Ph.D. in Plant and Soil Science

The Doctoral of Philosophy (Ph.D.) degree in Plant and Soil Science derives its principal impetus from the strong commitment to research of the Department's faculty and research staff. The Ph.D. program is designed to meet specific career objectives of the students. This degree focuses on research, which must reflect the student's original thinking and should demonstrate the ability of independent investigation.

About This Program

In the Plant and Soil Science Ph.D. program, students may specialize in one of the following areas: Plant Breeding, Tissue Culture, Biotechnology, Plant Genetics and Cytogenetics, Molecular Genetics, Crop Production, Sustainable Agriculture, Seed Science and technology, Plant Physiology, Plant Pathology, Horticulture, Forestry, Entomology, Environmental Science, Remote Sensing, Soil Chemistry, Soil Fertility, Soil Microbiology or Soil (Genesis, Morphology and Conservation). In addition to selected courses in the department, students can take courses in related subjects such as such as Biology, Chemistry, Biochemistry, Mathematics, Computer Science, Food Science and Agricultural Economics. In addition, a minor is offered in Remote Sensing and Geographic Information Systems. Access to faculty, multiple lab spaces, and agricultural research fields and spaces provide the tools necessary for student a seeking this doctorate. These assets give every chance to excel and refine all the skills and knowledge our students have gained.

A student in the Ph.D. degree program will be knowledgeable about their chosen area of specialization in the Plant and Soil Science Graduate Program in the Department of Biological and Environmental Sciences. This knowledge will be acquired primarily through satisfactory completion of required coursework, attendance at Departmental seminars, and research. Additionally, our students will develop the ability to learn independently by determining, finding, and using necessary resources. Our students will also develop the ability to make decisions and judgments based on their knowledge. Furthermore, the student will be capable of addressing a research problem/project through a series of independent, sustained, logical experiments, the writing of scholarly research that reflects and is a direct result of research conducted by the graduate student during his or her matriculation, bring his or her work to a satisfactory conclusion in the form of a Ph.D. dissertation. Finally, it is expected that the dissertation will be of publishable quality and, as a minimum, will be communicated through at least two oral presentation or poster session at a scientific meeting.
