Enhancing Plant Growth Media by Incorporating Chemically Treated Sago Bark Biochar as Soil Amender

Sago bark biochar (SBB) was produced through carbonization which involves the heating of sago bark waste in the furnace with a limited amount of oxygen. Biochar application as soil amender can alter soil physical properties with its effects on soil aeration, water holding capacity, soil workability...

Results showed that Capsicum annuum L. var. Kulai grown with 1.5 and 3% SBB has the highest number of leaves (122.90 and 118.00, respectively). Plants in 1.5% TSB showed a significantly higher number of fruits(p<0.05) and plant height during four months of the vegetative period. In general, TSB shows better physicochemical characterization and its application in soil has significantly increased the yield of the plant.
