Tamil Nadu has historically been an agricultural state, while its advances in other fields launched the state into competition with other areas. Even so, Tamil Nadu is a leading producer of agricultural products in India. Tamil Nadu agriculture is heavily dependent on the river water and Monsoon rains. The perennial rivers are Palar, Cheyyar, Ponnaiyar, Kaveri, Meyar, Bhavani, Amaravati, Vaigai, Chittar and Tamaraparani. Non-perennial rivers include the Vellar, Noyal, Suruli, Gundar, Vaipar, Valparai and Varshali. Tamil Nadu is also the leading producer of kambu, corn, rye, ground nuts, oil, seeds and sugar cane in India.
Erode is the world largest producer of turmeric. Around 68% of the world's turmeric and 84% of India's turmeric are from Erode. Also, Erode has the largest turmeric market in the world.
