Rice production by country (2019) This is a list of countries by rice production in 2022 based on the Food and Agriculture Organization Corporate Statistical Database. The total world rice production for 2022 was 776,461,457 [1] metric tonnes. In 1961, the total world production was 216 million tonnes.
The average world yield for rice was 4.7 metric tons per hectare (2.1 short tons per acre), in 2022. [37] Yuan Longping of China's National Hybrid Rice Research and Development Center set a world record for rice yield in 1999 at 17.1 metric tons per hectare (7.6 short tons per acre) on a demonstration plot.
Rice raised in the well-watered lowland areas is known as lowland or wet rice. In the hilly areas, slopes are cut into terraces for the cultivation of rice. Thus, the rice grown in the hilly areas is known as dry or upland rice. The yield of upland rice per hectare is comparatively less than that of wet rice.
Grains of rice Rice production in Texas began in 1853 in southeast Texas. By 1903, the acres of cultivated rice in Texas was second only to Louisiana and together accounted for 99 percent of rice production in United States. While other states have surpassed Texas in rice production, it remains a significant Texas crop into the foreseeable future.
The proportion of "miracle" rice in total output rose from zero in 1965–66 to 81 percent in 1981–82. [4] Average productivity increased from 1.23 metric tons per hectare in 1961 to 3.59 metric tons per hectare in 2009. [1] This green revolution was accompanied by an expanded use of chemical inputs.
The units by which the yield of a crop is usually measured today are kilograms per hectare or bushels per acre. Long-term cereal yields in the United Kingdom were some 500 kg/ha in Medieval times, jumping to 2000 kg/ha in the Industrial Revolution, and jumping again to 8000 kg/ha in the Green Revolution. [1] Each technological advance ...
It produces the highest rice yields in Asia, at 6.5 metric tons per hectare (2.6 long ton/acre; 2.9 short ton/acre). [4] Rice is produced throughout the nation and is believed to have been first domesticated in the surrounding regions of the Yangtze River and the Yunnan-Guizhou highlands of Southern China.
From 1968 to 1989, annual rice production had increased from 12 million to over 40 million tons, and yields had increased from 2.14 tons of padi (wet rice growing) per hectare to 4.23 tons per hectare. [10] The most significant factor in this impressive increase in output and productivity was the spread of high-yield rice varieties.
