The terraces are commonly thought to have been built with minimal equipment, rice oryza sativa by hand. They are fed by an ancient irrigation system from the rainforests above the terraces. By the 18th century, encroaching European expansionism in the rice oryza sativa increased rice production in much of Southeast Asia, and Thailand, then known as Siam.

British Burma became the world's largest exporter of rice, from the turn of the 20th century to the s, when neighbouring Thailand exceeded Burma.


In recent years, Vietnam has been a strong exporter, as well, occasionally eclipsing Thailand. While China, India, and Indonesia remain the top rice producers, they are also rice oryza sativa of the top rice consumers.

The flowers grow on broad, open terminal panicles branched clusters. The oblong spikelets, which each contain a rice oryza sativa flower that develops into a single kernel of grainare sparse along the stem rather than forming dense clusters.


The harvested kernel, known as a rice rice oryza sativa, is enveloped in a hull or husk that is removed during milling.

Rice yield productivity is greatly affected by different biotic stresses, like diseases and insect pests, and abiotic stresses like drought, cold, and salinity. Attempts to improve resistance in rice to rice oryza sativa stresses by conventional breeding through introgression of traits have limited success owing to a lack of resistance germplasm in the wild relatives.
