This study aims to determine the effect of gibberellin seed priming and coconut coir ash fertilizer on growth, carbohydrate accumulation and productivity of Bima pulut corn. The research was conducted using a randomized block design. The main plot was seed priming with gibberellin concentrations of 0, 150, and 300 ppm, and as a sub plot was coconut coir ash fertilizer of 0.00; 0.75; 1.50; 3.00 g/kg. Each treatment was done in three replications. Data were analyzed using separate plot ANOVA with treatment arranged in a factorial. If the treatment is significantly different, Tukey’s honestly significant difference test will be carried out. The results showed that the interaction of gibberellin (GA3) and coconut coir ash fertilizer had a significant effect on plant height, productivity without corn husks kg/ha, and amylose content but had no significant effect on leaf number, number of cobs per-plant, cob length, number of row of seeds per cob, weight of cob with and without corn husks.
