The study investigates the effects of various priming treatments on the germination and seedling growth of the Rato Basmati rice variety. Results indicate that Gibberellin at 10 mg/L produced the highest germination percentage (100%) and germination index, while Gibberellin at 15 mg/L yielded the greatest vigor index and seedling lengths. The research suggests that both Gibberellin treatments are effective for enhancing germination compared to other methods.
