Regional strengths
MG 4 is the dominant maturity for the Upper Southeast and is widely double-cropped behind winter wheat across Tennessee, Kentucky, and northern Arkansas. Pioneer's Enlist E3 trait is well-positioned here for resistant Palmer amaranth control. Frogeye leaf spot resistance is increasingly important — verify per variety.
Regional weaknesses
Charcoal rot can be severe in dry late-summer years on lighter soils in northern Mississippi and western Tennessee — check per-variety charcoal rot tolerance. Double-crop behind wheat compresses the planting window and a slightly shorter MG (4.0–4.4) often outperforms full-season MG 4.5–4.9 in double-crop systems.
Recommended for
- full-season MG 4 systems
- double-crop behind winter wheat
- fields with Palmer amaranth pressure (Enlist)
Not recommended for
- very late double-crop plantings (after July 1) — consider shorter MG
Where this data comes from
Soybeans variety trials in Upper Southeast
Independent · Public UniversityThese results come from independent university variety trials — not seed company marketing materials. Variety entries, planting dates, and harvest measurements are controlled by the trial program. Land-grant universities publish full results annually.
