UGA Variety Testing Corn Grain Evaluations 2014-2019

This data was collected and published by University of Georgia's Statewide Variety Testing program from 2014-2019. It consists of experimental (non-regulated) and commercially-released corn hybrids entered by seed companies. Tests were conducted at 6 university-owned farms each year throughout Georgia, and include environments from the lower Coastal Plain to the southern Appalachians. Locations include Blairsville, Rome, Griffin or Athens (Watkinsville), Midville, Plains and Tifton. At Rome and Tifton, both irrigated and dryland tests were performed. Not all hybrids appear in all environments in a given year. The number of years a hybrid was tested varies since their inclusion is determined by the respective seed company. Prior to 2019, separate randomizations were created at each location for short (RM 115 or less) vs mid (RM 116+) maturity hybrids. As a result, not all hybrids occurring in an environment can be directly compared. Soil types differed between locations. Initial soil fertility for P and K is categorized, and actual rates of applied fertilizer are listed. Applied fertilizer rates were chosen to support a yield goal slightly above the maximum observed at the site in previous years.
