Piper Sudangrass

Untreated Seed
  • Long-established and proven non-BMR variety
  • Upright warm-season summer annual that grows up to 8ft tall; leaves resemble corn
  • Rapid Emergence and early growth; excellent for weed suppression
  • Good forage crop that can be grazed
  • Natural soil fumigant; when tilled under can reduce nematode populations
  • Lower prussic acid poisoning hazard than sorghum-sudangrass
  • Wait to plant until soil is 62°F

Sudangrass

An annual grass with finer stems and higher quality compared to sorghum-sudangrass hybrids & forage sorghums. Sudangrass is coarser than Japanese millet and grows 4’ to 7’ tall.

Best Uses: Hay, grazing, green chop, silage, or baleage. Use multi-cut system or managed grazing for best quality.

Adaptation: Likes hot weather.

Management: Harvest 6” above ground for best regrowth. When harvested early (30”), sudangrass contains high levels of energy and protein. Quality and energy significantly reduced after heading. Manage potential for prussic acid and nitrate build-up.

Planting Date: Late May – early July (soil at 62°F+)

Seeding: Drill 20-30 lbs/acre ½-¾” deep or Broadcast 25-35 lbs/acre. (Higher seeding rates result in finer stems for improved hay drydown.)
