Query: What is the most abundant crop in China?
About 75% of China's cultivated area is used for food crops. Rice is China's most important crop, raised on about 25% of the cultivated area. The majority of rice is grown south of the Huai River, in the Zhu Jiang delta, and in the Yunnan, Guizhou, and Sichuan provinces.
Wheat is produced in almost every state in the United States, and is the principal cereal grain grown in the country. The type and quantity vary between regions. The US is ranked third in production volume of wheat, with almost 58 million tons produced in the 2012–2013 growing season, behind only China and India (But the combined production of all European Union nations is larger than that of China). The US is ranked first in crop export volume; almost 50% of its total wheat production is exported.
Guangdong (; formerly romanised as Kwangtung or Canton Province) is a province in South China, on the South China Sea coast. Guangdong surpassed Henan and Shandong to become the most populous province in China in January 2005, registering 79.1 million permanent residents and 31 million migrants who lived in the province for at least six months of the year; the total population was 104,303,132 in the 2010 census, accounting for 7.79 percent of Mainland China's population. This also makes it the most populous first-level administrative subdivision of any country outside of South Asia, as its population is surpassed only by those of the Pakistani province of Punjab and the Indian states of Bihar, Maharashtra and Uttar Pradesh. The provincial capital Guangzhou and economic hub Shenzhen are among the most populous and important cities in China. The population increase since the census has been modest, the province registering 108,500,000 people in 2015.
Present-day Poland is a country with favorable agricultural prospects, and over two million private farms. It is the leading producer of potatoes and rye in Europe, the world's largest producer of triticale, and one of the more important producers of barley, oats, sugar beets, flax, and various fruits. It is also the European Union's fourth largest supplier of pig meat after Germany, Spain and France.
The Japanese agricultural sector accounts for about 1.4% of the total country's GDP. Only 12% of Japan's land is suitable for cultivation. Due to this lack of arable land, a system of terraces is used to farm in small areas. This results in one of the world's highest levels of crop yields per unit area, with an overall agricultural self-sufficiency rate of about 50% on fewer than 56,000 km² (14 million acres) cultivated.
One species, "Sorghum bicolor", native to Africa with many cultivated forms now, is an important crop worldwide, used for food (as grain and in sorghum syrup or "sorghum molasses"), animal fodder, the production of alcoholic beverages, and biofuels. Most varieties are drought- and heat-tolerant, and are especially important in arid regions, where the grain is one of the staples for poor and rural people. These varieties form important components of forage in many tropical regions. "S. bicolor" is an important food crop in Africa, Central America, and South Asia, and is the fifth-most important cereal crop grown in the world.
Maize has been a staple food for centuries. It is the most planted crop in the Mexican region. The country grows more than 42 different types of maize, each of which has several varieties whose number is estimated at more than 3,000 by the International Center for the Improvement of Maize and Wheat (CIMMYT). The characteristics of each variety depend upon soil conditions, humidity, altitude, and how cultivated. Some of the earliest evidence of maize cultivation suggests that domestication took place in several places at the same time.

Wild grains were collected and eaten from at least 20,000 BC. From around 9500 BC, the eight Neolithic founder crops – emmer wheat, einkorn wheat, hulled barley, peas, lentils, bitter vetch, chick peas, and flax – were cultivated in the Levant. Rye may have been cultivated earlier but this remains controversial. Rice was domesticated in China by 6200 BC with earliest known cultivation from 5700 BC, followed by mung, soy and azuki beans. Pigs were domesticated in Mesopotamia around 11,000 BC, followed by sheep between 11,000 BC and 9000 BC. Cattle were domesticated from the wild aurochs in the areas of modern Turkey and Pakistan around 8500 BC. Sugarcane and some root vegetables were domesticated in New Guinea around 7000 BC. Sorghum was domesticated in the Sahel region of Africa by 5000 BC. In the Andes of South America, the potato was domesticated between 8000 BC and 5000 BC, along with beans, coca, llamas, alpacas, and guinea pigs. Bananas were cultivated and hybridized in the same period in Papua New Guinea. In Mesoamerica, wild teosinte was domesticated to maize by 4000 BC. Cotton was domesticated in Peru by 3600 BC. Camels were domesticated late, perhaps around 3000 BC.
