3. A. Define Horticulture and its related fields; • Horticulture originates from Latin hortus= gardening culturea= cultivation • Together they literally translate: “Garden cultivation”

4. Agricultural Plants

5. Divisions of Horticulture

6. Fruit Production Pomology = Fruit Production • Propagation of fruit trees, vines, plants • Harvest of Fruit • Marketing

7. Vegetable Production Olericulture = Vegetable Production • Vegetable Production • Home Gardens • Large Scale Gardens • Harvest • Marketing

8. Floriculture Floriculture= Production of Flowers a. Cut Flowers b. Bedding Plants c. Potted Plants • Marketing • Florists

9. Landscape Horticulture Landscape Construction & Design • Irrigation systems • Plant Installation • Flower Beds • Landscape Design

10. Turf Turf = Ground cover • Turf Farms • Installation • Golf courses • Sport’s fields

11. Arboriculture Arboriculture= Cultivation & Care of trees, shrubs, & Vines • Production • Tree Pruning and Care • As part of landscape Maintenance

12. B. Identify the various roles of plants in everyday life; • Meeting basic human needs • Food • Clothing • Shelter

13. Roles of Plants • Plants are direct or indirect sources of these three needs • Direct Plant Source – Plant or plant products are used by humans • Indirect Plant Source – Plants are used as animal feed and the animals or animal products are used by humans

14. Food • Solid and liquid material we eat • Provides the nutrients we need to grow and live healthy lives • Americans expect their food to be: • Readily available • Wholesome/promote health • Convenient/Easy-to-use

15. Clothing • Includes the garments, accessories and ornaments we ware • Garments are the most important area of clothing • Garments – worn to cover and protect the body and give it a certain appearance • Exe. skirt, jeans, shirt • Accessories - worn to supplement basic clothing • Exe. tie, belt, scarf • Ornaments – Worn for a certain appearance or to represent status • Exe. rings and pins • Clothing made from natural fiber can come from both direct and indirect plant sources. • Direct – Cotton, Flax • Indirect - Wool

16. Shelter • Protect us from the elements and from harm • Our homes and the items that make our homes comfortable • Wood products are widely used in building construction

17. C. Identify agriculturally important plants, and explain their uses; Field Crops • Plants grown in large fields • Used for: • Oil • Fiber • Grain • Similar products • Often grown for their seed, but other parts may be used • Example: corn, wheat, cotton, barley, safflower, soybean

18. C. Identify agriculturally important plants, and explain their uses; Horticultural Crops • Grown for food, comfort, and beauty • In some cases appears to overlap field crops • Ornamental Horticulture • Growing and using plants for their beauty • Includes Floriculture and Landscape Horticulture • Food Crop Horticulture • Growing plants for food • Includes Olericulture (Vegetable Crops) and Pomology (Fruit and Nuts)

19. C. Identify agriculturally important plants, and explain their uses; Forestry • Growing frees and producing wood products • Lumber, paper, plywood, furniture, and similar products • Also includes specialty products like maple syrup, rosin, and oil • Involves Native Forests and Tree Farming

20. D. Describe how horticulture is related to science and technology. Science: • Successful Horticulture is an application of science • Growing plants takes more than just a daily watering • Must understand: • Effects of heat, light, and photosynthesis • Cell division, osmosis, transpiration, etc…

21. Science + Technology + Plant Production = THE HORTICULTURE INDUSTRY

23. Development of Agriculture and Society Plant & Soil Science

24. Civilization In the beginning, Nomads followed herds of animals and gathered food. When they discovered that they could seed grain and harvest it, they no longer needed to follow a food source. This allowed people to live in one place, thus the beginning of civilization.

25. Origins of Grain Wheat = Egypt, Iran, Turkey Corn = Mexico Explorers would bring wheat to North America, and return with corn.

26. Agriculture 250 Years Ago 95% of the US Population Farmed Each Farmer produced enough feed to feed and clothe 3 people Most of the work was done by hand- some animal power was used People used the barter system to exchange goods and services.

27. 250 Years Ago • Families were self-sufficient by producing their own • Tobacco, sugar cane, rice, and cotton • Clothing • Soap • Candles • Medicines • Shoes • Farming Implements

28. Significant Events- 250 Years Ago • 1793- Eli Whitney invented the cotton gin. • The cotton gin helped remove seeds form the short staple of cotton, and the demand for cotton grew. Cotton was used in the US and exported as well!

29. Agriculture 200 Years Ago 92% of the population still farming Each farmer produced enough to feed and clothe four people The barter system was used mostly for trading soap, candles, medicines, and shoes Families were becoming less self-sufficient

30. Significant Events- 200 Years Ago 1831- Cyrus McCormick developed the mechanical reaper. Mechanical reaper was the forerunner of the grain combine and was used for wheat. 1837- John Deere began manufacturing plows. With this invention the fertile ground could be plowed under and cultivated

31. Agriculture 150 Years Ago 90% of the population farmed Each farmer produced enough for five others

32. Significant Events- 150 Years Ago 1855- Michigan and Pennsylvania established the first state agriculture colleges. Justin Morrill a senator from Vermont introduced a bill to provide funds to establish schools to teach practical methods of producing food and fiber. These schools would also be conducting scientific research.

33. Significant Events- 150 Years Ago • 1862- President Lincoln created the first Department of Agriculture. (USDA) • The Morrill Act passed providing land to each state to build a college for common people. The purpose was to teach agriculture and mechanical arts.

34. Significant Events- 150 Years Ago 1869- Transcontinental railroad was completed. 1872- Congress passed the Hatch Act. This allowed states with land grant colleges to establish experiment stations. 1875- The first grain silos were built 1881- Hybrid Corn, which is produced by crossing different varieties was introduced

35. Agriculture 100 Years Ago Only 50% of people farmed Each farmer produced enough for seven others Gasoline tractors were introduced Banks began loaning money to farmers to purchase land and equipment Farm families produced most of their own food and wood, and consumers had more needs.

36. Significant Events- 100 Years Ago 1914- The Smith-Lever Act was passed by congress. 1917- The Smith-Hughes Act was established. This allowed agriculture to be taught in high schools. 1933- The Farm Credit Administration was established 1940- The school milk program was initiated 1947- A general agreement on tariffs and trade was negotiated

37. Agriculture 50 Years Ago • 30% of the US Population was farming • Each farmer produced enough for 11 others • Gas tractor was in general use, horses still outnumbered tractors as the main source of farm power • Banks provided capital to farmers. Farmers tried to avoid borrowing because of massive farm losses and foreclosures in the 20’s and 30’s.

38. Significant Events 50 Years Ago 1959- The mechanical tomato harvester was developed. 1964- The national food stamp program was passed. 1991- More farmers used Integrated Pest Management (IPM) 1993- Passage of the North American Free Trade Agreement (NAFTA)

39. Agriculture Today Less than 2% of US population is involved with production agriculture Each farmer produces enough for 148 others Many gov’t programs are available to help stabilize production and processing, insure supplies, limit soil erosion and regulation. For every dollar produced by agriculture, 6-8 other dollars are generated in a community

40. Significant Events The US supplies ½ of the grain sold on the world market The number of farmers have declined, but related agriculture jobs has increased

42. Introduction to Utah’s Agricultural Crops Mr. Wilson Uintah High School

43. Student Learning Objectives As a result of this lesson, the student will … Objective #1 Appreciate the Diversity of Agriculture Production in Utah. Objective #2 Understand the Scope and Value of Agriculture Production in Utah.
