With its drought tolerance and high yields Sorghum is a very interesting crop for forage and biogas in warm & dry areas.
Sorghum prefers warm areas. Drought doesn´t damage sorghum so much. The drought tolerance is better than maize. After a drought period it begins to regrow and make new green stems and leaves. The youth develop is very slow, especially if the spring has cold temperatures.
Sorghum doesn´t have many claims to the soil. Dry areas or areas with a low soil quality are sufficient. Only cold and humid areas aren´t suitable.
Tillage The tillage technique is same like maize.
Sowing Sowing time: Sorghum doesn´t like cold temperatures. A warm germination temperature is necessary. Seeding date should be in the mid of May and when the soil temperature is > 12 °C.
Amount of seeds: 10-12 kg/ha. Sowing depth 2-4 cm, row distance: 25-50 cm, that are approximately 35-45 grains/m².
