SHORT SUMMARY
 
The Sudan grass (Sorghum × drummondii , often under the synonym sorghum sudanense ) is a plant of the family Gramineae ( Poaceae ) . The Sudan grass is an annual plant, its stalks are between 1 and 2.5 meters tall and have a diameter of 3 to 6 mm . The species is native to northeast Africa in Sudan and Egypt. It can be found there along river banks and irrigation canals , it spreads like a weed .

Sudan grass is a C4 plant , warmth, and quite tolerant of drought. At low soil requirements, Sudan grass prefers warm temperatures and frost- sensitive but considerably drought tolerant than maize ( the dominant Central European arable crop for feed and biogas ) . Sudan grass can interrupt the growth in dry conditions and resume it later . Because of their slow early growth of Sudan grass crops are in the establishment phase as susceptible to weed infestation .

Some cultivars are available. Sowing takes place in May. Harvesting Sudan grass with the forage harvester at the beginning of panicle emergence in the second half of June and again in late October or early November . In field trials were at two harvests between 30 to 44 quintals per hectare ( t / ha ) dt at low income levels and 67-82 / ha are harvested at a high level of income.

Several years of trials in Germany (since 2005 in parallel in seven states ) confirm the basic suitability of plants for cultivation in Central Europe.

Sudan grass is mainly used as fodder plants, while the feed value is slightly lower than that of Silomaises . Because of their Massenwüchsigkeit the plant is also increasing interest in the biogas sector . With pure fermentation of Sudan grass biogas yields of 500 to 600 cubic meters per ton of dry organic substance can be achieved with methane contents of 50 to 55 percent by volume.
