Abstract. This study aims to determine the effect of NPK and ZPT Gobest fertilizers on the growth of cayenne pepper plants (Capsicum frutescens L.). The experiment was carried out using a Group Random Design (RAK) with two factors, namely the dose of NPK fertilizer (100 kg/ha, 150 kg/ha, and 200 kg/ha) and the concentration of ZPT Gobest (1 ml/liter, 2 ml/liter, and 3 ml/liter) which was repeated for three replicates. The parameters observed included plant height, number of leaves, leaf area, and number of branches. The results showed that the application of 200 kg/ha NPK fertilizer and 2 ml/liter ZPT Gobest had the best influence on plant vegetative growth, such as plant height and number of leaves, leaf area, and number of branches.
