THE PROGRAM OF STUDIES

Agronomy and Horticulture are two fundamental sciences concerned with feeding, clothing and beautifying the world. They are among the primary sciences associated with genetic engineering to improve the quality of life for humanity. The academic thrust of the department is to ground students firmly in the science of these two disciplines to qualify them for further graduate work or for employment in industry, government, or private enterprise.

The Department of Agronomy and Horticulture offers two degrees:

Agronomy—MS and Horticulture—MS. The department also offers Molecular Biology—MS as an interdepartmental program.

Areas of specialization within the degrees: Crop Science, Soil Science, Horticulture, Developmental Agriculture.

There will usually be an average of eight graduate students pursuing the MS degree. The program is intended to be completed in two calendar years.

Agronomy, Horticulture, Molecular Biology—MS

Agronomy: Agronomy is the science that feeds the world. It is a composite title for issues associated with the major food crops, soils, environmental restoration, reclamation, genetic engineering, Third-World development, etc.

Horticulture: Horticulture is the science of fruit and vegetable production. These food products are finding greater essential use in our diet as scientific knowledge about human needs is defined. Horticulture also finds expression in the beauty of growing plants and in the floral art form.

Molecular Biology: The molecular biology program is a multidepartmental program in the College of Biology and Agriculture that allows students to learn modern procedures and techniques used in research at the molecular level. Students who successfully complete the MS degree in this discipline are fully qualified to compete for a PhD graduate program in the same discipline at another university.

Students should apply to the molecular biology program in the college and designate agronomy or horticulture as the study specialization. Refer to the Molecular Biology section of this catalog for a program description.

Admission and Entry.

Agronomy or Horticulture (MS): baccalaureate degree in agronomy or horticulture or related field.

Molecular Biology (MS): baccalaureate degree in molecular biology or biological or physical science, including one year of general university physics, mathematics equivalent to Math 113, one year of organic chemistry with laboratory, and one year of cell biology and genetics equivalent to Botny-Mcbio-Zool 341 and 342.

Requirements for Degree.

Thesis Option (30 hours): minimum 24 course work hours plus 6 thesis hours (AgHrt 699R).

Project Option (36 hours): minimum 30 course work hours plus 6 project hours (AgHrt 698R).

Molecular Biology: additional specific requirements of Chem 481, 582, 586; Stat 337 or 501; Mcbio 351, 425, 441, 442, and 642 or Zool 526.

FINANCIAL ASSISTANCE

Financial assistance is available for these programs through the Department of Agronomy and Horticulture. The department has from four to seven assistantships. There are also funds for tuition offsets granted through the department from the Office of Graduate Studies. Other financial aid is available through the university.

RESOURCES AND OPPORTUNITIES

Agriculture Station. The station encompasses several sites, all of which support research in basic and applied agriculture. Station facilities include: an 837-acre farm in Spanish Fork, Utah, a few miles south of Provo, with 80 acres of orchards, crop research plots, a 440-cow dairy, a 60-head beef herd, and a 70-sow swine unit; the 9,388-acre BYU Skaggs Research Ranch near Malta, Idaho; and several livestock project areas in north Provo, among them the Ellsworth Meat and Livestock Center and poultry, sheep, and horse projects. At these facilities research can be conducted on soils and on field, forage, and horticultural crops.

Ezra Taft Benson Agriculture and Food Institute. The major objective of the institute is to raise the quality of life among the people of the world through improved nutrition and enlightened agricultural practices. Emphasis is placed on teaching and training students who wish to work in foreign countries and on training people from those countries in agriculture and food science practices that can be used to improve life. Research to improve agricultural practices, family nutrition, and appropriate technology is encouraged.

M. L. Bean Life Science Museum. Exhibits and collections of biological specimens are housed in the M. L. Bean Life Science Museum. The exhibits include habitat studies of local as well as exotic plant and animal species and a large and valuable collection of trophies from North America, Africa, and Asia.

USDA Forest Service Shrub Science Laboratory. Housed on the BYU campus, this laboratory supports one of the finest research programs on native shrubs in the world. Here eleven PhD research scientists with adjunct faculty appointments work with BYU faculty members and graduate students. Laboratories, greenhouses, and gardens on campus and around the state support studies on desert shrubs.

Other Laboratory and Field Resources. On the Provo campus are an arboretum, a small animal vivarium, a tissue culture room, and several environmental chambers. Laboratory facilities include gas chromatographs-mass spectrometers, isotope ratio mass spectrometers, transmission and scanning electron microscopes, ultra centrifuges, visible ultraviolet and infrared spectrophotometers, gas chromatographs, high-performance liquid chromatographs, infrared gas analyzers, atomic absorption spectroscopy, and many other items. Besides excellent greenhouse facilities and environmental chambers, the department has an experimental research area at the BYU Agriculture Station and a horticulture study area where all-American vegetable and flower selections are grown.

Faculty and graduate students are currently engaged in a number of significant and interesting research projects, funded both internally and externally. Some of these are: mineral uptake by plants; ecology and seed physiology; photosynthetic rate and water-use efficiency in plants; plant breeding and molecular genetics; forage research; and environmental science.
