A study conducted in Malang, Indonesia, from February to June 2023, investigated the effect of eco enzyme concentration and NPK fertilizer dosage on the growth and yield of sweet potatoes in urban farming systems. Using a factorial randomized block design repeated three times, combinations of eco enzyme concentrations and NPK fertilizer doses were tested. Results showed that eco enzyme concentration affected the NPK fertilizer dose on sweet potato plants, with the highest fresh tuber weight at an NPK fertilizer dose of 3.75 g per plant produced at an eco enzyme concentration of 30 ml per liter. Eco enzyme concentrations and NPK doses were found to increase the growth and yield of sweet potato plants across variables such as leaf area, plant dry weight, tuber fresh weight, and harvest index.
