Agriculture in ancient India began around 9000 BCE, marking one of the earliest instances of settled farming in the world. The Neolithic Revolution saw the domestication of plants and animals, with early cultivation of wheat, barley, jujube, sheep, and goats at sites like Mehrgarh (c. 8000–6000 BCE). In the Indus Valley Civilization (c. 3300–1300 BCE), agriculture advanced significantly with irrigation systems, canals, reservoirs, and the use of animal-drawn ploughs. Crops included wheat, barley, rice, peas, sesame, dates, and cotton, with cotton spinning and textile production becoming well-developed industries.
During the Vedic period (1500–500 BCE), farming became central to society, with texts like the Rigveda describing ploughing, seed broadcasting, fallowing, crop rotation, and manuring using cow dung. The introduction of iron tools around 1200 BCE revolutionized agriculture, enabling forest clearance and expansion into the fertile Gangetic plains. The Mauryan Empire (322–185 BCE) institutionalized agricultural management through the Arthasastra, which detailed soil classification, meteorological observations, dam construction, and state-supported irrigation.
Sustainable practices were deeply embedded in ancient Indian farming, including mixed farming, water conservation, and reverence for nature. The Chola Empire (875–1279 CE) developed advanced tank-and-channel irrigation systems, while Kallanai Dam on the Kaveri River (1st–2nd century CE) remains one of the oldest water-regulation structures still in use. Ancient India also pioneered sugar production, with crystallized sugar (khanda) developed by 500 BCE and later spread to China.
Key crops across regions included rice, millets (like finger, foxtail, and kodo), pulses, sugarcane, cotton, and spices such as black pepper and cardamom. Trade networks connected India to Mesopotamia, Egypt, and Rome, exporting spices, textiles, and sugar while importing new crops and technologies.
