Product Description


AS6402 is a Brachytic Dwarf- Internodal distance (space between leaves) is much shorter. AS6402 yields are equal or greater than AS6501 or AS6401 with more of the tonnage being leaves rather than stalk. This also makes it easier to graze. 

  • This brachytic dwarf can be mowed to 4″ residual and still maintain rapid regrowth
  • Expect high yields with tonnage being leaves rather than stalk
  • BMR Gene 6
  • Disease Tolerance is very good

Must be planted after soil temperatures reach 60 degrees F and are rising. Will produce a ton of silage with half the rain or irrigation needed by corn silage After germination, sorghum-sudangrasses thrive in hot, dry weather. They die soon after a freeze. These forages produce quick tons of highly digestible (high-energy) silage or pasture; they are an excellent source of pasture for the hottest months.

BMR (brown mid-rib) is a natural trait (not GMO) that produces lower levels of lignin in these plants. BMR Gene 6 is the highest BMR level, meaning that it contains the lowest level of lignin of any sorghum or sudan. This trait transforms sorghum products from heifer feed to the highest_quality dairy cow feed. AS6402 is a brachytic dwarf, a natural (not GMO) trait that provides these plants with at least four advantages:

  • Shorter residual cutting height
  • Shorter space between leaves (internodal distance)
  • Shorter stalk but with more leaves, a quality improvement
  • Higher tillering capacity


Sorghum-sudangrass will be harvested for baleage or haylage about 45 days after planting. Grazing is usually initiated a wee to 10 days earlier. Brachytic dwarf, can be mowed with a 4-inch residue, which is one reason for its popularity. Caution: Regrowth can be almost zero if the residual is too short.

Fertilizer needs are 1 to 1 1/4 units of nitrogen per growing day, i.e., 45 to 50 units for the first cut and 30 to 35 units for each subsequent cut. Potassium, phosphorous and sulfur are also needed on most farms. All fertilizer needs are the equivalent of the needs for 100-bushel corn.

Manure can be used for the original application of fertilizer; however, commercial nitrogen is the best source after a cutting. Nitrogen needs for grazed sorghum-sudangrass must be reduced proportionally so that cows can be brought in to graze earlier without danger of nitrate poisoning. Sorghum-sudangrass should not be grazed for 7-10 days after a killing frost as it takes about seven days for the prussic acid produced by the frost to dissipate. 


Sorghum-sudangrass usually emerges in about 10 days and then can grow 3 to 6 inches per day. A conventional or no-till drill is used for the seeding, and planting depth should be 1 to 1 1/2 inches. 

Planting after a small grain crop (rye or triticale, for example) requires dealing with the allelopathic effects from the dying grain plants. This can be accomplished with either minimum tillage or heavy application of liquid manure. Because no herbicides are available for sorghum-sudangrass, weed-management activities must precede planting.
