Page 2: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Common Core/ Next Generation Science Standards Addressed

CCSS.ELA-Literacy.RST.9-10.4 - Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 9–10 texts and topics.

CCSS.ELA-Literacy.RST.9-10.5 - Analyze the structure of the relationships among concepts in a text, including relationships among key terms (e.g., force, friction, reaction force, energy).

CCSS.ELA-Literacy.RST.9-10.6 - Analyze the author’s purpose in providing an explanation, describing a procedure, or discussing an experiment in a text, defining the question the author seeks to

address.

Bell Work

1. What products can you get from trees other than wood?2. What crops do you seen grown around your home

town?3. Other than decoration what uses can you think of for

flowers?4. Name as many grain crops as you can?

Plant Science and its three major areas

Plant Science – the study of structure, functions, growth, and protection of plants.

3 areas of plant science: Field Crops Horticultural Crops Forest Crops

Page 9: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Field Crops

Plants grown in large fields used for oil, fiber, grain, and similar products.

They are often grown for their seed, such as corn and wheat.

Agronomy: the specialized area of plant science that deals with field crops.

Page 10: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Horticultural Crops

Plants grown for food, comfort, and beauty.

In some cases, horticulture overlaps with field crops.

However, in most cases, horticultural crops are not grown on vast areas of land.

Page 11: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Forest crops – production of trees

Forestry includes growing trees and the production of wood, food, and medicinal products.

Some forest crops are grown on tree farms or cultured forests.

Careful thought and planning goes into the production of forest crops on tree farms.

Page 12: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Common field crops and their uses

Grain crops Sugar and oil crops Fiber crops

Page 13: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Grain Crops

Plants grown for their edible seeds, does not include horticultural crops.

Cereal grain is the seed of grass type plants grown for food and animal feed.

Grain and cereal crops include rice, corn, wheat, oats, barley, rye, and sorghum.

Page 14: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Sugar and Oil Crops

Are produced for two important commodities:sweeteners vegetable oil.

Page 15: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Sugar Crops – source of sucrose

Sucrose: 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.

Page 16: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Oil Crops

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.

Page 17: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Fiber Crops

Are grown for the fiber produced in their fruit, leaves, or stems.

Fibers are tiny, threadlike structures used in making cloth and paper.

Crops grown for fiber include cotton and flax

Page 18: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Cotton and Flax

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.

Page 19: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Horticultural crops and their uses

Two major areas of Horticulture: Ornamental Food crop production

Page 20: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Ornamental Horticulture

Growing and using plants for their beauty.

It includes: floriculture landscape horticulture.

Page 21: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Floriculture

The production and use of plants for their flowers and foliage.

Roses and chrysanthemums are examples of floriculture crops.

Page 22: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Landscape Horticulture

Growing and using plants to make the outdoor environment more appealing.

It includes shrubs, lawns, and flowering plants.

Interiorscaping: using plants indoors to create an attractive environment.

Offices and malls often use plants to increase the appeal of their surroundings.

Page 23: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Food crop horticulture

Growing plants for food. Is divided into two areas:

Olericulture Pomology

Page 24: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Olericulture

The science of producing vegetable crops like tomatoes, peppers, asparagus, and broccoli.

It is carried out on a large scale in warmer areas of the country like South Florida, Texas, and California.

Page 25: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Pomology

The science of producing fruits and nuts.

It includes growing, harvesting, and marketing the crop.

Common pomology crops include oranges, lemons, apples, cherries, pecans, and walnuts.

Page 26: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Forestry

The art and science of managing forests to yield maximum forest products and services.

It is the managing of forest lands to meet human needs.

Page 27: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Forest Products - Crown

The crown of the tree is the upper portion of the tree.

The crown produces such items as fruits and nuts, decorations, and oils.

Page 28: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Forest Products - Trunk

The trunk is the main stem of the tree. It is used in producing lumber and other wood products.

The tree’s bark is also used in producing oils, dyes, and drugs.

The bark of the Pacific Yew is used in making the drug taxol, which holds promise in treating cancer.

Page 29: Unit C 2-4: Basic Principles of Agricultural/Horticultural Science

Forest Products – Stumps/Roots

Tree stumps are used in making veneer wood products.

They are also used in producing turpentine, pine oil, and resin.

Tree roots are used in the production of tea, oil, and turpentine.
