Abstract

This study aims to determine the effect of applying rice husk biochar and consortium biofertilizers to improve the physiological processes of cocoa (Theobroma cacao L.) plants. This research was conducted at the Mars Cocoa Research Station Gardens in Pangkep Regency using an experimental method with the design used, namely the Two Factor Factorial (F2F) arranged in a Randomized Block Design (RBD). Four levels of rice husk biochar were used as the first factor consisting of (r0), 5kg/tree (r1), 10kg/tree (r2), and 15kg/tree (r3). The second treatment factor was the consortium biofertilizer (m) consisting of 4 levels, including without consortium biofertilizers (c0), 20 ml/L (c1), 40 ml/L (c2), and 60 ml/L (c3). Data analysis was carried out by collecting data and processing it in the form of variance (ANOVA) and then proceeding with the Tukey test with a level of alpha 0.05. The results showed that the application of rice husk biochar and consortium biofertilizers had a significant effect on the parameter Leaf Mass per Area (0,049 g.cm-2), chlorophyll a (271,83 mmol/m2), chlorophyll b (111,73 mmol/m2), and total chlorophyll (389,83 mmol/m2). However, the treatment did not significantly affect the application of rice husk biochar and the consortium's biofertilizers was the stomatal density parameter (264,12 mm2).
