The majority of Tuban Regency is predominantly low fertility alfisol soil with low P nutrient availability for plants. Therefore, it requires BPF to convert insoluble phosphate into available P, supported by the application of FMA to maximize nutrient uptake through the hyphae formed on chili plant roots. This study aims to determine the growth response of cayenne pepper when applied with BPF and FMA planted in alfisol soil. The research used a randomized block design (RBD) with 8 treatments replicated 3 times, resulting in a total of 24 experimental plots. The treatments include Control; P Fertilizer; BPF; FMA; P Fertilizer + BPF; P Fertilizer + FMA; BPF + FMA; and P Fertilizer + BPF + FMA. The observed plant growth parameters include flowering time, growth vigor, plant height, leaf count, and stem diameter measured at the onset of flowering and early harvest. The results showed that the application of BPF and FMA, individually or in combination, was able to enhance the growth of cayenne pepper plants. The best treatment in this study was P Fertilizer + BPF + FMA with the respective average parameters such as flowering time of 48.333 days after planting (DAP), growth vigor of 1.000, plant height at the onset of flowering of 51.750 cm and at early harvest 60.500 cm, leaf count at the onset of flowering of 57.333 leaves and at early harvest 115.333 leaves, and stem diameter at the onset of flowering of 8.1833 cm and 12.3000 cm at early harvest.
