Question

Why is drip irrigation excellent for areas like Rajasthan?

Answer 1

Hint: Irrigation is the process by which water is supplied to plants and crop in a controlled manner and at specific intervals. Irrigation not only helps in the growth of plants in dry areas but also in suppression of dust, disposal of sewage and mining.

Complete answer:
Irrigation can be of several different types such as surface irrigation, micro-irrigation, drip irrigation, sprinkler irrigation and subirrigation. Surface irrigation is known as the oldest form of irrigation that is also known as gravity irrigation. In case of surface irrigation movement of water occurs across the agricultural land in order to wet it and seep into the soil. Micro-irrigation which is also known as localized irrigation is a type of irrigation where distribution of water takes place under low pressure through a pipe network to each plant. Drip irrigation is a type of micro-irrigation where water falls drop by drop directly to the roots and is also the most efficient method of irrigation. Sprinkler irrigation system is one where sprinklers are distributed throughout fields, the sprinklers are connected to a water supply that sprays water into the fields. Subirrigation is the type of irrigation that helps to raise the level of water table which in turn moistens the soil. Rajasthan is a place that has scarcity of water hence drip irrigation is most suited since it is not only highly efficient but wastage of water by drip irrigation is also the least.

Note: Different kinds of irrigation systems across the world since it increases crop productivity but sometimes few complications may also arise as a result of irrigation like drainage problems, altered soil salinity and clogging of soil.
