• Best summer annual option when dry hay production is planned
  • Strong emergence & quick regrowth
  • Rapid growth & regrowth (faster than sorghum x sudangrass)
  • Lower prussic acid risk than sorghums
  • Tolerates poor fertility and low pH


  • Grazing – Recommended beginning height is 18 to 24 inches with a stop height of 6-8 inches (or at least 2 nodes remaining)
  • Hay/Baleage – more suitable than sorghum x sudangrass for dry hay – optimal timing is 40 days or 40 inches
  • Dense stands offer multiple cover crop advantages – from weed suppression to nematode control
  • Emergency hay or pasture option

  • Average seeds/pound: 35,000–40,000

  • Please test your soil!

Avoiding Nitrate and Prussic Acid Poisoning:

  • Do not harvest drought stricken plants within four days following a heavy rain
  • Do not apply nitrogen prior to expected drought periods
  • If in doubt, cut at higher stubble height as nitrates tend to accumulate in the lower stalk
  • If high prussic acid is found, wait one month prior to feeding. Unlike excessive nitrates, prussic acid will escape from the plant over time


  • First cutting: for best quality, plan to harvest within 40 days of growth and less than 40 in. of growth
  • Cutting height: for optimum regrowth, crop should be harvested
    leaving two nodes or approximately 6-8 in. of plant material
  • Use sharp blades: a clean cutting will enhance regrowth
