What is the seeding rate for BMR?
Seeding rate: 35 lb/acre if drilled, 40 to 50 lb/acre if broadcast. Seeding depth should be 0. Planting rates vary from 20 to 40 pounds per acre depending on whether the seed is broadcast or planted in rows. Planting dates are usually from May to July but can be earlier in the deep South. Soil temperature needs to be a minimum of 60 degrees Fahrenheit for germination. Seeding depth should be 1 inch.For conservation purposes, seeding rates have been established to achieve the desired plant density of around 20-60 live seeds per square foot. These figures are fairly standard when figuring seeding rates except when you are dealing with very large or very small seed sizes (e.PLANTING RATES: Sudangrass should be planted at a rate of 120 to 150 pounds of seed per acre.A seed rate of about 25 kg/ha is required, but this depends on the seed size. Seed rate and planting There are two major ways to plant and space you maize seeds; i) you can plant 2 seeds per stand at 90 x 45 cm to get a population of 48,000 plants per hectare.
What are the disadvantages of sudan grass?
Sudangrass can accumulate nitrates and prussic acid (hydrogen cyanide) in its tissues under certain conditions of stress, such as during a long drought, after a frost, or following overgrazing. Nitrates and prussic acid can poison livestock, causing health issues and possibly death. Sudangrass – grows from 4 to 7 feet tall, has leaves about 1⁄2 inch wide and stems about 1⁄4 inch in diameter. It can be harvested as pasture, green chop, hay, or silage. Yields have ranged from 3 to 5 tons/A dry matter. It can be ready for harvest as early as 45 days after planting.While sudangrass has lower prussic acid potential than sorghum-sudangrass, it’s not risk-free. Avoid grazing until plants are at least 15 inches tall, and never graze immediately after a frost or during drought stress. After frost, wait 7 to 10 days before turning cattle back in.While sorghum-sudangrass has higher yield potential, sudangrass is leafier with much finer stems, which provides higher forage quality. New BMR (brown mid-rib) types of both species are available, which provide low-lignin, higher fibre digestibility (NDFD) for improved forage quality.Sorghum-sudan grass isn’t a common horse feed, but you can feed it during droughts, especially when other forage is limited. If buying sorghum-sudangrass during a drought year, test the forage for cyanide and nitrate content before feeding it. Don’t feed forage positive for cyanide.Sudangrass planted in the late summer with a yield potential of about 12 tons needs between 125 and 150 pounds of actual nitrogen per cutting. If this is to be applied with the irrigation water, most of the nitrogen should be applied so that it is available as the plants are making rapid growth.
How many times can you cut sudan grass?
Sudangrass can be harvested as pasture, hay or silage, but is best used for pasture. Yields of 3 to 4 tons/acre of dry matter. It can be pastured 5 to 6 weeks after planting and may be cut or grazed multiple times (when regrowth reaches 18 to 20 in. With finer stems and leaves than sorghum-sudangrass, Piper Sudangrass can be used for hay or grazing. Piper is known for its rapid growth and lower prussic acid content than sorghum sudangrass. It produces large amounts of organic matter and suppresses weeds.Generally, well-watered and not wilted, sudangrass or sorghum taller than about 20-in should be safe for grazing. However, because many environmental, animal behavior and animal physiological factors influence the risk of intoxication, testing is recommended to protect animal health.Sudangrass – grows from 4 to 7 feet tall, has leaves about 1⁄2 inch wide and stems about 1⁄4 inch in diameter. It can be harvested as pasture, green chop, hay, or silage. Yields have ranged from 3 to 5 tons/A dry matter. It can be ready for harvest as early as 45 days after planting.
What is the seeding rate for sorghum Sudangrass hybrid?
Planting rates vary from 20 to 40 pounds per acre depending on whether the seed is broadcast or planted in rows. Planting dates are usually from May to July but can be earlier in the deep South. Soil temperature needs to be a minimum of 60 degrees Fahrenheit for germination. Seeding depth should be 1 inch. Seeding depth should be 0.In extension studies, seeding rates used are typically between 75,000 and 225,000 seeds per acre.
What is brown midrib sorghum sudangrass?
BMR (Brown Mid-Rib) Sorghum Sudangrass. Winner’s Choice BMR (Brown Mid-Rib) sorghum-sudangrass is a premium forage option known for its exceptional digestibility and high biomass production. This brachytic BMR 6 variety produces forage with a great leaf-to-stem ratio and excellent tonnage. Sorghum sudangrass requires approximately 30 lbs of N, 9 lbs of P₂O₅, 34 lbs of K₂O, and 6 lbs of S per ton of forage produced. Make fertilizer applications based on expected yield and soil fertility levels. Apply ½ rate of nitrogen before or immediately after planting, and the other ½ rate 30 days after emergence.Potential yields range between 680- 1800kg/acre or (8-20 bags /acre. Sorghum grows well in areas with an elevation of 50-1800m above sea level and receiving a minimum of 250mm of rain well distributed per season. It is suitable for cultivation in many parts of the country.Grain moisture content typically varies between 25 to 40% depending on sorghum product selection and growing conditions. Total time from flowering to physiological maturity is approximately 40 to 45 days.The common name is sorghum, Sudangrass, or Sudan grass (Marks and Townsend, 1973).
When to plant sudan grass?
Seeding date June through mid-August (sudangrass). July through mid-August (sorghum-sudangrass). These cover crops require warm soil to germinate. The potential for greater tillering with earlier planting dates makes sorghum yields more stable when planted in May and early June than in late June or July.
