Plant Sciences Major
Roll up your sleeves and grow with us.
Embark on an in-depth exploration of plant life. Make the world a better place through a hands-on understanding of plants for food, fiber, medicine, and fuel. Science, academic, government, industry, and entrepreneurial careers await.
A small green world for the big blue planet.
Penn State Plant Sciences has world-renowned faculty, on-campus greenhouses, a plethora of laboratories, and thousands of acres of research farms where you can pursue your passion. But what’s really special is not how big it is, but how small. Faculty and staff put student needs first. And the facilities are truly unique in their proximity and accessibility.
Feeding more people on less land. Sustainability. Food deserts. Our small world is making a huge impact. Penn State Plant Sciences research and outreach are making a real difference, all over the world. Join us today as we tackle tomorrow’s biggest challenges.
Plant Sciences is the right major for if you’re:
- seeking hands-on learning in greenhouse spaces, labs, research and teaching farms, a student farm, and hydroponics and aquaponics systems
- interested in sustainable food, fuel, flower, and fiber systems with consideration for climate impacts
- curious about growing and developing plants for better human nutrition, greater insect and disease resistance, and medical or aesthetic qualities
See the University Bulletin for details on program requirements, suggested academic plan, and more.
One major. Five paths. Infinite destinations.
Agroecology option
Research innovative ways to produce crops and other plants for food and fibers with a constant eye on sustainability. This path leads to opportunities in alternative/niche food production in roles within government, institutions, and industry, and opens doors for the highly entrepreneurial.
Example courses
- Integrated Pest Management
- Intro to Agroecology
- Principles and Practices of Organic Agriculture
Crop Production option
Develop practical, science-based skills for producing crops and managing soil. Grads enjoy careers as farm managers, leaders in ag-related industries, and roles in government.
Example courses
- Crop Scouting
- Forage Crop Management
- Soil Composition and Physical Properties
Horticulture option
Dig into the science of producing crops and ornamentals for food, fiber, fuel, and beauty. Grads run specialty agricultural operations like greenhouses, orchards, public gardens, and farms, and enjoy leadership in the plant science industry, government, and academia.
Example courses
- Greenhouse Management
- Vegetable Crops
- Hydroponics and Aquaponics
Plant Genetics and Biotechnology option
Dive into a combination of basic science and technology-based classes. This option teaches theoretical and practical skills of plant genetic manipulation needed in plant biotechnology, plant breeding, and genome research. It can help prepare students for employment in industry or academia.
Example courses
- Molecular Biology of the Gene
- Physiology of Agricultural Crops
- Plant Tissue Culture and Biotechnology
Plant Science option
Take a hard-science approach to cultivating plants for human nutrition, greater insect and disease resistance, and beauty. Grads work in plant science research and industry or continue on to graduate studies.
Example courses
- Plant Microbe Interactions
- Plant Nutrition
