Graduate Program Fact Sheet
Crop Science

The Department of Crop and Soil Science has a dynamic research community, bolstered by our graduate students, dedicated to using innovative methods to expand our basic and applied knowledge of field crops, cropping systems, soils, agricultural watersheds, and crop-related entomology. Many academic disciplines are represented; crop physiology and metabolism, crop production and management, agro ecology & sustainability, ecophysiology, plant breeding and genetics, small farms, weed science, seed science & technology, soil science, water science, entomology, integrated pest management, biological control, plant nutrition, organic agriculture, and waste management.

Crop Science | M.S., PhD

1. Agronomy, M.A., M.S., PhD
This major focuses on the principles and practices of crop physiology, production and field management. It includes many disciplines, sustainable cropping systems, seed science, weed science, pest management, nutrient management and water management. It prepares students to be future agronomist leaders.

2. Entomology, M.A., M.S., PhD
This interdisciplinary major involves many faculty from across campus, comprising areas relating to: Aquatic & Riparian Ecology, Pollinator Conservation, Integrated Pest Management & Applied Entomology, Temporal and Spatial Patterns In Large Species Assemblages, Ecology and Evolution of Plant-insect Interactions.

3. Plant Breeding and Genetics, M.A., M.S., PhD
This major embodies the Land Grant mission of integrated research, teaching and extension in the context of cultivar development and fundamental genetics. It spans a wide range of sciences from classical plant breeding approaches to gene manipulation at the molecular level. Breeders regularly cooperate with pathologists, entomologists, soil scientists, physiologists, food scientists, genomicists and molecular biologists.


Graduate Students

Graduate Student Support

  • Assistantships to support new students are typically associated with external grants or contracts to individual faculty.
  • Tuition is provided by the department for certain grants from Oregon commodity groups. Tuition is waived for graduate students employed as teaching assistants.
  • The department and University also award several graduate fellowships and scholarships to outstanding students. For more information see the Graduate School’s Financing Your Education website at
  • The Coalition of Graduate Employees (CGE) represents the interests and rights of Oregon State University’s graduate employees through the bargaining and maintenance of a fair working contract. CGE strives to create a community of graduate employees empowered to advocate for collective issues.
  • Graduate students in Crop and Soil Science regularly organize social activities and community interactions. The Crop and Soil Science Graduate Student Committee provides support and information to students as needed.
