Matthew Vann

Associate Professor

Tobacco Production & Management


Williams Hall 4212


A native of Lafayette County, Florida (which is located in the historic Florida Tobacco Belt), Dr. Vann greatly understands the value of tobacco to the family farm.  Growing up he enjoyed working on his family’s Century Pioneer Farm, and spent many summers working the neighboring tobacco and watermelon fields in his community.  After high school, he enrolled at the University of Florida – graduating in 2009 with a degree in Environmental Management in Agriculture and Natural Resources and a double minor in Plant Science and Soil Science.  He completed his M.S. (2011) and Ph.D. (2015) in the Crop and Soil Sciences Department at North Carolina State University where his research and education focuses were to the agronomic management of flue-cured tobacco.  In 2015, Dr. Vann was appointed to the Dr. William K. Collins Tobacco Agronomist Position in Research, Teaching, and Extension Endowment.  His responsibilities include teaching tobacco production courses in both the two (CS 116) and four year (CS 216) programs at NC State University, advising M.S. and Ph.D. level graduate students, supporting the efforts of Cooperative Extension Agents with tobacco responsibilities, directing Good Agricultural Practice (GAP) training for North Carolina tobacco farmers, and providing timely Extension information to allied industry.


Dr. Vann serves as a primary author of bi-weekly tobacco production updates entitled “From the Field-Agronomy Notes”, which are available during the production season through the NC State Tobacco Portal.  He is a member of the American Society of Agronomy, Crop Science Society of America, Soil Science Society of American, American Society for Horticultural Sciences, and the Weed Science Society of North Carolina.  In addition, he serves an author or co-author of five chapters of the annual NC State Flue-Cured Tobacco Production Guide, two chapters of the Burley and Dark Tobacco Production Guide, and three tables in the annual North Carolina Agricultural Chemicals Manual.

He conducts applied research in areas related to variety evaluation, plant nutrition, crop physiology, greenhouse production, weed management, sucker control, organic tobacco production, and pesticide residue quantification.  Dr. Vann utilizes research facilities located in Whiteville (Border Belt Tobacco Research Station), Kinston (Cunningham Research Station), Rocky Mount (Upper Coastal Plain Research Station), Oxford (Oxford Tobacco Research Station), Clayton (Central Crops Research Station), Laurel Springs (Upper Mountain Research Station), and Waynesville (Mountain Research Station).  His research efforts are focused on flue-cured, burley, and cigar wrapper tobacco production.

Dr. Vann also participates in the Cooperative Centre for Scientific Research Relative to Tobacco (CORESTA), which is based in Paris, France.  To date he has authored or co-authored more than 30 conference abstracts and currently serves as the Secretary to the Agrochemical Residue Field Trial Task Force.  The efforts of the task force serve to generate the data necessary for the establishment of Guidance Residue Limits as they pertain to Crop Protection Agent residues detected in/on cured leaf.
