Seed priming and applying organic K fertilizer can involve efforts to increase local glutinous corn Bimapulut productivity. This study aims to determine the effect of gibberellin (GA3) as seed priming and coconut coir ash fertilizer on the growth, carbohydrate accumulation, and productivity of Bimapulut corn. The research was conducted using a randomized block design. The main plot was seed priming treatment with gibberellin concentrations of 0, 150, and 300 ppm. As a subplot was the treatment of coconut coir ash fertilizer with fertilizer/soil concentration of 0.00; 0.75; 1.50; 3.00 g/kg; thus, there are 12 treatment combinations. Each treatment was done in three replications. Data were analyzed using separate plot ANOVA with treatment arranged in a factorial. If the treatment is significant, Tukey’s honestly significant difference test will be carried out. The results an interaction between GA3 and coconut coir ash fertilizer 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, the weight of cob with and without corn husks.
