Compare among furrow , basin and sprinkler irrigation.
Answers
Answer:
Furrow irrigation
Furrow irrigation method is resorted to where crops are one grown in rows. Along the side of rows of crops, ‘Dol’is formed, and in between two such ‘Dols’, a furrow is formed in which water flows for irrigation. The quantity of flow of water depends on demand of water by plants and the rate of infiltration.
Basin irrigation
Basin irrigation is one of the oldest methods of irrigating and is widely practiced where rice is irrigated.The basin is formed by leveling the area completely and enclosing it with berms, or levees. The side berms will run essentially on the contour. If the land is very sloping, the berms become terraces and a large amount of earth must be moved from the upper side to the lower side. On very steep slopes, the basin will be fairly narrow to reduce the amount of leveling required.
Sprinkler irrigation
Sprinkler irrigation is a method of applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. The pump supply system, sprinklers and operating conditions must be designed to enable a uniform application of water.
Answer:
Furrow irrigation method is resorted to where crops are one grown in rows.
In sprinkler irrigation method, water is taken from source to the fields through pipes, whereas in surface irrigation methods only 30-45 per cent water reaches the crops.
Basin irrigation is the simplest mode in which bunds of soil are made as a border all around the field and the field is then flooded with water.
