Vidalia Onion and Vegetable

Our Work and Purpose

The Vidalia Onion and Vegetable Research Center is located between Reidsville and Lyons in Toombs County on Highways 178 and 147. The facility is administered in five buildings on 3 acres of land owned by the University of Georgia College of Agricultural and Environmental Sciences.

Two 11-acre tracts on a long-term lease from the Georgia Forestry Commission provide researchers and staff land to conduct studies and educational demonstrations.

The center was established in 1999 primarily to provide research on Vidalia onions, and 6-7 acres of research plots have been devoted to this crop every year.

Researchers have developed a new pumpkin variety here that will enable south Georgia farmers to grow pumpkins commercially for the first time. In addition, fertility studies and variety trials have been conducted in corn, squash, cucumbers and pumpkins. Blackberries, strawberries, carrots, Brassica crops, garlic, shallots and artichokes have also been studied here, along with no-till and organic vegetable production and composting demonstrations.

Combining data collection and analysis with plant pathology, precision agriculture and robotics, the UGA team will build a photographic library of the foliar symptoms caused by onion diseases and other physiological disorders, feed them into the AI software, and use machine learning to identify the diseases based on pattern and color recognition from the images.

UGA uses AI, robotics to improve Georgia’s Vidalia sweet onion crop
A multidisciplinary team of UGA researchers aims to enhance the competitiveness of Vidalia onion growers in Georgia by providing them with the ability to confidently detect onion diseases early, enabling them to make management decisions on their crop at a critical time. These abilities, researchers say, should result in increased yield and quality of marketable onions and an overall increase in efficiency and productivity.
