Higher production is due to the existence of the coastal alluvium soil very suitable for the cultivation of paddy and pulses.

In the early days, agriculturists in Karaikal district had to depend on inundation following floods in Cauveri or local rainfall. The main branches of Cauveri below the grand anicut are the Kodamurutti, Arasalar, Virasolanr and Vikramanar. They break again into a number of distributaries and some flow across Karaikal district before entering the Bay of Bengal. Canals are the exclusive meansfor carrying out irrigation in Karaikal.
