China is the world's largest producer of potatoes, [1] generating more than 22 percent of global potato production. The potato is the only crop that can be grown in all regions of China, although cultivation predominantly takes place in the northern and southern regions of the country.
The potato was introduced to China from the New World during the late Ming dynasty, but only started being promoted as a staple food during the 20th century. [2] [3]
Potato production in China had already been on the rise in the 1960s and early 1970s, following the Great Chinese Famine. [4] A dramatic surge in the production of potatoes in 1993 against a slump in European output propelled China to the forefront of the international potato production scene. The tremendous surge of potato production during the 1990s has been credited to technological advancements. [4] 21st-century production of potatoes in China has fallen considerably though, largely due to growth sites becoming less suitable and hence diminishing the sustainability of potato cultivation, alongside the increasing prioritisation of other crops and produce over potatoes. [4] Efforts from 2004 onwards started to focus on the organic production of potatoes; the first organic potato enterprise originated in Heilongjiang, while Wuchuan County, which has good water, weather and a culture of using organic fertilisers, is the largest of all the organic potato producers in China. [5]
In a speech in 2015, China's vice minister of agriculture Yu Xinrong said "Hunger breeds discontentment. … The development of the potato industry and the consumption of potatoes as a staple food is an important step in China’s agricultural development". [6] Since 2015 government policy promotes the use of the potato as a staple food, [7] using potato flour as a substitute for wheat flower and promoting the use of potato in traditional dishes. [3]

The potato is a tuber crop which has high nutritional value. It has protein, calcium and vitamin C. One potato of medium size contains 50 percent of the daily vitamin C needs of an adult. When boiled, its protein content is reported to be more than that of maize, with double the calcium content. [10]
The potato is the only crop that is plantable in all regions of China, although the country has four main potato-planting regions: [5] North China (Heilongjiang, Jilin, Liaoning, Inner Mongolia, Hebei, Shanxi, Shaanxi, Ningxia, Gansu, Qinghai and Xinjiang), which makes up around 47 percent of the total planting area in the country; Central China (Liaoning, Hebei, Shanxi, Shaanxi, Hubei, Hunan, Henan, Shandong, Jiangsu, Zhejiang, Anhui and Jiangxi), contributing towards 7 percent of the total planting area; South China (Guangxi, Guangdong, Hainan, Fujian and Taiwan), 8 percent; and Southwest China (Yunnan, Guizhou, Sichuan, Chongqing, Tibet, Hubei and Hunan), 38 percent. [5]
Based on data by the Food and Agriculture Organization (FAO), the actual planted area of potatoes in 2006 was 4,900,000 hectares (12,000,000 acres), or about 26.14 percent of the total global planted area. [5] The total production of potatoes in China was over 70,000,000 tonnes (77,000,000 tons), or more than 22 percent of the global potato production, [5] making China the largest potato producer in the world. [1] [11] [12] However, the average yield of potatoes in China was 14.35 tons/ha, compared to the global mean of 16.74 tons/ha. [5]
Over the past decade, the planted area of potatoes in China has been growing because of the important role of potatoes in poverty reduction and food security, [13] not to mention the greater economic returns of selling potatoes vis-a-vis other crops. The total planted area in 2006 was 5,020,000 hectares (12,400,000 acres), notwithstanding the planted areas in Shandong, Henan, Zhejiang and Guangxi. Additionally, the planted area in the winter-fallow land parcels in certain subtropical and tropical regions of the country has been growing by the year due to the increased profitability of selling potatoes during the winter; for instance, the planted area of potatoes in the Guangxi Autonomous Region rose from 30,000 hectares (74,000 acres) to 130,000 hectares (320,000 acres) from around 2001 to 2006. [5]
Apart from sub-par seed qualities and economic expectations, pests and fungal diseases, including late blight, have devastatingly limited the production of potatoes in China; [14] this, however, has prompted intense research on ways to combat them. [15]
Potatoes have historically not been an integral part of the Chinese diet. [16] In Chinese cuisine, potatoes are used as a vegetable and not as staple carbs. [17]
Potatoes in China are also increasingly being used to make potato crisps and french fries, [18] especially with the country's burgeoning fast food and processed food industries. [19]
The name given to the potato differs by region. In Northeast China they are called 土豆; tudou, in Northern China they are called 山药蛋; shānyào dàn, in Northwest China they are called 洋芋; yángyù, in Zhejiang and Jiangsu they are called 番芋; fānyù, in Cantonese they are called 薯仔; syu4 zai2 and in Taiwan, Malaysia and Singapore 馬鈴薯; 马铃薯; mǎlíngshǔ is most commonly used. [20]
The potato is a starchy tuberous vegetable native to the Americas that is consumed as a staple food in many parts of the world. Potatoes are underground tubers of the plant Solanum tuberosum, a perennial in the nightshade family Solanaceae.
