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 University

These 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.

Trial reports are typically released in January–March of the year following harvest. For Soybeansvariety selection, the most recent year’s report is the most relevant data source.
