All corn hybrid trials were conducted in each of the physiographic regions of the state. Tests were conducted at the Highland Rim (Springfield), East Tennessee (Knoxville), Milan (Milan) and West Tennessee (Jackson) AgResearch and Education Centers.
The early and medium-season tests were also planted at the Agricenter International Research Center in Memphis. Duplicate plantings of the early, medium- and full-season tests were made at the Milan and Highland Rim REC for performance testing with and without irrigation.
The corn hybrids were placed in either the early, medium- or full-season tests based on the maturity as reported by the company providing the hybrid.
