Greengrazer V Sorghum Sudangrass

  • Small-seeded and thin-stemmed type
  • Dark green color with Green Top trait
  • Anthracnose and Downy Mildew resistant

Greengrazer V is a small-seeded three way cross with thin stems that are highly palatable. Regrowth after cutting is very fast. Greengrazer V is a dark green color and also possesses the Green Top trait, which allows for further extension of the plant. Planting Greengrazer V at higher populations per acre will result in a finer stemmed forage. Finer stems will allow the forage to dry faster for higher quality hay than is possible with thick stemmed types. For grazing, wait until plants are 18”-36” tall. Remove cattle when plant height has been grazed down to 8”.

Rate (Lbs.)DrylandIrrigated
Seeds/Sq. Ft.:5-1417-48


Adaptation Ratings:
Photosynthetic Type:C4 – Warm Season
Soil Temperature:Warm (60 F)
Water Requirement:Very Low


  • Soil temperature should be at least 60 F.
  • Greengrazer V is usually planted between June 10 and July 10 in the northern states.
  • Can be no-tilled into the stubble of winter and spring crops.
  • Planting depth should be 1”.
  • Do not plant in soils with pH greater than 7.5 to 8.0. Chlorosis will be a severe problem.


  • Greengrazer V is usually harvested 63-65 days after seeding.
  • Protein will decline as harvest is delayed, but energy will increase upon heading due to continued sugar formation in the sorghum stalks and leaves, and carbohydrate deposition in the developing grains.

Avoid Nitrate and Prussic Acid Poisoning from sorghum:

Avoid large nitrogen applications prior to expected drought periods. 2,4-D can increase Prussic Acid concentration for several weeks after application. Do not harvest drought-damaged plants within 4 days following a good rain. Do not green chop within 7 days of a killing frost. Cut at a higher stubble height, nitrates tend to accumulate in the lower stalk. Wait 1 month before feeding silage to give Prussic Acid enough time to escape.
