<P> A variety of tropical fruit such as mango and muskmelon are native to the Indian subcontinent . The Indians also domesticated hemp, which they used for a number of applications including making narcotics, fiber, and oil . The farmers of the Indus Valley, which thrived in modern - day Pakistan and North India, grew peas, sesame, and dates . Sugarcane was originally from tropical South Asia and Southeast Asia . Different species likely originated in different locations with S. barberi originating in India and S. edule and S. officinarum coming from New Guinea . </P> <P> Wild rice cultivation appeared in the Belan and Ganges valley regions of northern India as early as 4530 BCE and 5440 BCE respectively . Rice was cultivated in the Indus Valley Civilisation . Agricultural activity during the second millennium BC included rice cultivation in the Kashmir and Harrappan regions . Mixed farming was the basis of the Indus valley economy . Denis J. Murphy (2007) details the spread of cultivated rice from India into South - east Asia: </P> <P> Several wild cereals, including rice, grew in the Vindhyan Hills, and rice cultivation, at sites such as Chopani - Mando and Mahagara, may have been underway as early as 7000 BP . The relative isolation of this area and the early development of rice farming imply that it was developed indigenously...Chopani - Mando and Mahagara are located on the upper reaches of the Ganges drainage system and it is likely that migrants from this area spread rice farming down the Ganges valley into the fertile plains of Bengal, and beyond into south - east Asia . </P> <P> Irrigation was developed in the Indus Valley Civilisation by around 4500 BCE . The size and prosperity of the Indus civilisation grew as a result of this innovation, which eventually led to more planned settlements making use of drainage and sewers . Sophisticated irrigation and water storage systems were developed by the Indus Valley Civilisation, including artificial reservoirs at Girnar dated to 3000 BCE, and an early canal irrigation system from circa 2600 BCE . Archaeological evidence of an animal - drawn plough dates back to 2500 BC in the Indus Valley Civilisation . </P>
