MS 9000 displays rapid growth and can reach heights of 6-8’ tall at maturity. KF Sugar Pro 55 Organic $ 2.28 per lb Total (50 lbs): $ 114.00. Prussic acid (hydrogen cyanide) poisoning can occur when the sorghum species (forage sorghum, sorghum-sudangrass, sudangrass, and Johnsongrass) are frosted. Frost/freeze events are obvious condition that can lead to plant cell rupture, in addition cutting, chopping, chewing, drought, and maturity are additional sources. Use a flail mower in August when it's time to incorporate the sudangrass. These tall, fast-growing, heat-loving summer annual grasses can smother … sudanense) has high palatability and does not produce toxic compounds that threaten livestock and horses (Mojtahedi et al. SP4105 can expand the window for usage because it will not head under most conditions. They also have a long history as livestock feed harvested as hay, haylage or pasture. Annual grass. Sorghum and sudangrass crops should be 18 inches tall before grazing or green chopping to prevent prussic acid toxicity. Sorghum-sudangrass hybrids have higher stalks than sudangrass and are normally harvested for green chop or silage but may be used for pasture or hay if chilled at a high seeding rate and harvested at immature stages (18 to 24 in. Chopping increases nematicidal potential. Watch your forward speed. Sorghum and sudangrass crops should be 18 inches tall before grazing or green chopping to prevent prussic acid toxicity. Use sorghum-sudangrass to help control nutsedge infestations, suggests Cornell Extension IPM vegetable specialist John Mishanec. One hundred pounds of nitrogen is recommended at planting and a second application of 100 pounds of nitrogen following first cutting is recommended for high yield potential. Sorghum × sudangrass are not suitable for hay because of the thickness of their stems, which are difficult to cure or to crush and crimp. Again, weather conditions will influence the success of this practice. As long as the hay is cured correctly it is rare for it to contain toxic levels of prussic acid. Sorghum-sudangrass hybrids are also significant users of nitrogen. Forage sorghum, sudangrass, and sorghum-sudangrass hybrids (sudex) are exceptionally heat and drought tolerant annual crops that are used as cover crops, pasture, hay, and silage. There is normally more seepage because of the higher moisture content at harvest. Sorghum-sudangrass: For the best quality and yield under a multi-cut program, harvest at 40 days or 40 inches of growth, whichever comes first. The danger of poisoning is highest in the early growth stages and following a light frost. Under less frequent cutting, they are more vigorous. Sorghum Sudangrass is a warm-season annual grass developed as a hybrid cross between forage sorghum and sudangrass. Sorghum, sudangrass, sorghum sudangrass and millet typically have lower forage quality than common Wisconsin forages. Green chop - Sudangrass and sorghum-sudangrass hybrids can be used to provide green chopped forage over summer. While straight sorghum has the highest potential for poisoning, and straight sudangrass, the least, sorghum-sudangrass has the potential to lean either way. Photo: T. Baugher, Penn State. BMR Sorghum/Sudangrass - Organic Sorghum x drummondii. Ensiling Forage Sorghum and other Summer Annuals Forage sorghum is typically wetter at harvest than corn, but will ferment well. Buy yours here! 1993).Some varieties, most notably Trudan 8, also have nematicidal properties. Sorghum sudan and pearl millet must be wilted before chopping if ensiled to avoid poor fermentation. You will quickly pass the cutting speed of the head, which will leave longer stubble in the field and a potential yield loss. We have direct-chopped sorghum, sorghum sudan, sudangrass and pearl millet. 3.8. Flail-chopping sorghum-Sudangrass Chopped residue ready for incorporation Prussic acid poisoning is a concern if you plan on feeding these crops to livestock. Sorghum-sudangrass should be 24 to 30 inches tall before grazing. Immediately incorporate the sorghum-sudangrass. A vigorous, competitive and adaptable hybrid annual that likes heat and high fertility. Do not graze wilted plants or plants with young tillers. Sorghum-sudangrass hybrids with the brown midrib (BMR) gene will produce forage with higher fiber digestibility, making it more like corn silage. At the latest, harvest when 50 percent of the plants have reached the flag leaf stage. Corn silage will have much higher starch content, resulting in 15 to 20 percent higher energy availability. Chopping increases nematicidal potential. Will survive light frost. The cultivation of catch crops after early harvested crops represents a good possibility for the cultivation of energy crops, but presupposes a harvesting yield in only a few months of vegetation (<4 months). Yields have ranged from 3 to 5 tons/A dry matter. Great for dairy, heifer, dry cows. Harvesting at this height will promote more rapid re-growth. Safened seed is required if using Dual or Bicep-like herbicides containing s-metolachlor. It is commonly used as a versatile forage option for grazing, hay, or silage. Sudangrass. Another warm season grass to consider is planting corn silage after small grain harvest. Sorghum and sudangrass crops, under normal conditions should be 18 inches tall before grazing or green chopping to prevent prussic acid toxicity. All sorghums should be safe when harvested as dry hay. This makes them a prime candidate for dual purpose use as both cover crop and forage. Mow sudangrass about a month after planting, when stalks are 3 to 4 feet tall. Grows best in warm weather when other grasses slow down. Read more. Base this second application on moisture levels and yield potential. Seed at 40–80#/acre, 2#/1000 sq ft when soil is thoroughly … The harvest head needs to be down on the ground to get as much of the crop as possible, as it is all highly digestible forage. Dual purpose cover crops can help … Flail chopping after frost or killing the cover crop with herbicide will create a suitable mulch for no-till planting, preserving soil life and soil structure in non-compacted fields. BMR 6 dry stalk sorghum sudan. Sorghum-sudangrass hybrids have coarser stems and broader leaves than true sudangrass. Forage sorghum silage with the BMR-6 trait has similar nutritive value to corn silage ... it is recommended to monitor moisture in the swath and schedule chopping and hauling accordingly for desired dry matter. Sudangrass, forage sorghum, and sorghum-sudan hybrids will tolerate moderate levels of atrazine. Pest Management Weeds. As long as the hay is cured correctly it is rare for it to contain toxic levels of prussic acid. Grass, Sorghum Sudan. In central Wisconsin, yields have been around 3 to 5 tons of dry matter (DM) per acre. Use sorghum-sudangrass to help control nutsedge infestations,suggests Cornell Extension IPM vegetable specialist John Mishanec. Begin chopping after the plant is 18 inches tall or cut at least 10 days after a killing frost to avoid prussic acid concerns. At this point in the season dry hay and silage will be the safer option.
