Product Description

KingFisher Summer Prince is a blend of photo-period sensitive sorghum-sudans. Summer Prince features premium varieties that are all photo-sensitive for an extended harvest window and consistent quality throughout the growing season. Its best to plant when receiving 12 hours of daylight each day. 

Description

Sorghum-sudangrass crosses are a warm-season, or C4, grass. Because warm-season grasses process sunlight into sugars (photosynthesis) differently than do coo-season (C3) grasses. Sorghum-Sudangrass:

  • Must be planted after soil temperatures reach 60 degrees F and are rising
  • Grow very little at temperatures lower than 60 degrees F
  • Grow best at 77 degrees F
  • 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. There 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. 

Management

Sorghum-sudangrass will be harvested for baleage or haylage about 45 days after planting. Grazing is usually initiated a week to 10 days earlier. 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 3- -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.

Establishment

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.
