Studies & Degrees in Plant Sciences

Plant sciences is the study of plants, from the genes and cells that control their growth to the crops, forests and green spaces that people manage. It joins plant biology (botany, physiology, genetics, ecology) with applied fields such as crop production, plant breeding, plant pathology and horticulture. Purdue University describes plant scientists as people who study crops and develop ways to improve their quantity and quality, control pests and weeds more safely, and conserve soil and water.

Students combine laboratory work with time outdoors. Purdue University recommends courses in plant pathology, entomology, plant physiology and biochemistry for future plant scientists. McGill University stresses hands-on experience, with an on-campus farm that has crop fields, orchards and greenhouses. Biotechnology is part of the subject too: some plant scientists use genetic engineering to develop crops that resist pests and drought.

Qualifications and levels

  • Bachelor's degree. Plant sciences is offered either as a named degree or as a route inside biology or agriculture. The University of Maryland has a Plant Science major with three concentrations: plant biology, turf and golf course management, and urban forestry. At McGill University, students of the Bachelor of Science (Agricultural and Environmental Sciences) add a 24-credit specialisation in plant biology, plant production or professional agrology. In England, The University of Sheffield and the University of Worcester teach plant biology within three-year biological sciences degrees.
  • Spain. Official bachelor's degrees (grados) have 240 ECTS credits. Plants are studied mainly inside biology and agricultural engineering degrees: the four-year Grado en Biología at the Universidad de Murcia, for example, includes botany, ecology, soil science and plant physiology among its subject areas.
  • Master's degree and PhD. Research careers require postgraduate study. The University of Maryland offers B.S., M.S. and Ph.D. degrees in plant sciences. At McGill University, the M.Sc. in Plant Science is a 45-credit course and research programme set with a supervisor, in areas that include plant breeding, genomics, horticulture and molecular plant pathology. Official master's degrees in Spain have 60, 90 or 120 ECTS credits.
  • Vocational and short courses. Practical horticulture can be studied below degree level. In the United Kingdom, the Royal Horticultural Society offers qualifications at three levels, all designed for part-time study.

Where to study plant sciences

SpainExchange lists 19 active schools for plant sciences. Eight are in the United States and five in the United Kingdom; Spain, Canada, Nigeria, Ethiopia, Australia and Sweden have one each. The list includes Purdue University, the University of Maryland and the University of California, Davis in the United States; The University of Sheffield, The University of Manchester, The University of Edinburgh and the University of Oxford in the United Kingdom; McGill University in Montreal; Uppsala Universitet in Sweden; the University of Melbourne; Obafemi Awolowo University in Nigeria; and the Universidad de Murcia in Spain.

Most of these programmes are taught in English, and international applicants have to prove their level: The University of Sheffield, for example, asks for IELTS 6.5 with a minimum of 6.0 in each component for its biological sciences degree. The biology degree at the Universidad de Murcia is taught in Spanish. When comparing schools, check whether the programme leans towards laboratory biology or towards agriculture and horticulture, what field stations, farms or greenhouses students can use, and whether a placement year or a period abroad is offered; Sheffield lists an optional placement year.

Careers

Plant scientists work in crop research and breeding, seed and food companies, agricultural advisory services, environmental consultancies, botanic gardens, universities and government agencies. According to Purdue University, a bachelor's degree is the minimum requirement for plant science jobs, and a master's or doctoral degree is required to conduct basic research or to direct applied research.

The US Bureau of Labor Statistics groups plant scientists with agricultural and food scientists. It reports 19,900 soil and plant scientists in the United States and projects that overall employment of agricultural and food scientists will grow 6 percent from 2025 to 2035, faster than the average for all occupations. Food manufacturing is the largest employer of this group, with 18 percent of jobs.

Frequently asked questions

Is plant sciences the same as botany?

Botany is the biology of plants. Plant sciences is wider: it adds applied areas such as crop production, plant breeding, plant pathology and horticulture, and at some universities also turf management or urban forestry.

How long does a degree in plant sciences take?

The biological sciences degrees cited here in England take three years, and an official Spanish bachelor's degree has 240 ECTS credits over four years. A master's degree in Spain adds 60, 90 or 120 ECTS credits.

Do I need a master's degree or a PhD?

Not for every job. A bachelor's degree is the minimum for plant science posts, according to Purdue University, but basic research and positions directing applied research require a master's or doctoral degree.

Can I study plant sciences in Spain?

Plant biology is taught inside broader degrees such as biology. The Grado en Biología at the Universidad de Murcia has 240 ECTS credits, is taught in Spanish and covers botany and plant physiology.
