Planting Guide · June 2025 · 5 min read
Grain sorghum uses 30% less water than corn and thrives in heat, making it an excellent rotational crop for dryland farms and drought-prone regions. Proper planting technique sets the stage for competitive yields.
Wait until soil temperatures reach a consistent 60–65°F at a 2-inch depth before planting—cold soils cause poor emergence and seedling disease. Plant at a depth of 1 to 1.5 inches in 30-inch rows at a seeding rate of 50,000–70,000 seeds per acre for dryland and up to 90,000 under irrigation. Sorghum's small seed size demands precise depth control and firm seed-to-soil contact.
Choose hybrids matched to your maturity zone and end use—early-maturing hybrids (95–105 days) suit northern areas, while full-season hybrids (110–120 days) maximize yield potential in the southern Plains. Evaluate standability ratings, as sorghum is prone to lodging in late-season storms. Consider grain color and tannin content if you are targeting specific feed or ethanol markets.
Grain sorghum is traded at roughly 95–100% of the corn price on a per-bushel basis at most elevators, though premiums exist for food-grade white and waxy sorghum. Forward contracting before planting locks in a margin and eliminates basis risk. Check with local elevators about sorghum acceptance—not all facilities handle it, so confirm delivery options and drying capabilities before committing acreage.