Sorghum bicolor, commonly called sorghum () and also known as great millet, durra, jowari, or milo, is a grass species cultivated for its grain, which is used for food for humans, animal feed, and ethanol production. Sorghum originated in Africa, and is now cultivated widely in tropical and subtropical regions. Sorghum is the world's fifth-most important cereal crop after rice, wheat, maize, and barley. "S. bicolor" is typically an annual, but some cultivars are perennial. It grows in clumps that may reach over 4 m high. The grain is small, ranging from 2 to 4 mm in diameter. Sweet sorghums are sorghum cultivars that are primarily grown for forage, syrup production, and ethanol; they are taller than those grown for grain.
Internal migration in the People's Republic of China is one of the most extensive in the world according to the International Labour Organization. In fact, research done by Kam Wing Chan of the University of Washington suggests that "In the 30 years since 1979, China's urban population has grown by about 440 million to 622 million in 2009. Of the 440 million increase, about 340 million was attributable to net migration and urban reclassification. Even if only half of that increase was migration, the volume of rural-urban migration in such a short period is likely the largest in human history." Migrants in China are commonly members of a floating population, which refers primarily to migrants in China without local household registration status through the Chinese Hukou system. In general, rural-urban migrant workers are most excluded from local educational resources, citywide social welfare programs and many jobs because of their lack of hukou status. Migrant workers are not necessarily rural workers; they can simply be people living in urban areas with rural household registration.
China is the most populated country in the world and its national population density (137/km) is similar to those of Switzerland and the Czech Republic. The overall population density of China conceals major regional variations, the western and northern part have a few million people, while eastern half has about 1.3 billion. The vast majority of China's population lives near the east in major cities.
In the 11 provinces, special municipalities, and autonomous regions along the southeast coast, population density was 320.6 people per km.
The People's Republic of China (PRC) officially recognizes 56 distinct ethnic groups, the largest of which are Han, who constitute 91.51% of the total population in 2010. Ethnic minorities constitute 8.49% or 113.8 million of China's population in 2010. During the past decades ethnic minorities have experienced higher growth rates than the majority Han population, because they are not under the one-child policy. Their proportion of the population in China has grown from 6.1% in 1953, to 8.04% in 1990, 8.41% in 2000, and 8.49% in 2010. Large ethnic minorities (data according to the 2000 census) include the Zhuang (16 million, 1.28%), Manchu (10 million, 0.84%), Uyghur (9 million, 0.78%), Hui (9 million, 0.71%), Miao (8 million, 0.71%), Yi (7 million, 0.61%), Tujia (5.75 million, 0.63%), Mongols (5 million, 0.46%), Tibetan (5 million, 0.43%), Buyei (3 million, 0.23%), and Korean (2 million, 0.15%).
China has the longest combined land border in the world, measuring from the mouth of the Yalu River to the Gulf of Tonkin. China borders 14 nations, more than any other country except Russia, which also borders 14. China extends across much of East Asia, bordering Vietnam, Laos, and Myanmar (Burma) in Southeast Asia; India, Bhutan, Nepal, Afghanistan, and Pakistan in South Asia; Tajikistan, Kyrgyzstan and Kazakhstan in Central Asia; and Russia, Mongolia, and North Korea in Inner Asia and Northeast Asia. Additionally, China shares maritime boundaries with South Korea, Japan, Vietnam, and the Philippines.
In 2014, 181.5 million hectares of genetically modified crops were planted in 28 countries. Half of all GM crops planted were genetically modified soybeans, either for herbicide tolerance or insect resistance. Eleven countries grew modified soybean, with the USA, Brazil and Argentina accounting for 90% of the total hectarage. Of the 111 hectares of soybean grown worldwide in 2014, 82% was genetically modified in some way. Seventeen countries grew a total of 55.2 million hectares of genetically modified maize and fifteen grew 23.9 hectares of genetically modified cotton. Nine million hectares of genetically modified canola was grown with 8 million of those in Canada. Other GM crops grown in 2014 include Alfalfa (862 000 ha), sugar beet (494 000 ha) and papaya (7 475 ha). In Bangladesh a genetically modified eggplant was grown commercially for the first time on 12ha.
Agriculture, farming, and fishing form the primary sector of industry of the Japanese economy together with the Japanese mining industry, but together they account for only 1.3% of gross national product. Only 20% of Japan's land is suitable for cultivation, and the agricultural economy is highly subsidized.
