Sorghum is one of the Cereal crops that can adapt to a broad and prospective development on marginal land, especially on dry land. The average productivity of sorghum stems ranged between 30-50 tonnes / ha and leaves 20-40 tonnes / ha. Potential biomass sorghum can also be improved further by optimizing the potential of sorghum ratoon. The specialty of the sorghum crop is the ability to grow back after being cut or harvested called ratun. Ratoon sorghum can be done 2-3 times, so it can meet the needs of sorghum biomass raw materials or sustainable seed. Planting ratoon not involve the planting of seeds for regeneration using stem, and is a useful tool to start cultivation in drought conditions. Cultivation of sorghum with ratoon system has been applied by farmers in dry areas. Not only in Indonesia but also in India, Africa, and even the United States.
