Rice

Rice is the seed of the grass species Oryza sativa or less commonly Oryza glaberrima. The name wild rice is usually used for species of the genera Zizania and Porteresia, both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of Oryza.
As a cereal grain, domesticated rice is the most widely consumed staple food for over half of the world’s human population, especially in Asia and Africa. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize.
