Biocharcoal and Boron Application for Increased Sweet Sorghum Production for Food, Feed, and Energy

Source: SEAMEO BIOTROP's Research Grant | 2011


Sorghum is the fourth in the list of priority crops of Indonesia. The growing interest on sorghum cultivation in Indonesia and elsewhere in the world is because of its multi uses and ability to survive in dry and marginalized areas and climate changes.

The Centre came up with the proper formulation and methods of applying boron and biocharcoal to increase the production of sweet sorghum. With boron application of 1 kg/ha, the average sorghum grain weight (per 1,000 seeds) increased by 36% and the grain yield increased by 24% per ha. Setting the optimum concentration of biocharcoal at 7.5% per ha enhances sorghum’s nutrient intake from the soil and also increases its sugar content. Further, the effects of boron and biocharcoal application can extend the harvesting time of sorghum up to 85-90 days after planting while at the same still producing good quantity and quality of seeds and juicy stems and leaves for ethanol and forage productions.