Sesame is a plant in the genus Sesamum, also called benne. Numerous wild relatives occur in Africa and a smaller number in India. It is widely naturalized in tropical regions around the world and is cultivated for its edible seeds, which grow in pods. World production in 2018 was 6 million tonnes, with Sudan, Myanmar, and India as the largest producers.
What Mustard Is
Kale, also called leaf cabbage, belongs to a group of cabbage cultivars primarily grown for their edible leaves; it has also been used as an ornamental plant.
Physalis peruviana is a species of plant in the nightshade family (Solanaceae) native to Chile and Peru. Within that region, it is called aguaymanto, uvilla or uchuva, in addition to numerous indigenous and regional names. In English, its common names include Cape gooseberry, goldenberry and Peruvian groundcherry.
Khorasan wheat or Oriental wheat is a tetraploid wheat species. The grain is twice the size of modern-day wheat, and has a rich, nutty flavor.
The asparagus bean is a legume cultivated for its edible green pods containing immature seeds, like the green bean. It is also known as yardlong bean, pea bean, long-podded cowpea, Chinese long bean, snake bean, bodi, and bora. Despite the common name of "yardlong", the pods are actually only about half a yard long, so the subspecies name sesquipedalis is a more accurate approximation.
Basella alba is an edible perennial vine in the family Basellaceae. It is found in tropical Asia and Africa where it is widely used as a leaf vegetable. It is native to the Indian subcontinent, Southeast Asia and New Guinea. It is naturalized in China, tropical Africa, Brazil, Belize, Colombia, the West Indies, Fiji and French Polynesia.
Brassica juncea, commonly mustard greens, brown mustard, Chinese mustard, Indian mustard, Korean green mustard, leaf mustard, Oriental mustard and vegetable mustard, is a species of mustard plant.
Yam is the common name for some plant species in the genus Dioscorea that form edible tubers.
Food biodiversity is defined as "the diversity of plants, animals and other organisms used for food, covering the genetic resources within species, between species and provided by ecosystems."
Brosimum alicastrum, commonly known as breadnut, Maya nut or ramon, and many others, is a tree species in the family Moraceae of flowering plants, whose other genera include figs and mulberries.
Vegetables are parts of plants that are consumed by humans or other animals as food. The original meaning is still commonly used and is applied to plants collectively to refer to all edible plant matter, including the flowers, fruits, stems, leaves, roots, and seeds. An alternative definition of the term is applied somewhat arbitrarily, often by culinary and cultural tradition. It may exclude foods derived from some plants that are fruits, flowers, nuts, and cereal grains, but include savoury fruits such as tomatoes and courgettes, flowers such as broccoli, and seeds such as pulses.
Agriculture in Ghana consists of a variety of agricultural products and is an established economic sector, providing employment on a formal and informal basis. It is represented by the Ministry of Food and Agriculture. Ghana produces a variety of crops in various climatic zones which range from dry savanna to wet forest which run in east–west bands across Ghana. Agricultural crops, including yams, grains, cocoa, oil palms, kola nuts, and timber, form the base of agriculture in Ghana's economy. In 2013 agriculture employed 53.6% of the total labor force in Ghana.
Organic farming is practiced around the globe, but the markets for sale are strongest in North America and Europe, while the greatest dedicated area is accounted for by Australia, the greatest number of producers are in India, and the Falkland Islands record the highest share of agricultural land dedicated to organic production.
Poland's agricultural sector is vital for European and Global market because it produces a variety of agricultural, horticultural and animal origin products. The surface area of agricultural land in Poland is 15.4 million ha, which constitutes nearly 50% of the total area of the country.
In North Korea, the cultivation of potatoes is an important aspect to the livelihood of the country's population. The crop was introduced into the country in the early 1800s. Since the famine of the 1990s, a potato revolution has taken place. Over ten years, the area of potato cultivation in North Korea quadrupled to 200,000 hectares and per capita consumption increased from 16 to 60 kilograms per year.
A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs and generally forming a significant proportion of the intake of other nutrients as well. For humans, a staple food of a specific society may be eaten as often as every day or every meal, and most people live on a diet based on just a small variety of food staples. Specific staples vary from place to place, but typically are inexpensive or readily available foods that supply one or more of the macronutrients and micronutrients needed for survival and health: carbohydrates, proteins, fats, minerals, and vitamins. Typical examples include grains, seeds, nuts and root vegetables. Among them, cereals, legumes and tubers account for about 90% of the world's food calorie intake.
Riceberry is a rice variety from Thailand, a cross-breed of jao hom nin and khao dawk mali 105. The variety was created in 2002 by the Rice Science Center, Kasetsart University, Kamphaeng Saen Campus, Nakhon Pathom, Thailand. The outcome is a soft, deep purple whole grain rice.
Nigeria is one of the largest producers of potatoes in Africa. The potato was introduced to the country in the 19th century by Christian missionaries and is largely cultivated in the central region of the country in Plateau State.
China is the world's largest potato producer, accounting for 22% of the global production.
Domestic production has kept pace, making China the world's largest potato grower
