Abstract
Sweet corn (Zea mays L. saccharata Sturt) is a high-potential horticultural commodity in Indonesia. The demand for sweet corn is increasing due to growing awareness of its high nutritional content. The application of the plant growth regulator paclobutrazol and urea fertilizer can help enhance sweet corn yields. This research was conducted in Megeri Village, Kradenan Sub-district, Blora Regency, Central Java, from November 2024 to January 2025. The experimental method used was a Split Plot Design (SPD) with two factors: paclobutrazol concentrations (K0 = 0 ppm, K1 = 1000 ppm, K2 = 1500 ppm, and K3 = 2000 ppm) and urea fertilizer doses (D1 = 150 kg/ha, D2 = 250 kg/ha, D3 = 300 kg/ha, and D4 = 350 kg/ha). The experiment was carried out with three replications. Data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test at the 5% level. A significant interaction occurred between the 1500 ppm paclobutrazol concentration and 300 kg/ha urea dose, producing the best results, particularly in plant height at 28–42 days after planting, stem diameter of 22.50 mm, ear length without husk of 23.13 cm, and fresh ear weight with husk of 301.22 g and without husk of 277.33 g. Keywords: Growth, Paclobutrazol, Urea Fertilizer, Sweet Corn
