Plant Sciences at Oregon State University

Injecting bacteria into plant

At Oregon State University, students have the opportunity to study many aspects of plants—from landscape design to plants’ use in medicine, food, and fiber. Instead of following a standard plant science curriculum, OSU’s interdisciplinary programs touch on plants from the molecular level all the way to larger ecosystems.

Plant science students are prepared for jobs in agriculture, plant breeding, or forest or rangeland management.  

Courses in the plant sciences are offered under many different course descriptors by four departments within the College of Agricultural Sciences. Please click the button below to search for courses:

Please note that some courses may be listed under different descriptors (cross-listed); students would select whichever descriptor is most appropriate for their major.  

Animal and Rangeland Sciences

Rangeland makes up over 40% of the world’s land. Our rangeland science graduates work to improve and manage these lands for agriculture, recreation and community use.

Botany and Plant Pathology

Botanists and plant pathologists are called on to understand plants and plant diseases. Our students create knowledge surrounding plants and their function. 

Crop and Soil Sciences

People working in crop production, insect science, and soil science know that improvements to cropping systems are key to feeding our growing world. Crop and soil science graduates are ready to face food production issues in the 21st century.

Forest Ecosystems and Society

How humans interact with the environment and natural resources provides opportunities to learn about safe, sustainable stewardship. Our graduates look at human impacts on all facets of ecosystems, from wildlife habitats to urban areas.

Forest Engineering, Resources & Management

Caring for our forests and our forest ecosystems are at the heart of Oregon State’s forestry programs. Our students learn effective techniques for managing forests, leading forest operations, or understanding the processes that shape our forests. 


Securing safe, sustainable food sources and landscapes is a global and local challenge. Our graduates show how plants can improve people’s lives and livelihoods.
