Rice, as Oryzae sativa L., is a leading food crop, the staple food of over half the world population. Although it is generally considered (land grown as) a semiaquatic annual grain plant, varieties grow in areas from deeply flooded land to dry, hilly slopes, and (like wheat) on every continent except Antarctica. The gross yield of rice per unit of land area is second only to that of corn, but its net food yield is the highest of any cereal grain. The harvested grain before hulling before hulling is known as rough rice.
The world crop for 1988-89 was estimated to be 477 million metric
