Crop and Soil Science

M.S. and Ph.D. degrees require original research presented in a thesis. The M.Ag. degree does not require a thesis; its emphasis is on broad training in several fields relating to agriculture or soil science.

Students select thesis topics and programs of study in consultation with a graduate committee chaired by their graduate advisor. Research topics and programs of study are highly personalized and tailored to each student’s specific skills, interests, and career goals.

Areas of Specialization

Areas of study leading to advanced degrees in Crop Science include biotechnology, cereal breeding and genetics, cereal chemistry, crop physiology, crop production, forage and pasture management, hop breeding and genetics, new crops, potato production, breeding and genetics, seed physiology, seed production, seed technology and quality, weed science, and entomology.

M.S. Degree Requirements

  • Forty-five credits of graduate courses, including up to 12 credits for the M.S. thesis, or 6 credits for a project for the non-thesis M.S. degree.
  • Completion of an original research project and presentation of a thesis; or for the non-thesis option, completion of a problem-solving project.
  • For the M.S. degree with thesis, participation in teaching is required. Students with no previous teaching experience are required to participate in teaching for a minimum of one term. This requirement may be fulfilled as a course (CSS 509) taken for credit.

Ph.D. Degree Requirements

  • Completion of a graduate course program and the Ph.D. thesis, requiring about four years of full-time graduate study.
  • Completion of an original research project and presentation of a thesis.
  • Participation in teaching. Students with no previous teaching experience are required to participate in teaching in the crop science program for a minimum of one term. This requirement may be fulfilled as a course (CSS 509) taken for credit.
