Training, Other Qualifications

A bachelor's degree in plant biology is sufficient for some jobs in product development or for assisting in applied research, but a master's or doctoral degree (PhD) is generally required for basic research or for jobs directing applied research. A PhD in agricultural science or plant biology is usually needed for college teaching and for advancement to senior research positions as well. Degrees in related sciences, such as molecular biology, genetics, chemistry, or biochemistry may also qualify people for many plant science jobs.

The American Society of Agronomy certifies sub-specialists, such as crop advisers. These certifications require at least a bachelor's degree and several years of work experience. Applicants must also pass designated examinations and agree to adhere to a code of ethics. Each certification is maintained through continuing education.

Education and Training

A bachelor's degree is the minimum requirement for plant science jobs. Students preparing for careers as plant scientists should take college courses in plant pathology, entomology, plant physiology, and biochemistry, among others.

To conduct basic research or to advance to jobs directing applied research, a master's or doctoral degree is required. Advanced degree programs in plant science include classroom and fieldwork, laboratory research, and a thesis or dissertation based on independent research.

Other Qualifications

Plant scientists should be able to work independently or as part of a team and be able to communicate clearly and concisely, both orally and in writing. Most of these scientists also need an understanding of basic business principles, the ability to apply statistical techniques, and the ability to use computers to analyze data and to control biological and chemical processing.

Nature of the Work

Plant scientists plays an important role in maintaining the nation's food supply by ensuring agricultural productivity and food safety. These scientists study farm crops and develop ways to improve their quantity and quality. They look for ways to improve crop yield with less labor, control pests and weeds more safely and effectively, and to conserve soil and water. Some plant scientists look for ways to use agricultural products for fuels.

Plant scientists study plants in order to help producers of food, animal feed, and fiber crops to feed a growing population and conserve natural resources. These scientists not only help increase productivity, but also study ways to improve the nutritional value of crops and the quality of seed, often through biotechnology. Some plant scientists study the breeding, physiology, and management of crops and use genetic engineering to develop crops that are resistant to pests and to drought. They also develop new technologies to control or eliminate pests and prevent their spread in ways appropriate to the specific environment.

Work Environment

Plant scientists work in a variety of environments. Those involved in basic research seek to understand the biological and chemical processes by which crops grow, such as determining the role of a particular gene in plant growth. Scientists involved in applied research use this knowledge to discover mechanisms to improve the quality, quantity, or safety of agricultural products. Other plant scientists manage or administer research and development programs, or manage marketing or production operations in companies that produce agricultural chemicals, seeds, and machinery. Some plant scientists are consultants to business firms, private clients, or government.

Plant scientists involved in management or basic research tend to work regular hours in offices and laboratories. The work environment for those engaged in applied research or product development varies, depending on specialty and on type of employer. Many plant scientists also spend time outdoors conducting research on farms and agricultural research stations.

On the Job

  • Communicate research and project results to other professionals and the public, or teach related courses, seminars, or workshops.
  • Provide information and recommendations to farmers and other landowners regarding ways in which they can best use land and promote plant growth.
  • Conduct experiments to develop new or improved varieties of field crops, focusing on characteristics such as yield, quality, disease resistance, nutritional value, or adaptation to specific soils or climates.
  • Develop new or improved methods and products for controlling and eliminating weeds, crop diseases, and insect pests.
  • Conduct research to determine best methods of planting, spraying, cultivating, harvesting, storing, processing, or transporting horticultural products.
  • Study insect distribution and habitat and recommend methods to prevent importation and spread of injurious species.
  • Identify and classify species of insects and allied forms, such as mites and spiders.
  • Conduct experiments regarding causes of bee diseases, and factors affecting yields of nectar pollen.

Science Fair Project Idea
To be able to live on Mars, humans need breathable air, clean water, and nutritious food. Spacesuits can provide oxygen to breathe, ice on Mars can be a source of water, but how could we get nutritious food? Today's astronauts bring food with them. But a manned trip to Mars would require food that was either successfully grown in space or on Mars, as taking the extra weight of food for such a long time—it takes 6–9 months one way—is just too costly. In this project, you will… Read more
Science Fair Project Idea
Have you ever seen a (non-carnivorous) plant eat? Probably not! Plants do not get the energy they need from food, but from the sunlight! In a process called photosynthesis, plants convert light energy, water, and carbon dioxide into oxygen and sugar. They can then use the sugar as an energy source to fuel their growth. Scientists have found an easy way to measure the rate of photosynthesis in plants. The procedure is called the floating leaf disk assay. In this plant biology project, you can… Read more

What do plants need to grow? Most of us would answer that they need light, air, water, and soil. But by using a process called hydroponics, you can grow plants without soil! How does it work? Try this project and see for yourself! Read more
Science Fair Project Idea
Water is a valuable resource, and water shortages are a serious problem in many parts of the world. The problem can be made worse by people who waste water; for example, by watering a garden or using sprinklers on their lawn (or a farmer taking care of an entire field) when it has rained recently or the soil is already moist. How can you help conserve water and prevent such waste? One way is to build an electronic soil moisture sensor. This project will show you how to build a circuit that… Read more

Fuzzy things are often cute, but not when that fuzziness is mold on your strawberry—yuck! Companies look for natural, plant-based ways to protect the berries from mold when they are in the store, waiting for you to purchase them. Would washing them in aloe vera juice protect strawberries from mold? Do this project and find out! Read more
Science Fair Project Idea
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of gravity) and roots go down (in the same direction as the force of gravity). In this project, you will construct simple devices that hold several germinating seeds, which allow you to watch how growing rootlets respond as you rotate the devices, effectively altering… Read more
