Paddy is also called rice paddy. A small level flooded field is used to cultivate rice in southern and eastern Asia. Wet-rice cultivation is the most prevalent method of farming in the Far East, where it utilizes a small fraction of the total land yet feeds the majority of the rural population. Rice was domesticated as early as 3500 bc, and by about 2,000 years ago it was grown in almost all of the present-day cultivation areas, predominantly deltas, floodplains and coastal plains, and some terraced valley slopes. Many rice paddies are flooded by rivers and rainfall during monsoon season, while others must be irrigated. These paddies have impermeable subsoil and are bordered by earthen bunds to hold an average of 4â6 inches (10â15 centimetres) of water in the field for three-quarters of the growing season. In all countries, excluding India, paddies are worked by family labour alone and by the same methods as were used 2,000 years ago: hand cultivation with hoe and spade, or water-buffalo-, horse-, or ox-drawn plough with metal share.
