Effect of Different Types of Biochar on Growth of Cocoa Seedlings (Theobroma cacao L.)
Background and Objective: Biochar as a soil amendment is used to improve soil fertility
and ultimately enhances the plant growth. This study aims to determine the effect of
different types of biochar on soil nutrients and plant growth of cocoa seedlings. Materials
and Methods: The study was carried out in the glasshouse of Agricultural Faculty, Halu Oleo University, Kendari, Southeast Sulawesi from June to September, 2018. The study was conducted besed on a randomized block design with 4 replications. Biochar treatment consisted of cocoa pod husk biochar, durian shell biochar, rice straw biochar and without biochar. The variables observed were plant height, leaf area, number of leaves, shoot dry weight and soil fertility. Results: The results showed that types of biochar significantly improved growth of cocoa seedling. Cocoa pod husk biochar showed better effect in improving soil nutrient and growth of cocoa seedlings as compared to the durian shell biochar and rice straw biochar. Conclusion: Cocoa pod husk biochar can be recommended for improving the cocoa production and soil-C sequestration in the study region.
