Rice is normally grown as an annual plant, although in tropical areas it
can survive as a perennial and can produce a ratoon crop for up to 30
years. The rice plant can grow up to 3.3–5.9 ft tall, occasionally more
depending on the variety and soil fertility. It has long, slender leaves
50-100 cm long and 2-2.5 cm broad. The small wind-pollinated flowers are
produced in a branched arching to pendulous inflorescence 30-50 cm long.
The edible seed is a grain 0.5-1.2 cm long and 2-3 mm thick.
Rice cultivation is well-suited to countries and regions with low labor
costs and high rainfall, as it is labor-intensive to cultivate and
requires ample water. Rice can be grown practically anywhere, even on a
steep hill or mountain. Although its parent species are native to South
Asia and certain parts of Africa, centuries of trade and exportation have
made it commonplace in many cultures worldwide.
