It has been built at a strategic point where two hills on either side of the Sutlej are very close to each other. It is the highest gravity dam in the world. Its length is 226 metres from the river bed. The canals taken out are 1100 kilometres long. The \u2018Nangal Power Plant\u2019 on the Sutlej produces electricity, and serves the states of Himachal Pradesh, Punjab, Haryana, Rajasthan and New Delhi. The distributaries are 8400 km in length. It irrigates an area of 1.4 million hectares.<\/p>\n

The waters of the River Beas and the Ravi are diverted to the River Sutlej. The \u2018Pong\u2019 Dam on the River Beas has been constructed to divert the Beas water into the Sutlej in a regulated manner. So that \u2018Rajasthan canal\u2019, the longest irrigation canal in the world can irrigate Gandhi Nagar, Bikaner and Jaisalmer districts of North West Rajasthan, (i.e) a part of Thar desert. The main canal now called \u2018Indira Gandhi Canal\u2019 is 468 km long runs entirely in Rajasthan, Western of Sutlej, Beas and Ravi are now being fully utilised for irrigating thirsty lands of South Western parts of our country.<\/p>\n

                                      Due to increased use of High Yielding Variety (HYV) seeds (CR Dhan 205, AR Dhan 306, CRR 451 etc.), many of the indigenous varieties were disappeared. In 2016, the first 10 leading rice-producing states are West Bengal (First in India) Uttar Pradesh, Punjab, Tamil Nadu, Andhra Pradesh, Bihar, Chhattisgarh, Odisha, Assam, and Haryana.<\/p>\n

                                      Wheat:
                                      \nWheat is a temperate crop. Its cultivation is mainly confined to the northwestern part of India. India produces both winter wheat and spring wheat. It is the second most important food crop of the country, after rice.<\/p>\n

                                      It requires 10-15\u00b0C at the time of sowing and 20-25\u00b0C at the time of ripening of grains. Over 85% of India\u2019s wheat production comes from 5 states namely Uttar Pradesh, Punjab, Haryana, Rajasthan and Madhya Pradesh. Apart from these regions, the black soil tract of the Deccan covering parts of Maharashtra and Gujarat also contribute a major wheat production.<\/p>\n

                                      IX. HOTS Questions<\/span><\/p>\n

                                      Question 1.
                                      \nCan you imagine a world without agriculture?
                                      \nAnswer:
                                      \nAgriculture is the art and science of cultivating the soil, growing crops and raising livestock. It includes the preparation of plant and animal products for people to use and their distribution to markets.<\/p>\n

                                      Agriculture provides most of the world\u2019s food and fabrics. Cotton, wool and leather are all agricultural products. It also provides wood for construction and paper products.<\/p>\n

                                      A world without agriculture would be very different compared to the world we live in today. It is easy for us as humans to take for granted things when we don\u2019t really know how they are grown or produced. Without agriculture, we may not get food and clothing. Without timber, we may not be able to build houses and furniture. We may also be deprived of some everyday-products like soap, paper and ethanol, which are made up of some sort of agricultural by-product. Modern medicine also depends on agriculture. Without agriculture, we wouldn\u2019t be here. We must always be thankful for this industry and for those involved in the various activities related to it.<\/p>\n

                                      Question 2.
                                      \nCan you give solutions for the prevailing water disputes in South India (construction of dams \/ raising of dams \/ cleaning of tanks}?
                                      \nAnswer:<\/p>\n

                                        \n

                                      2. Raising of dams: Improves the storage capacity, Strengthening the dams is a must.<\/li>\n
                                      3. Cleaning of tanks: Preventing encroachment by strict legal action, desilting the tanks and deepening it in the local areas will provide water supply to the locality, as well as to maintain the areas of ground water level cleaning of tanks is a must<\/li>\n<\/ol>\n
