Majors and Programs

Undergraduate Degree Programs

You can earn a bachelor’s degree in the following fields of study. Listed below each are the program options available to you at the Corvallis campus.

Agricultural Business ManagementAgricultural Business Management

The curriculum blends course work in agricultural economics, business, agricultural sciences, computer science, arts, and humanities so graduates can respond to the unique challenges and opportunities in agribusiness vocations.

Agricultural Sciences

The program provides maximum flexibility in designing and structuring a course of study to meet students' individual needs. General agriculture should be seriously considered by students desiring programs of study not currently available in any other agricultural department (such as those involving a minor in communications, recreation, General Agricultureor environmental studies in agriculture); students wishing to pursue two or more areas of specialization; students preparing for leadership positions in agriculture that require excellent communication and leadership skills as well as breadth of agricultural background; or students who have not selected a departmental major in the College of Agricultural Sciences but know they are interested in an agricultural career.

Areas you can emphasize within this program are general agriculture, leadership and communication, and teacher preparation.

Animal SciencesAnimal Sciences

Programs provide up-to-date information on methods of rearing domestic livestock, poultry, and horses, and producing meat, milk, eggs, wool, and other animal products. In addition, students become prepared for advanced studiesin animal sciences, veterinary medicine and education.

  • animal management
  • preveterinary medicine


Bioresource Research

Bio EngineeringBioresource research students acquire research experience and broadly based knowledge in interdisciplinary fields of agricultural, environmental, food, health, and forest sciences. Many become industrial or academic research professionals in science, while others will enter graduate and professional schools in the life sciences or become secondary school science teachers.

  • animal reproduction and development
  • applied genetics
  • bioproducts and bioenergy
  • biotechnology
  • climate and biosystems modeling
  • environmental chemistry
  • food quality
  • genomics/bioinformatics
  • pest biology and management
  • plant growth and development
  • sustainable ecosystems
  • toxicology
  • water resources


This undergraduate program is designed for students who wish to emphasize studies in plant biology and receive a B.S. degree in botany. Students may also have an undergraduate major in biology and emphasize botany courses in their upper division work.

  • Botanical Research
  • Fungal Biology
  • Plant Ecology and Systematics
  • Plant Molecular Genetics and Biotechnology
  • Pre-Professional Teaching Botany

Crop and Soil Science

Crop and Soil ScienceCrop science involves growing, protecting, developing and improving plants that supply the world's food, livestock feed, fuels, seed-based industrial raw materials, soil and watershed protection, lawns, turf and wildlife crops. Soil science is an applied science that builds upon a strong foundation in biology, chemistry, geology and physics. Students who like science and the challenge of solving problems can do it all in soil science.

  • crop management
  • ecosystem analysis and policy
  • plant breeding and genetics
  • seed systems
  • soil resource management
  • soil science

Ecological Engineering Undergraduate Program

The Bachelor of Science (BS) in Ecological Engineering degree program offered through the Colleges of Agricultural Science and Engineering is a new degree program that is the first of its kind nationally at the undergraduate level. The undergraduate Ecological Engineering degree program requires completion of 192 credit hours. The Ecological Engineering program is accredited by the Engineering Accreditation Commission of ABET.

Environmental Economics and PolicyEnvironmental Economics

The curriculum develops skills in agricultural economics, resource economics, economic development, marine economics, international agricultural trade and related fields. This program provides flexibility to meet a wide variety of educational and career goals.

Fisheries and Wildlife Sciences

The undergraduate curriculum is composed of core courses as well as specializations. The core covers the educational Fish and Wildlifefoundation of fish and wildlife conservation, and the specializations provide the student with an opportunity to build a curriculum to meet specific goals. Sample specializations include forest wildlife management, stream ecology, fish and wildlife law enforcement, marine fisheries, aquaculture, conservation education and extension, fisheries business, human dimensions of resource management, conservative biology and many others.

Food Science and Technology

Food ScienceFood science and technology involves the chemistry and engineering to deliver safe, convenient food products from the farm to the market. The program integrates principles and concepts in the physical, biological, and engineering sciences, and applies them to the scientific and technological aspects of food processing. The role of the food scientist is to successfully integrate these disciplines to assure an abundant, high quality, and nutritious food supply.

  • food science
  • fermentation science
  • enology and viticulture


HorticultureHorticulture involves the production, genetic improvement, storage and marketing of fruits, nuts, vegetables, flowers and vegetable crops along with the design, construction and management of landscape plantings such as parks, gardens, golf courses, restoration projects and sports fields.

Rangeland Science

Rangeland ResourcesThis is one of the natural resources professions important to the social, economic and political development of Oregon, the nation and the world. It is based upon ecological principles and is concerned with the restoration, improvement, conservation and use of rangelands. Concepts of integrated land use are included in the curriculum. The program includes a balance among soil, domestic animal, wildlife, ecology and other biological sciences.

Sustainability Double Degree:

Once you've chosen a primary degree program, you can receive a second bachelor's degree in sustainability by completing an additional 36 credits.
