Cover Story: Our study found that rice husk biochar addition on upland field converted paddy could greatly improve growth and yield of sesame as well as seed mineral contents. The study showed that the higher rate of biochar addition significantly improved the seed yield of sesame in the first cropping whereas in the second cropping field, biochar addition did not significantly influence seed yield. The overall improvement in the sesame growth, seed yield and mineral contents especially K was attributed to mainly increased K availability, soil pH, CEC, improved porosity and bulk density. Our study also highlighted that rice husk biochar addition may not have a long lasting effect on sesame yield on upland field converted paddy since the positive effect of biochar tended to fade in the second cropping suggesting one time application would not be sufficient.
