Graduate programs are available in the physiological, genetic, morphological, and environmental aspects of the production and utilization of horticultural crops.
A Graduate Record Examination (aptitude) is required before admission. A qualifying examination, which must be completed by the second semester in residence, will be required for all graduate students. For detailed information, see hort.unl.edu/.
Master of Science Degree.
Students intending to prepare for professional careers in horticulture may select a course of study under Option I, which includes the requirement of a thesis that contains results of original research. Students wishing to pursue an Option II masters degree must receive separate Horticulture Graduate Committee approval. For approval, the student must work with a major adviser and submit to the Graduate Committee the following items: list of the student’s committee, list of major and minor courses and the student’s project and plan. The requirements for admission to Candidacy and for the thesis are those of the Graduate College.
Horticulture also offers a specialization in Public Horticulture Administration. Most students will be expected to pursue an Option II masters degree although an Option I is possible. The program of studies includes required courses in business or communications, a project or thesis and an internship.
Horticulture also participates in the following interdepartmental areas of specialization for the master of science degree: environmental studies and water resources planning and management. Interested students should look under those areas for details of the program requirements.
A doctor of philosophy degree in horticulture is available.
The following may be used as a part of course work in constituting a major in horticulture: STAT 801, 802, 901, 902; AGRO 815, 914, 932, 966.
