(c) sprinkler irrigation
(d) None of the above

Ans : (c) Sprinkle Irrigation method
• In this method, the irrigation water is applied to the land in the form of spray, somewhat as in ordinary rain through a network of pipes and pumps.
• It can be used for all the crops except rice and jute and for all the soils except very heavy soils (i.e soil with very low infiltration rates)
• Best suited for very light soils as deep percolation losses are avoided (light soils : These soil drain quickly after rain and watering).
• It is used mainly by cultivators of tea, coffee and vegetables.

Drip Irrigation Method/Trickle Irrigation
• It is one of the least method of Irrigation which is becoming increasingly popular in areas with acute scarcity of irrigation water and salt problems.
• In this method, water and fertilizer is slowly and directly applied to the root zone of the plants, in order to minimize the losses due to evaporation and percolation.
• This is achieved with the help of specially designed emitter and drippers.
• It is best suited for row crops and orchards such as tomatoes, ground nut, citrus melon etc.

Furrow method or Furrow Irrigation
• In this method water is applied to the land to be irrigated by a series of long, narrow field channels called furrows which are dug in the land at regular interval.
• The water flowing in the narrows infiltrate into the soil and spreads laterally to irrigate the land between the furrows.
• The crops are usually grown on the ridges between the furrows.
• It is commonly used for row crops such as maize, cotton, potatoes, sugarcane, sugar beet, groundnut tobacco etc
