Colorado State University

What you'll study

The Plant Sciences degree at Colorado State University provides a foundation in plant biology, ecology and agricultural systems alongside applied training in crop management and production. First-year study emphasises core courses in biology, chemistry, mathematics and communication, while later years focus on specialised plant topics.

• Core scientific foundations: plant physiology, genetics, ecology, soil science and plant pathology.
• Applied agriculture and production: crop production systems, weed science, integrated pest management, irrigation and nutrient management.
• Horticulture and controlled-environment systems: greenhouse production, nursery management, post-harvest handling and urban horticulture.
• Research and analytical skills: laboratory methods, field experiment design, data analysis and statistics.
• Practical experience: supervised field labs, greenhouse practicals, internships and opportunities for undergraduate research with faculty.
• Electives and specialisations: students can choose courses in plant breeding and genetics, sustainable agriculture, agroecology, or business and policy electives relevant to agriculture and natural resources.

The programme typically culminates in advanced coursework and a capstone experience or research project that integrates scientific knowledge with real-world plant production or research challenges.

Entry requirements

Applicants should hold a secondary school qualification equivalent to a US high school diploma, with a strong foundation in science and mathematics. Typical preparation includes coursework in biology, chemistry and algebra or higher-level maths. Colorado State University considers the overall academic record, preparation for the intended major and extracurricular experience.

• Recommended subjects: biology, chemistry, mathematics and, where available, agricultural science or environmental science.
• International applicants: must present equivalent secondary credentials and demonstrate English language proficiency through recognised tests or institutional waivers.
• Transfer students: can apply with college-level coursework in sciences and general education; articulation guides and academic advising help map prior credits into the Plant Sciences curriculum.
• Additional considerations: relevant work or volunteer experience in horticulture, farming, research labs or conservation can strengthen an application.

Career prospects

Graduates with a Bachelor’s in Plant Sciences move into a wide range of roles across agriculture, horticulture, environmental management and the private sector. The degree prepares students for both technical and managerial positions as well as for further study.

• Agronomic or crop production specialist working with growers or seed companies.
• Plant breeder, propagation specialist or greenhouse/production manager in horticulture and nursery industries.
• Extension educator or technical advisor delivering outreach and applied research to farmers and communities.
• Laboratory or field technician in plant pathology, entomology or soil science research.
• Roles in conservation, restoration ecology and native plant management for public agencies and NGOs.
• Sales, product development or technical support for agricultural inputs, equipment and biotechnology firms.
• Progression to graduate study (MSc/PhD) in plant sciences, crop science, ecology, plant pathology or related fields, and teacher certification pathways for secondary education.

Why study at Colorado State University

Colorado State University offers Plant Sciences students access to a strong agricultural college environment with extensive hands-on learning. The programme benefits from on-campus greenhouses, research farms and field laboratories that support teaching and undergraduate research.

• Practical, experiential learning: frequent field and greenhouse practicals, internship placements and opportunities to participate in faculty-led research projects.
• Research and extension links: collaboration with campus research units and regional extension services connects students to applied projects and industry partners across Colorado and beyond.
• Location advantages: proximity to diverse cropping systems and varied ecosystems provides exposure to dryland agriculture, irrigated production and mountain-western plant issues.
• Career support: dedicated advising, career services and strong industry contacts help students find internships, seasonal work and permanent positions after graduation.

Together these elements prepare graduates to enter the workforce with practical skills and scientific knowledge or to continue into advanced study in plant and agricultural sciences.
