This study aims to understand the effectiveness of biofertilizers and shoot pruning in improving cocoa growth and yield. The research was conducted in the “Kebun Dinas Bone-Bone”, North Luwu Regency, South Sulawesi Province from February to August 2020. This research was conducted in the form of an experiment arranged in randomized block design (RBD) with 3 replications. The treatment consist of 10 levels, namely: without biofertilizer and not shoots pruned, biofertilizer 9 ml L−1 per tree and not shoots pruned, biofertilizer 18 ml L−1 per tree and not shoots pruned, biofertilizer 27 ml L−1 per tree and not shoots pruned, biofertilizer 36 ml L−1 per tree and not shoots pruned, biofertilizer 0 ml L−1 per tree and shoots pruned, biofertilizer 9 ml L−1 per tree and shoots pruned, biofertilizer 18 ml L−1 per tree and shoots pruned, biofertilizer 27 ml L−1 per tree and shoots pruned, biofertilizer 36 ml L−1 per tree and shoots pruned. Research results show that the concentration of biofertilizer of 32 mL L−1 gave the highest value for number of pods (10 pods), 42.8 seeds of fruits, and yield 0.71 kg per tree or equivalent to 591.67 kg/ha of dry seeds. Pruning the shoots gave the highest number of seeds per fruit of 36.82 and pod index of 20.
