It is commonly used as a versatile forage option for grazing, hay, or silage. While straight sorghum has the highest potential for poisoning, and straight sudangrass, the least, sorghum-sudangrass has the potential to lean either way. At this point in the season dry hay and silage will be the safer option. Safened seed is required if using Dual or Bicep-like herbicides containing s-metolachlor. Under less frequent cutting, they are more vigorous. 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). Organic, Organic Annuals, Sorghum Sudan. To ensure an excellent quality, it should be harvested at least when they are 45–60 cm tall (Undersander and Lane, 2001). They are higher yielders than sudangrass, with better regrowth for grazing or multiple harvests. Chopping increases nematicidal potential. Sweet six has a dry stalk trait which improves dry down time after cuttings. Use a flail mower in August when it's time to incorporate the sudangrass. This makes them a prime candidate for dual purpose use as both cover crop and forage. We have direct-chopped sorghum, sorghum sudan, sudangrass and pearl millet. Lowering chopping lengths can further increase methane yield up to 13% . 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. Prussic acid (hydrogen cyanide) poisoning can occur when the sorghum species (forage sorghum, sorghum-sudangrass, sudangrass, and Johnsongrass) are frosted. 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. Multiple harvest management for sorghum-sudangrass or sudangrass increases forage quality for lactating cows but can reduce yields by as much as 50% compared to a single harvest. Sorghum sudan and pearl millet must be wilted before chopping if ensiled to avoid poor fermentation. Manure can be used as a nitrogen source but is not recommended. Sorghum and sudangrass crops, under normal conditions should be 18 inches tall before grazing or green chopping to prevent prussic acid toxicity. Weeds. Will survive light frost.
