The new Sudangrass hybrids are very aggressive, drought tolerant summer annuals. They emerge quicker and have faster regrowth than sorghum sudan (SS). Finer stems can give superior quality with the same tonnage as SS.
Sudangrass is easy to establish but does require 60°F soil temperatures (and rising). It can be grazed or cut for baleage or haylage with an optimum harvest height at 40". Sudangrass can be made for dry hay in the southern zones but it MUST be cut by 30" to achieve dry down. It responds well to applied fertility or manure. Timely cutting (45 days after planting and 30 days for subsequent cuts) is important as quality will decline as it reaches maturity.
Seeding rates are 25-35 lb/acre. Seeding depth is 3/4" to 1" deep. It is best to get the seed into the moisture. If inter-seeding into existing hay or pasture stand, make sure the grass is cut short to achieve good establishment.
