Indian agriculture began by 9000 BCE on north-west India with the early cultivation of plants, and domestication of crops and animals. Indian subcontinent agriculture was the largest producer of wheat and grain. They settled life soon followed with implements and techniques being developed for agriculture. Double monsoons led to two harvests being reaped in one year. Indian products soon reached the world via existing trading networks and foreign crops were introduced to India. Plants and animals—considered essential to their survival by the Indians—came to be worshiped and venerated.

The early Dravidian religion constituted a non-Vedic form of Hinduism in that they were either historically or are at present Āgamic. The Agamas are non-Vedic in origin, and have been dated either as post-Vedic texts, or as pre-Vedic compositions. The Agamas are a collection of Tamil and Sanskrit scriptures chiefly constituting the methods of temple construction and creation of murti, worship means of deities, philosophical doctrines, meditative practices, attainment of sixfold desires and four kinds of yoga. The worship of tutelary deity, sacred flora and fauna in Hinduism is also recognized as a survival of the pre-Vedic Dravidian religion. Dravidian linguistic influence on early Vedic religion is evident, many of these features are already present in the oldest known Indo-Aryan language, the language of the Rigveda, which also includes over a dozen words borrowed from Dravidian. The linguistic evidence for Dravidian impact grows increasingly strong as one moves from the Samhitas down through the later Vedic works and into the classical post-Vedic literature. This represents an early religious and cultural fusion or synthesis between ancient Dravidians and Indo-Aryans that went on to influence Indian civilization.
Irrigation in India includes a network of major and minor canals from Indian rivers, groundwater well based systems, tanks, and other rainwater harvesting projects for agricultural activities. Of these groundwater system is the largest. In 2013–14, only about 36.7% of total agricultural land in India was reliably irrigated, and remaining 2/3 cultivated land in India is dependent on monsoons. 65% of the irrigation in India is from groundwater. Currently about 51% of the agricultural area cultivating food grains is covered by irrigation. The rest of the area is dependent on rainfall which is most of the times unreliable and unpredictable.
