Product Description

AS6501 hybrid sorghum sudangrass is a premium product with the photoperiod sensitive (PPS) characteristic which provides a wide window of harvest and consistent quality over the entire growing season. This product also features the BMR 6 gene for increased utilization and efficiency. The photoperiod sensitive characteristic means AS6501 has a wide window of harvest. AS6501 will remain in the vegetative state when the plant receives a minimum of 12 hours and 20 minutes of daily sunlight allowing for the greatest harvest flexibility. Once day length falls below this threshold, it goes to a reproductive state.

  • Photoperiod sensitive
  • Extended harvest window
  • Excellent re-growth after harvest
  • Exceptional drought tolerance
  • BMR-6 provides high-quality nutrition

Establishment

Soil temperature should be at least 60º F. Avg. Seeds per Pound: 13,000 – 15,000. Planting depth should be 1”. Can be no-tilled into the stubble of winter and spring crops. Do not plant in soils with pH greater 7.5 – 8.0 as Iron Chlorosis can be a severe problem.

Management

A soil test is highly recommended to establish a base line of fertility requirements. Under favorable growing conditions, apply 1 to 1.25 lbs. of nitrogen per day of planned growth. For example, for a planned 60-day harvest, apply 50 to 75 lbs. of nitrogen; for a subsequent planned 30-day cutting, reapply 30 to 37 lbs. of nitrogen. Reduce nitrogen rates for less than optimum growing conditions. Potassium levels should be kept up, particularly if the soil pH is lower than 6.2. If soil pH is above 7.0, a foliar application of iron may be necessary or Iron Chlorosis (yellowing of the leaves) may be a problem. This can be reduced by foliar feeding iron while plants are still young. Avoid large nitrogen applications prior to expected drought periods which can increase Prussic Acid concentration for several weeks after application.

Harvest

For the best quality and yield under a multi-cut program, harvest at 40 days or 40 inches of growth, which ever comes first. Sorghum species dry slowly because of their drought tolerance. One method of managing drydown in silage is to swath the crop, allow it to wilt to a desired moisture level, and then pick up the wind rows with a silage chopper. Protein will decline as harvest is delayed. Energy will increase upon heading due to continued sugar formation in the sorghum stalks and leaves, and carbohydrate deposition in the developing grain. Careful attention should be paid to the cutting height. For regrowth, 2 nodes or 6 inches of stubble is optimal. Sharp blades provide for a clean cut and enhance regrowth.

Do not harvest drought-damaged plants within four days following a good rain. Do not greenchop within seven days of a killing frost. Cut at a higher stubble height, nitrates tend to accumulate in the lower stalk. Wait one month before feeding silage to give Prussic Acid enough time to escape.

Sorghum Sudan

Sorghum Sudan crosses are a warm season or C4 grass. These warm season annuals can produce lots of forage in a short period of time during the summer months.  Most grazing farms should have a percentage of their farm in sorghum sudangrass to help fill in the summer slump when the cool season pasture is slowing down. Warm season grasses process sunlight into sugars (photosynthesis) differently than do cool-season (C3) grasses. Heat, moisture and fertility will make Sorghum Sudan very productive. The rami-fications are that C4 grasses 

  1. must be planted after soil temperatures reach 60°F and are rising, 
  2. grow very little at less than 60°F, 
  3. grow best at 77°F and higher and 
  4. will produce a ton of silage at 1/2 the rain or irrigation than will corn silage.

Hot and dry is their ideal environment after germination. C4 grasses 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. Other C4 grasses include all Sorghum and Sudans, plus Millet, Teff, Bermuda and Bahia grasses. When moisture is short they will wait for the rain.
