Study on the influence of Gibberellin on the development of sweet corn ear (Zea mays) was conducted. Completely Randomized Design (CRD) was employed. GA3 concentrations were 0, 100, 200, 300, 400, 500 and 1,000 ppm and the application of GA3 was daily 5 times. The result showed that that GA3 100 ppm gave the best in the longest ear at the mean of 74.5 centimeter and longest peduncle at the mean of 28.95 centimeter. The best mean weight of ear was 256.83 gram, mean perimenter of ear was 18.4 centimeter, and perimeter of ear after peeling its husk was 16.5 centimeter, and it showed significantly when compared to control (0 ppm). All treatments showed non significant of the total soluble solid (TSS). The heaviest of husk achieved from the treatment of GA3 300 ppm was of 150.16 gram which showed significant difference from that of control.
