The University of Georgia evaluates short day onion varieties to determine their performance characteristics in standardized growing practices. Variety entries for the trial are submitted by participating seed companies. These trials are conducted at the Vidalia Onion and Vegetable Research Center located in Lyons, GA. There were 52 varieties entered into the 2021–2022 UGA onion variety trial.

This study aimed to determine the effect of biodegradable mulch on Vidalia onion bulb yield in three sweet onion cultivars.

This study looked at the relative availability of sulfur from various soil profile depths by growing onions on raised beds with differing depths to the claypan and varying sulfur content.

This study examined the extent of variability in soil properties across the Vidalia production region and how those differences are related to onion yield and pungency. While soil characteristics, like claypan depth, clearly play a major role in onion productivity and flavor profile, soil series classification alone is not sufficient to describe how soil characteristics influence onion yield and pungency. Further research is needed.

Understanding nitrogen requirements of onions at different growing stages is crucial to adequately manage N fertilizer applications and enhance fertilizer use while minimizing nutrient losses. In this study, the fertilizer N use efficiency of onions was investigated. The application of N fertilizer right after transplant is inefficient; targeting the periods of heavy vegetative growth and bulb initiation was most efficient in providing N fertilizer for onion plants.

The objectives of this study were to quantify the efficiency of field workers in transplanting Vidalia onions at an approximate population of 95,000 seedlings per acre and to verify the consistency of transplanting. The quality of transplanting varied widely among field workers, with issues such as seedlings lying on the ground, partially transplanted seedlings, and multiple seedlings in a single furrow. These inconsistencies can negatively impact plant population and uniformity.

Transplanting is the process in which seedlings are transferred from a specific place where they were sown to the soil where they will develop and produce. This process is an extremely important step in fruit and vegetable production as it helps with the initial establishment of the crop. Mechanical transplanters have emerged as important agricultural machines for farmers, and are designed to automate and optimize the transplanting process.

A soil test is a chemical technique used to determine the status of available nutrients in a soil sample. It is a common method used to predict how soils will react to the addition of lime or fertilizer and calculate how much of each is required for crop production.

The growth and development of sweet corn is affected by accumulated heat units, measured in growing degree days (GDDs). This publication provides South Georgia sweet corn growers with insights into the relationship between temperature and GDD units and the key growth stages of sweet corn. This will help growers make informed decisions about the timing for planting, management practices, irrigation, and harvesting.
