Types of Plant Crops
Types of Plant CropsUnit 2Food GroupsExamine the items in front
of you.
Work with the other members of the class to put the items into
six groups of like foods. Food GroupsWhat makes the items in each
group alike?
What might these groups represent? where have we seen this
before?
What might we call each group?
Types of Plant CropsThe important field and horticultural crops
of North America can be divided into seven categories:Grain
CropsSugar and Oil CropsFiber CropsVegetable, Fruit and Nut
CropsForage CropsOrnamental and Turf CropsOther Crops
Grain CropsGrain Crops include plants grown for their edible
seeds but do not include horticultural crops.Grain crops provide
many important foods including the cereal grains. Cereal grain is
the seed of grass type plants grown for food and animal feed.
Exapmles: rice, corn, wheat, oats, barley, rye, and sorghum.
Sugar CropsProduced as a sweetenerSugar crops are used as a
source of sucrose. Sucrose is commonly used as table sugar or as a
sweetener in foods and beverages.It is a carbohydrate that provides
energy for the human body. The major sugar crops are sugar cane and
sugar beets.
Oil CropsGrown for their vegetable oil.Oil crops are plants
grown for the vegetable oil contained in their seeds and fruit.The
seeds of about 40 crops are used to make oil. Soybeans, corn, and
cotton are the most common oil crops.Other oil seeds include
sunflowers and peanuts.Fiber CropFiber crops are grown for the
fiber produced in their fruit, leaves, or stems. Fibers are tiny,
threadlike structures used in making cloth and paper. Cotton is the
major crop grown for fiber.Flax is also grown for fiber. It is the
subject of considerable research because of its potential in making
paper.VegetablesOlericulture - Vegetables are a commodity both
fresh and processed. California is the leader in both fresh and
processed vegetables in the U.S.Vegetables are grown on 1% of the
total cropland in the U.S. This amount has been relatively stable
for the past 25 years. However, the production of vegetables has
increased.The increase in production on virtually the same amount
of land is the result of increased technology and more efficient
production practices.
Fruit and NutPomologyIn the 1993, 3.5 million acres of the U.S.
were involved in fruit and nut production.Fruit production utilizes
land unusable by other crops. Fruit growing is a popular but
labor-intensive industry.Hundreds of thousands of people are
employed in fruit and nut production jobs.The U.S. is one of the
worlds top producers of fruit and nuts. Ten percent of the worlds
apples, pears, plums, and prunes, 20 percent of the worlds peaches,
and 25 percent of the worlds citrus fruit are produced in the
U.S.
Forage CropForage is plant material (mainly plant leaves and
stems) eaten by grazing livestock.
Historically, the term forage has meant only plants eaten by the
animals directly as pasture, crop residue, or immature cereal
crops, but it is also used more loosely to include similar plants
cut for fodder and carried to the animals, especially as hay or
silage.
Ornamental and Turf CropsPlants used for their ascetics
(beauty), such as landscaping, interiorscaping, lawns, golf
courses, etc.
