Optimal Soybean Planting Window in Oklahoma

Plant late April through early May (soil temperature ≥ 13 °C / 55 °F at 2-inch depth). Key points:

• After last spring freeze (mid-April in most of OK).
• Early planting maximizes vegetative nodes before flowering.
• Avoid planting into cold, wet soils—risk of seedling disease and poor emergence.
• Maturity Group 3–5 varieties suit Oklahoma’s latitude.
