The optimization of planting media enriched with biochar & Black Soldier Fly Larvae (BSFL) frass

In Malaysia, the organic food business is confronting many issues. The demand for organic food is increasing but the supply of organic food in the area is not keeping up. As a result, Malaysia continues to rely largely on imported organic food. Over fertilisation or lack of fertiliser are also one of the challenges that is faced by our organic farmer. In order to solve all these problems, planting media enriched with biochar and BSFL would be the best solution. The aim of this study was to identify the effects of different ratios of planting media enriched with biochar and Black soldier fly larvae (BSFL) frass on jimao choy. The growth parameters, pH and yield of the plants were observed in this research. There are seven treatments with three replications for each. Biochar and BSFL frass are used as treatment with different ratio. This study was used a completely randomized design (CRD) experimental design method. Besides, the NPK content in the biochar and frass also have been identified. In addition, ANOVA and Tukey’s Honest Significant Difference test are used to test the hypotheses of this research. From the results obtained, it shows that planting media enriched with biochar and BSFL with the ratio 0 : 1 (T1) and 2 : 1 (T6) has a good plant development rate compared to other treatments in many things. Results show that frass has high nutrient content compared to biochar. This study employs organic agricultural techniques, which limit the use of chemical compounds such as herbicides, insecticides, and chemical fertilisers.
