Polyculture is a farming system that involves growing more than one type of crop on the same plot of land simultaneously to improve land efficiency, productivity, and soil fertility. Red ginger and sweet corn can be grown in a polyculture system because their growth characteristics are mutually supportive. The use of NPK fertilizer is also important to help meet the plants’ nutrient requirements so that growth and yield remain optimal. This study aims to evaluate the effects of various doses of NPK fertilizer and organic fertilizer on the growth and yield of red ginger and sweet corn in a polyculture system. The study was conducted on agricultural land in Indralaya Utara Subdistrict, Ogan Komering Ilir Regency, South Sumatra, from September to December 2025. The method used was a Split-Plot Design, with the main plots consisting of organic fertilizer types (chicken and cattle manure) and the subplots consisting of NPK fertilizer doses (100 kg/ha, 200 kg/ha, 300 kg/ha). The experiment was conducted in three replicates, resulting in 18 plots as experimental units. The total number of plants in this study consisted of 216 sweet corn plants and 288 ginger plants, for a total of 504 plants. The best interaction was obtained from the combination of chicken manure with an NPK dose of 200 kg/ha, which produced the highest growth and yield. This study concluded that selecting the right type of organic fertilizer and NPK dose can increase the productivity of red ginger and sweet corn.
