The Graduate Faculty


Students may specialize in crop production and marketing, integrated crop management, plant genetics and breeding, horticultural plant physiology, postharvest physiology, plant molecular biology and biotechnology, and horticultural ecology.

Admission Requirements

Scores from the Graduate Record Examinations (GRE), or from a comparable substitute examination accepted by a graduate program and authorized by the dean of the Graduate School, are required for admission. At the discretion of the graduate program officer, a student may be admitted provisionally for graduate study in a program without these scores. Requirements listed here are in addition to general Graduate School requirements stated in the GENERAL INFORMATION section of the Graduate Bulletin.

Prerequisites for admission vary according to the area of specialization, but basic courses in physical sciences, mathematics, biological sciences, communication skills, and social sciences and humanities are required. Students who lack prerequisite courses may be admitted but are required to make up deficiencies without degree credit.

Students with a 2.75 junior/senior average (on a 4.00 scale) and with appropriate course backgrounds will be considered for admission. The best-qualified applicants will be accepted up to the number of spaces that are available for new students.

See for the most current Admission requirements.

Master's Degree Requirements

All M.S. degree candidates must complete at least one graduate course in biometry, at least 2 credits of resident or extension education (HORT 596 or HORT 602), and two seminars (HORT 590). A thesis is required for the M.S. degree.

Doctoral Degree Requirements

The communication requirement for the Ph.D. degree may be satisfied by completing at least 6 graduate credits in an area of communications skills approved by the student's advisory committee.

All Ph.D. candidates must present at least three seminars (HORT 590) for credit and complete at least two graduate courses in statistics or statistical applications. Ph.D. students must take 2 credits of resident or extension education (HORT 596 or HORT 602).

The candidacy examination must be taken within six months after beginning residency.

Within one semester after passing the candidacy examination, the student's doctoral committee, with the thesis adviser in charge, will have the program planning meeting. The purposes of this meeting are to (1) determine the student's strengths and weaknesses in pertinent subject matter areas; (2) guide the student in developing a plan of study; and (3) review and discuss the proposed thesis research.

The comprehensive examination, composed of both written and oral parts, will be given when, in the student's and adviser's opinion, the student is ready for the examination, and when the communication requirements and essentially all courses have been completed.

After the thesis is completed and all other requirements for the Ph.D. have been met, the dean of the Graduate School will schedule the final examination. Normally, three months must elapse between the comprehensive and the final examinations. A major part of the examination will be an oral defense of the thesis.

Student Aid

Fellowships, traineeships, graduate assistantships, and other forms of financial aid are described in the STUDENT AID section of the Graduate Bulletin. Students who wish to compete for fellowships should be sure that their application materials are complete by January 15 for entry the following fall semester.
The following award typically has been available to graduate students in this program:


Available to students studying the nutrition of horticultural crops; stipend equivalent to a half-time assistantship. Apply through the Department of Horticulture.


Graduate courses carry numbers from 500 to 599 and 800 to 899. Advanced undergraduate courses numbered between 400 and 499 may be used to meet some graduate degree requirements when taken by graduate students. Courses below the 400 level may not. A graduate student may register for or audit these courses in order to make up deficiencies or to fill in gaps in previous education but not to meet requirements for an advanced degree.
