KingFisher Summer Dream is a blend of three BMR 6 brachytic dwarf sorghum-sudans. Summer Dream brings the best of brachytic dwarfs in a strategic blend for high yield, excellent quality, and fast regrowth. Most fields have a variety of high and low spots as well as soil types. Each variety in a blend performs best in different areas. Thus raising the yields of the poor spots in a field.
Sorghum-sudangrass crosses are a warm-season, or C4, grass. Because warm-season grasses process sunlight into sugars (photosynthesis) differently than do coos-season (C3) grasses. Sorghum-Sudans:
- 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 and higher
- 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.
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 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.
