Ten Crops that Feed the World
Corn/Maize (1/10)
Annual Production: 784,786,580 tons
Yield: 49.7 tons/hectare
No other grain is produced in such quantities worldwide as maize, or corn as it is called in North America. Industrialized countries largely use it as livestock feed. In sub-Saharan Africa, maize is a staple food for an estimated 50 percent of the population.
Maize is an important source of carbohydrates, protein, iron, vitamin B, and minerals. Untreated conventional maize, however, can lead to malnutrition and protein deficiency. (Photo: Reuters)

Rice (2/10)
Annual Production: 651,742,616 tons
Yield: 41.5 tons/hectare
Rice is the second most consumed cereal grain. It provides more than one fifth of the calories consumed worldwide by humans. A properly cared for rice plant can produce rice for 20 years. On average, farmers need 2,000 liters of water to produce one kilogram of rice, reports the UN.

Wheat (3/10)
Annual production: 607,045,683 tons
Yield: 27.9 tons/hectare
Wheat is the third most produced cereal crop after rice, but covers more land area worldwide than any other crop. Unlike rice, wheat is more widespread globally. It tolerates windswept areas too dry and too cold for rice and corn.
About one in every 100 to 200 people is allergic to gluten, a protein found in wheat. (Photo: Reuters)

Potatoes (4/10)
Annual production: 321,736,483 tons
Yield: 16.6 tons/hectare
Potatoes are the world's number one non-grain food commodity. Unlike major cereals, potatoes are not a globally traded commodity and thus prices are not influenced by the vagaries of international markets. (Photo: Reuters)

Cassava (5/10)
Annual production: 228,138,068 tons
Yields: 12.2 tons/hectare
An important staple crop in parts of Africa and South America, cassava roots contain more starch than most other food crops. Cassava also thrives better in poor soils than any other major food plant and is drought resistant. Cassava roots and leaves contain toxic levels of cyanogenic glucosides. Cooking and pounding makes the plant edible.(Photo: Reuters)

Soybeans (6/10)
Annual Production: 216,144,262 tons
Yield: 22.7 tons/hectare
Soybeans contain significant amounts of all the amino acids essential for humans. Protein and oil account for 60 percent of
the weight of a dried soybean. Soybeans also improve soil fertility by adding nitrogen from the atmosphere, a benefit for farmers in developing countries where fertilizers are too expensive. (Photo: Reuters)

Sweet Potatoes (7/10)
Annual production: 126,299,661 tons
Yield: 13.9 tons/hectare
Sweet potatoes are native to tropical South America, but China is now the world's biggest producer. They can be grown in poor soils with little fertilizer and have few natural enemies making pesticides unnecessary. Sweet potatoes contain more fiber content, complex carbohydrates, protein, vitamins A and C, iron, and calcium than most vegetables. (Photo: Reuters)

Sorghum (8/10)
Annual production: 64,589,459 tons
Yield: 1.5 tons/hectare
Sorghum is the fifth most important cereal crop worldwide. It is drought and heat tolerant and thus an important crop in arid regions where major cereals do not produce sufficient yields. Consumption of sorghum, however, has decreased considerably in many African countries, especially in urban areas. (Photo: Reuters)

Yams (9/10)
Annual production: 51,948,149 tons
Yields: 11.2 tons/hectare
West and Central Africa account for more than 90 percent of world yam production. Yam cultivation and harvesting are more labor intensive than for other starchy staples. Yams are the first crop to be harvested in the year and the Yams Festival is a popular holiday in several African countries.(Photo: James Foster, licensed under Creative Commons Attribution ShareAlike 2.5)

Plantain (10/10)
Annual production: 34,444,795 tons
Yield: 6.3 tons/hectare
Plantains are a starchy, low in sugar variety of bananas that are cooked before eating. They are major food staples in East and West Africa. Since the 1970s, plantain yields have been declining due to soil degradation, pests, poor crop husbandry, and drought. (Photo: Reuters)
