Abstract

Various constraints are still faced by purple eggplant farmers, including poor soil fertility conditions and the suboptimal use of organic materials, which lead to low production yields. Therefore, this study was conducted to analyze the effect of applying biochar derived from rice husk charcoal and vermicompost on the growth and yield of purple eggplant plants. This study was arranged using a Randomized Block Design (RBD) with two treatment factors. The first factor was the application of rice husk biochar consisting of four levels: B0 (topsoil as control), B1 (rice husk charcoal : topsoil = 1:1), B2 (rice husk charcoal : topsoil = 1:2), and B3 (rice husk charcoal : topsoil = 1:3). The second factor was the application of vermicompost, also consisting of four levels: V0 (0 g/polybag as control), V1 (75 g/polybag), V2 (150 g/polybag), and V3 (225 g/polybag). The observed parameters included plant height, stem diameter, number of fruits per plant, number of fruits per sample, fruit weight per plant, and fruit weight per sample. The results showed that the best treatment for vegetative growth was obtained at B1 (rice husk charcoal : topsoil = 1:1), while the best treatment for increasing production was obtained at B3 (rice husk charcoal : topsoil = 1:3). The application of vermicompost had a significant effect on plant height and stem diameter, with the best treatment found at V3 (225 g/polybag).
