Byron’s 577 DS sorghum-sudan has BMR 6 gene technology. BMR gene improves feed intake and digestibility of silage or hay. Byron’s 577 DS is a photo-period sensitive sorghum-sudan. Photoperiod gene ensures delayed maturity and a vegetative stage of growth across varying environments providing a multi-leaf hybrid with up to 20 leaves per plant.
- Drought tolerant
- BMR 6 Gene reduces plant lignin content by 40-50% versus conventional photoperiod sensitive hybrids
- High Sugar Content at 150 days
- Energy from forage versus grain
- A white seed, Seeds/lb. 14,500 approx.
- Maturity- 160-180 days
- Height 10-12 feet
Sorghum- sudan must be planted after soil temperatures reach 60 degrees F and are rising. Byron’s 577 DS must be receiving a minimum of 12 hours and 20 minutes of daylight prior to planting. 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 planted. Grazing is usually initiated a week to 10 days earlier. Non-brachytic versions must be mowed with at least 6 inches of residue (above the second growth node) to promote rapid regrowth. Caution: Regrowth can be almost zero if the residual is too short.
Fertilizer needs are 1-1 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 take 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 3to 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.
