Rice is one of the most important food crops in the world and is grown in more than 100 countries on every continent of the world except Antarctica. However, rice is primarily grown and consumed in Asia. Only about 4-5% of the world rice production is traded internationally. Thailand is the world leading rice exporter and The United States is the second largest exporter. The world average rough rice yield was 3.56 ton ha in 1990. It was found that temperate areas have historically produced the highest average rice yield per hectare. In Taiwan, annual average rice yield was 4.3 ton ha1 in 1998 and the first rice crop has higher average rice yield than the second rice crop. Although rice is originated in tropics, remarkable ecogenetic diversification and adaptability to adverse environment exists because of its long history of cultivation selection under diverse hydro-edaphic-seasonal regime. Therefore, rice can be grown in adverse climate environmental conditions. The climatic factors such as rainfall, solar radiation, day length, temperature, relative humidity, and wind were discussed in the Chapter on the standpoint of rice production. A detailed physiological discussion will be given in other chapters of the volume.
