The aims of this study were: (1) to determine the effect of NPK Mutiara fertilizer and Kayabio biofertilizer and their interactions on the growth and yield of chilli plants and (2) to obtain the appropriate dose of NPK Mutiara fertilizer and Kayabio biofertilizer for growth and yield of chilli, Dewata 43 F1 variety. The research was carried out from March to May 2020, the research site was on Jl. Toyyib Hadi Wijaya SPP/SPMA Complex, East Sempaja urban Village, North Samarinda sub District, East Kalimantan Province. The study used a Completely Randomized Design (CRD) with 4x4 factorial analysis which was repeated 3 times. The first factor was the dose of NPK Mutiata fertilizer (M) which consisted of 4 levels, namely: no NPK Mutiara application (m0), 5 g polybag-1 (m1); 10 g polybag-1 (m2), and 15 g polybag-1 (m3). The second factor is Kayabio biofertilizers (K), which consists of 4 levels, namely: no Kayabio Hayati Fertilizer application (k0), 15 g polybag-1 (k1), 30 g polybag-1 (k2), and 45 g polybag-1 (k3). Research activities include: preparation of planting media, seed sowing, planting, fertilizing NPK Mutiara, fertilizing Kayabio, plant maintenance (installation of stakes, watering, weeding, pest and disease control), and harvesting and data collection. Data analysis used variance and BNT test at 5% level. The results showed that: (1) NPK Mutiara fertilizer had a significant to very significant effect on plant height at 15, 30 and 45 days after planting, age at flowering, age at harvest, number of fruits and fruit weight per plant. The highest fruit production was produced in the treatment of 10 g polybag-1 (m2), namely 21.33 g; (2) Kayabio biofertilizer had a very significant effect on plant height at 15, 30 and 45 days after planting, age at flowering, age at harvest, number of fruits and fruit weight per plant. The highest fruit production was produced in the treatment of 30 g polybag-1 (k2), namely 20.33 g; and (3) there is no interaction between NPK Mutiara fertilizer and Kayabio biofertilizer on the all observation parameters.
