Jeffery Iles, Chair of Department
For undergraduate curriculum in horticulture leading to the Bachelor of Science degree, see Horticulture, Curriculum.
To meet the educational needs of a student population with interests ranging from landscape design/installation to fruit and vegetable production to golf course construction and management, considerable flexibility is built into the horticulture curriculum. And the diversity of interests and need for flexibility is reflected in our impressive array of horticulture courses.
The Department of Horticulture offers nine options within the horticulture major; (1) Environmental Horticulture, (2) Greenhouse Production and Management, (3) Fruit & Vegetable Production and Management, (4) Horticultural Communications and Public Education, (5) Nursery Crops Production and Landscape Management, (6) Planting Design/Installation, (7) Public Garden Management and Administration, (8) Science, and (9) Turfgrass Management. Students considering graduate degrees should participate in the Science option.
Graduates possess the technical knowledge and skills to become professional horticulturists. They understand plant growth and development and are familiar with cultural and management principles for a wide assortment of horticultural crops. They are able to work and communicate effectively with fellow horticultural professionals and with ordinary citizens who share an interest in horticulture. Graduates also understand the ethical and environmental dimensions of problems and issues facing horticultural professionals.
A degree in horticulture opens the door to employment opportunities with production nurseries, seed companies, interior landscaping firms, greenhouses, garden centers, conservatories, landscape design/installation firms, public gardens and arboreta, orchards and vineyards, food processing companies, vegetable farms, golf courses, sports fields, sod production companies and lawn care businesses. Several industries closely related to horticulture provide employment opportunities in the areas of sales, management, and communication. Opportunities also exist for careers in research, teaching, and business after obtaining advanced training in graduate school.
Undergraduate students have the option of selecting a secondary major in one of several interdepartmental programs including, seed science, agricultural education, environmental studies, or international agriculture (see Index).
The Department of Horticulture offers work for a minor in horticulture that is earned by taking Hort 221 plus at least 12 credits in horticulture at the 200 level or above, with 6 of those credits at the 300 level or above.
Visit our departmental website at www.hort.iastate.edu
The department offers work for graduate degrees (M.S. and Ph.D.) for students who major in horticulture. Under special circumstances a nonthesis master's degree is available through the master of agriculture program. The department also participates in interdepartmental majors such as plant physiology, genetics, and molecular, cellular, and developmental biology (see Index)
Graduate students majoring in horticulture usually take minor course work in agronomy, botany (cytology, morphology, or physiology), biochemistry, chemistry, entomology, food science and human nutrition, genetics, plant pathology, or statistics. There is no uniform foreign language requirement for the master of science or doctor of philosophy degree.
Graduates possess a broad understanding of horticulture and the allied plant sciences. They are able to communicate effectively with members of the scientific community, industry groups, and other interested citizens. They are experienced in conducting research and communicating the results from that research. They are capable of addressing and solving complex problems that confront the many horticultural, agricultural and plant science professions. They also understand the ethical, legal, social, and environmental issues associated with modern agricultural/horticultural practices.
Courses open for nonmajor graduate credit: 332, 351, 351L, 422, 433, 434, 435, 442, 451, 453, 461, 471, 493.
