Horticultural Science

 

Courses

Course requirements and recommendations for the Master of Horticultural Science are as follows:

  • A minimum of twenty (20) hours must be at the 500-700 level.
  • At least four (4) but no more than six (6) hours of HS 693 (Master’s Supervised Research) are required.
  • Two (2) credits of HS 601 (Seminar Techniques and Technology) are required.
  • Up to twelve (12) hours of 400-level courses can be taken as part of the MHS program; however, only six (6) hours of Horticultural Science 400-level courses are allowed.
  • Students are encouraged, but not required, to fulfill four (4) credits of the Horticultural Science core course requirement (HS701-707, HS 717).
  • Non-thesis Master’s Examination (HS 690) and Non-thesis Master’s Continuous Registration (HS 688 and HS 689) may NOT be used to satisfy credit hour requirements.

Students are allowed, even encouraged, to take courses from departments other than Horticultural Science. Horticulture is one area of a broad range of interconnected fields including soil science, plant biology, crop science, entomology, plant pathology, statistics, agricultural economics, agricultural engineering, and agricultural education.

When possible, we encourage MHS Online and Distance Education students to take courses on-campus for one semester, ideally during the Fall semester, when they can take HS 601 along with other incoming graduate students. The on-campus experience enables Online and Distance Education students to get to know their faculty advisors and committee members, interact with other graduate students and faculty in the department, and enhance the overall graduate experience.

Graduate Courses in Horticultural Science

The Horticultural Science Program offers a number of online horticulture courses. These may be taken as part of a certificate or degree program, or by non-degree-seeking students on a course-by-course basis. For those interested in taking individual courses without enrolling in a degree or certificate program, you must first enroll as a Post-Baccalaureate Studies (PBS) student.

Below is a partial list of applicable courses offered online. To reveal a course description, click the course in the list below. To view the most up-to-date course listings, please visit the Registration and Records website. Please note that not all courses are offered every semester, and may be cancelled due to low student enrollment. Not all courses listed in the NC State Course Catalog can be offered online.

HS 532 - Introduction to Permaculture

Units: 3

Permaculture means "permanent culture," and ..."is the conscious design and maintenance of cultivated ecosystems that have the diversity, stability, and resilience of a natural ecosystem." [Bill Mollison] This course will explore a design/thinking methodology that seeks to provide our essential physical needs, food, water, shelter, energy, etc., while doing so in an environmentally friendly, sustainable manner. This course is restricted to upper level undergraduate, graduate, or matriculated continuing education students. STUDENTS MAY NOT RECEIVE CREDIT FOR BOTH HS 432 AND HS 532.

Offered in Fall and Summer