Tōhoku was traditionally considered the granary of Japan because it supplied Sendai and the Tokyo-Yokohama market with rice and other farming commodities. Tōhoku provided 20 percent of the nation's rice crop. The climate, however, is harsher than in other parts of Honshū due to the stronger effect of the Siberian High, and permits only one crop a year on paddy fields.
The agricultural sector continues to dominate Kenya's economy, although only 15 percent of Kenya's total land area has sufficient fertility and rainfall to be farmed, and only 7 or 8 percent can be classified as first-class land. In 2006 almost 75 percent of working Kenyans made their living on the land, compared with 80 percent in 1980. About one-half of total agricultural output is non-marketed subsistence production. Agriculture is the second largest contributor to Kenya's gross domestic product (GDP), after the service sector. In 2005 agriculture, including forestry and fishing, accounted for about 24 percent of GDP, as well as for 18 percent of wage employment and 50 percent of revenue from exports. The principal cash crops are tea, horticultural produce, and coffee; horticultural produce and tea are the main growth sectors and the two most valuable of all of Kenya's exports. In 2005 horticulture accounted for 23 percent and tea for 22 percent of total export earnings. Coffee has declined in importance with depressed world prices, accounting for just 5 percent of export receipts in 2005. The production of major food staples such as corn is subject to sharp weather-related fluctuations. Production downturns periodically necessitate food aid—for example, in 2004 aid for 1.8 million people⎯because of one of Kenya's intermittent droughts. However, the expansion of credit to the agricultural sector has enabled farmers to better deal with the large risk of agriculture based on rainfall and the dramatic fluctuations of the prices of agricultural products.

In South America, a phenomenon known as the El Nino Oscillation Cycle, between floods and drought on the Pacific Coast has made as much as a 35% difference in Global yields of wheat and grain.
An international effort is under way to improve sorghum farming. The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) has improved sorghum using traditional genetic improvement and integrated genetic and natural resources management practices. New varieties of sorghum from ICRISAT has now resulted in India producing 7 tons per hectare. Some 194 improved cultivars are now planted worldwide. In India, increases in sorghum productivity resulting from improved cultivars have freed up six million hectares of land, enabling farmers to diversify into high-income cash crops and boost their livelihoods. Sorghum is used primarily as poultry feed, and secondarily as cattle feed and in brewing applications.
Cotton is China's most important fiber crop. The crop is grown on the North China Plain and in the middle and lower reaches of the Yangtze River Valley. In the 1970s domestic output did not meet demand, and significant quantities of raw cotton were imported. Production expanded dramatically in the early 1980s to reach a record 6 million tons in 1984. Although production declined to 4.2 million tons in 1985, China was still by far the largest cotton producer in the world. In the 1980s raw cotton imports ceased, and China became a major exporter of cotton.
Wheat has traditionally been the main crop in north China, a considerably drier region than south China. The winter wheat crop accounts for nearly 90 percent of China's total production. Spring wheat is grown mainly in the eastern portion of Inner Mongolia and the northeastern provinces. Other important grain crops include corn, sorghum, and millet. These are usually dryland crops. Since the late 1960s, irrigation has been greatly expanded, but water remains an important limiting factor. Compared with the south, soils in the north are generally better; however, because of the shorter growing season and colder, drier climate, yields per cultivated hectare tend to be lower and irrigation less extensive. Labor is not as abundant in the north as in the south, but cropping patterns tend to require less labor, and mechanization (especially of plowing) is more advanced.
The rural population of the Northeast is heavily concentrated in the warmer southern part of the area, where very warm to hot summer weather permits crops such as maize and millet to be grown with high yields. Soybeans and flax are also very important, as are wheat and barley. The region possesses large flocks of sheep, and pigs are abundant in the more densely settled southern part. The northern half of Heilongjiang is so cold and poorly drained that agriculture is almost impossible; however, the Amur River provides very rich fishing prospects, and sheep are even more abundant than in southern Heilongjiang.
In Cantonese cuisine, it is categorized as a tong sui or sweet soup, hence the Chinese name. The soup is usually thin in texture, but potent in taste. The recipe is simple, consisting of boiling the sweet potato for a long time with rock candy and ginger. Sweet potato is one of the most commonly found and abundant vegetables grown in China. With its simple recipe and large crop supply, sweet potato soup is one of the most accessible and affordable tong sui in the region.
