  • Associated with different major cultures
  • 2. "Root" Crops - White or Irish potato (not a
    root), sweet potato, cassava (manioc or tapioca)
  • 3. Sugar producers - sugar cane, sugar beet
  • 4. Legumes - common bean, soybean
  • 5. Tropical tree crops - coconut, banana

3
Wheat
  • The most widely cultivated plant in the world.
  • Early varieties parched to make gruel or beer
  • Natural hybridization, chromosome doubling --gt
    modern wheat
  • Brought to Mexico in 1529
  • U.S., Canada, and Argentina among worlds great
    producers

4
Rice
  • Limited distribution, but feeds more people
  • Introduced to Carolinas in 1647
  • Used for food, beers wines
  • Produce starch rice powder
  • Hulls used for fuel, building materials, and
    making chemicals for
  • plastic manufacture
  • Straw used

5
Maize (Indian corn)
  • A major animal food
  • Was the most widely grown plant in America
  • Center of Native American life
  • Europe did not embrace it.
  • U.S. is 1st in production, Argentina 2nd, China
    3rd
  • Extremely wide uses

6
Potato
  • 2000 B.C. in America Europe in 1570
  • Began to be common in Europe in 1700s

Sweet potato
  • Origination tropical Americas Pacific islands

  • Extensively grown in Africa Asia
  • Provides 50 more calories than white potato, but
    less protein
  • Major start in US came when grown as slave food

Manioc
  • Tropics of both hemispheres
  • Africa from Brazil - 16th century
  • World production 110 million tons
  • Boiled or roasted or made into meal
  • Tapioca pudding is from manioc

Growing processing

Sugar cane
  • Domestication in New Guinea or Indonesia
  • Europe learned of it from Alexander the Great

  • Napoleon encouraged growth in France
  • Came to U.S. in late 1800s
  • Sugar content has been increased from 2 to 20

12
Legumes
  • Highest of all plant food types in protein
  • Amino acids complement those in cereals
  • Highest consumption in India Latin America also
    high
  • US produces 60 of worlds soybeans
  • 2/5s of crop exported - thus most important crop
    in world trade
  • Nitrogen fixing bacteria associated with roots
  • Toxic members of the family

13
Banana
  • Perennial herb - stem is leaf stalks
  • Originated in SE Asia
  • Reference to it in India from 500 B.C.
  • To Europe 2000 years ago (Alexander)
  • Americas in 1516
  • 1871 - railroad built - banana plantings made to
    provide freight
  • Nutritive value close to white potato, but more
    carbs are in the form of sugar
  • 37 million tons produced annually - only 15
    enters world trade

14
Coconut
  • Palm family Carnuba wax to rattan to dates and
    coconuts
  • Tree known in India since 1000 B.C.
  • Tree bears 50 to 100 coconuts/year
  • Meat is dried making copra - oil extracted
    (60-70 by weight)
  • Oil most important product - makes soaps,
    margarine (though less now)
  • Residue coconut cake fed to livestock

15
U.S. Fruit culture
  • Nurseries in NY NE in 1640s
