This data was collected and published by University of Georgia's Statewide Variety Testing program from 2016-2019. It consists of experimental (non-regulated) and commercially-released soybean germplasm entered by seed companies and public institutions. Tests were conducted at 7 university-owned farms throughout Georgia, and include environments from the lower Coastal Plain to the southern Appalachians. Locations include Blairsville, Rome, Griffin, Athens (Watkinsville), Midville, Plains and Tifton. Four locations hosted dryland tests in addition to irrigated tests from 2016-2018. In 2019, dryland testing was discontinued in favor of another irrigated environment including all varieties. The number of years a variety was tested varies since their inclusion is determined by the respective test participant. 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. Ultra-late soybean plantings following corn harvest are part of this data set. Their economic viability is limited to the Coastal Plain region of Georgia, South Carolina, and perhaps Alabama. Varieties of maturity groups 5-8 all flower and mature similarly in that environment, and observed yields do not correlate to typical main-season plantings of those same varieties.
