Abstract: Background and Objective: Most of the previous research on biochar amendment to soil reported improvement in soil bio-physical properties. Durian shell availability and its management is a key issue in Asian region, therefore, its conversion to biochar can be viewed as a potential strategy. The application of durian shell biochar (DSB) may improve nutrient availability and water holding capacity for supporting growth and yield of crop. Materials and Methods: The experiments were conducted to improve soil fertility, plant growth and yield of field grown chilli, by applying different amount of durian shell biochar. The experiment was conducted in the dry lands of Kambu Subdistrict, Kambu, Kendari, Southeast Sulawesi on a randomized block design with 5 replications from May, 2018 until August, 2018. Biochar treatment consisted of 3 doses of durian shell biochar: no durian shell biochar (control), 0.5 kg m–2 durian shell biochar and 1 kg m–2 durian shell biochar. Soil moisture, soil hardness, plant height, shoot dry weight, number of fruits and fruit weight were measuring during the study. Results: The results showed that durian shell biochar increased soil nutrient content and decreased soil hardness. Durian shell biochar significantly affected plant height, shoot dry weight, number of fruits and fruits weight. However, dose of biochar application did not showed significant effect on growth and yield. Conclusion: The findings suggest that the conversion of durian shell biomass to biochar and its application to agricultural field can be a better approach for managing this waste in the Asian region.
