Soybean Variety Tests in Tennessee 2023

Abstract

All soybean variety trials were conducted in each of the physiographic regions of the state. Tests were conducted at Northeast Tennessee (Greeneville), East Tennessee (Knoxville), Middle Tennessee (Spring Hill), Highland Rim (Springfield), Milan (Milan), and West Tennessee (Jackson) AgResearch and Education Centers (REC). Entries were divided into the following tests based on relative maturity: MG-3 (relative maturity 3.0-3.9), MG-4E (relative maturity 4.0– 4.5), MG-4L (relative maturity: 4.6-4.9), and MG-5 (relative maturity: 5.0-5.9). Each test was treated using conventional herbicides to provide a head-to-head comparison across herbicide tolerances. Duplicate plantings of all tests were made at the Milan and Highland Rim AgResearch and Education Center for performance testing with and without irrigation.
