High cost of irrigation water, and  diversion for non-farm use 4. Joint use of water not possible due to social and economic inequalities
