Viking 304 BMR Brand Sorghum-Sudangrass

Untreated Seed
  • Photo-period sensitive (PPS); BMR (Gene 6)
  • Long photoperiod prevents heading out until late Sept. in northern U.S.
  • Grows a bit slower at beginning of the season than non-PPS hybrids but increases growth rate later; about 6.5’ high at end of season
  • Shorter internodes than standard photoperiods; very leafy with a high leafto-stem ratio
  • Stands better than many other PPS hybrids
  • Typically used of haylage or silage, but can be grazed; PPS allows for a longer grazing period before plants head out, or later, single-cut silage harvest
  • Retains nutritional quality for a wide window of harvest
  • Can postpone silage harvest up to 50”- 80”; wilt before ensiling or frost (65% moisture is best harvest moisture)
  • Plant will gain height at the end of the season for mechanical harvest
  • Good sugarcane aphid tolerance

A hybrid cross between forage sorghum and sudangrass; intermediate in size and yield. Fast-growing, highly productive, multi-cut, warm-season annual grass bred to maximize summer forage. Most hybrids can grow 8′ tall if left uncut. Protein can reach 14% but has less energy than corn silage, because it lacks grain.

Best Use: Best suited for grazing, green chop, baleage, or silage.

Adaptation: Good soils, but is drought tolerant. Likes hot weather. All hybrids we sell are resistant to downy mildew and anthracnose.


  • Usually harvested 45-55 days after seeding or when 40 inches tall, whichever comes first.
  • Cut 6” above ground for best regrowth. Larger stems make drying for hay more difficult than with sudangrass.
  • High planting rates produce finer stems which dry better with increased quality.
  • Manage risk for prussic acid and nitrate concentrations during drought or following frost.
  • Protein will decline as harvest is delayed. If planning to cut only once, energy will increase upon heading due to continued sugar formation in the sorghum stalks and leaves, and carbohydrate deposition in the developing grains.

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

Seeding: 20-40 lbs/acre drilled, 25- 45 lbs/acre broadcast. Use high end of the rate for finer stems and faster drydown. Plant ¾”-1½” deep.
