In this paper, the effect of Gibberellic acid on the weight of fruit bunches of Oil palm was assessed. The results showed a varying trend in the weights of Oil palm bunches present under all the treatments before 15 days of the fruit harvest. There was no significant difference in the weights of Oil palm fruit bunches in the treatments that were given 30 days prior to the harvest. Thus, the comparative assessment shows at par action of the Gibberellic acid on increase in the weights of Oil palm fruit bunches with time of application. On temporal scale, all the treatments of Gibberellic acid showed a similar action and were found to be effective in enhancing the weights of Oil palm fruit bunches. The weight of the Oil palm fruit bunches was more in the treatments with Gibberellic acid before 15 days. The treatments with 1ml/l and 2ml/l were almost the same. The comparison reveals the effectiveness of Gibberellic acid in increasing the weights of Oil palm fruit bunches. https://www.biotech-asia.org/vol7no1/effect-of-gibbrellic-acid-on-the-yield-of-oil-palm/ Oil palm; Gibberellic acid; Fruit yield.
