increased fruit set in Upland cotton (Gossypium hirsutum L.) by applying a solution of 100 ppm of gibberellic acid to the flowers at anthesis. Arndt* using foliar application of potassium gibberellate did not find any effect on fruit retention. Rates up to 1 gram per acre were applied weekly for 6 weeks. Dransfield (1) found a single spray of gibberellic acid at 10 ppm failed to increase fruit set, although shedding was delayed. Jackson and Fadda (3) reported shedding of fruit was increased by the application of gibberellic acid (up to 500 ~g. per plant) to the leaves of variety of the Gossypium barbadense species. Also, foliar application of gibberellin affects the growth and composition of stems and petioles of the cotton plant as well as the leaves (2).
