Irrigation Engineering MCQ Bullet Points

  • Method of pricing irrigaiton water is – flat rate pricing, volumetric method of pricing
  • Percentage of water available on earth that is saline is – 97%
  • Irrigation is basically required in – Humid region, Arid regions, semi arid regions
  • Name the type of irrigation, when a storage weir is constructed across the river and water is stored in a reservoir or lake – tank irrigation
  • minor irrigation serves – upto 2000 hectares
  • Best method of assessment of irrigation water is – volumetric rate
  • Irrigation is needed where rainfall is – scarce (low)
  • Method of applying water directly to root zone of plant is called Drip Irrigation
  • For a furrow slope of 0.3% pure depth for the use of water in clay should not be less than 390mm
  • The maximum water application efficiency – sub surface irrigation
  • When Crops are grown on ridges, running on the sides of the ditches then the kid of irrigation adopted is called as furrow
  • Name the method of irrigation which does not come under control plating- wild flooding
  • In which method the field is divided into a number of long parallel strips-border flooding irrigation
  • Because of large stream discharge…… Irrigation is more suitable for permeable soil – check flooding
  • Irrigation water eyed to the land by means gravity flow indicates which of the type of irrgation – flow irrigation
  • For row crops the most commonly adopted method of surface irrigation is- furrow and corrugation irrigation
  • Basically irrigation engineering is related to purpose of – nutrients of crops
  • The method of growing crop on running on the sides of water ditches used in certain agriculture field is called as – Furrow Irrigation
  • To reduce the salinity by leaching the best method of irrigation – chak flooding
  • Irrigation with sewage from a town is – broad irrigation
  • Furrow method of irrigation is most suitable for potatos
  • Method of applying water may be used on rolling land – free flooding
  • Furrow irrigation is – very common
  • The most suitable method of irrigation for area having low rainfall and strong winds is – drip irrigation
  • The conjunctive use of water in a basin means – combined use of surface and groundwater resources
  • Which technique of water distribution in farm is called Trickle irrigation – drip irrigation
  • The suitable method for irrigation highly modulating land is – sprinkler irrigation
  • In arid area with uneven land surface most suitable method of irrigation is – sprinkler irrigation
  • The maximum application rate by sprinkler is limited by – the infiltration capacity of the soil
  • The method of irrigation has minimum wastage of water – sprinkler irrigation
  • Sprinkler irrigation is preferred when – ground is undulating, the crop has Shallow roots, irrigation water is scarce
  • In which method water is sprayed in the air simulating rainfall – sprinkler irrigation
  • About 80% irrigation efficiency is possible with the sprinkler irrigation particularly in – humid and semi arid region
  • The system of irrigation in which water is supplied to the field by mean of network of pipe having spray nozzle is- sprinkler irrigation
  • Method of irrigation has minimum wastage of water – sprinkler irrigation
