Is it important to increase the area
under irrigation? Why?
what are the sources of irrigation
Answers
Yes, it is important to increase the area under irrigation because water is very essential for agriculture. In India, the rainfall is unevenly distributed in the country and if rainfall is less, then production will be low, and they will be only able to grow one crop in a season.
Answer:
Yes, it is important to increase the area under irrigation because water is very essential for agriculture. In India, the rainfall is unevenly distributed in the country and if rainfall is less, then production will be low, and farmers will be only able to grow one crop in a season. With good irrigation facilities, it will be possible to do multiple cropping, helping to increase the yield per hectare.
There are three basic types of irrigation here in India which I describe here below briefly:-
CANALS
Canals are one of the oldest amd most important sources of irrigation in India. Canal irrigation is, however, largely confined to the Great Plains of India (Punjab, Haryana, Uttar Pradesh, Uttarakhand, Rajasthan, Bihar and West Bengal) and the fertile plains if India (Andhra Pradesh, Karnataka, Madhya Pradesh Odisha and Tamil Nadu). Some popular canals are The Bari Doab Canal, Bhakhra Canal, Indhira Gandhi Canal, Eastern and Western Yamuna Canals, The Ganga Canal, Agra and Sharda Canals are some of the important irrigation system of India.
WELL AND TUBEWELLS
Well and tubewells irrigates the largest cropped area of the country. About 54 percent of the total irrigated are is under tubewell and well irrigation. Tubewell irrigation is extensively developed in Northern Plains of India. About 95 percent of the tubewells are located in Uttar Pradesh, Punjab, Haryana, Gujrat, Bihar, Madhya Pradesh, Maharashtra, Andhra Pradesh, Karnataka, West Bengal and Odisha.
TANKS
Tank irrigation is generally practiced in the eastern part of the Deccan Plateau where the topography is suitable for erecting dams across small rivulets and for the collection of water in artificial tanks. Tanks are found in large number in the districts of Chengalpattu, North Arcot and South Arcot in Tamil Nadu, Nellore and Warangal districts of Andhra Pradesh.
SPRINKLE IRRIGATION
The method of sprinkle water is in a manner similar to rainfall. This is the most brillian method of savimg water upto 30 to 50 per cent as compared to surface irrigation.
DRIP IRRIGATION
Drip irrigation has the advantages of water saving and more suitable to poor soils, no soil erosion and improves the efficiency of fertilisers.
