The investigations on fruit set and fruit drop in sweet lime (Citrus limettioides TANAKA) were carried out under Delhi conditions (North India) during the year 1962-64, at the Indian Agricultural Research Institute. The effect of GA, 4-CPA, 2, 4-D and 2, 4, 5-T at different concentrations on fruit set, fruit drop and quality of sweet lime was studied. Gibberellic acid (750 and 1, 000ppm) gave the maximum fruit set followed by 2, 4, 5-T (20ppm), GA (500 ppm) and 2, 4, 5-T (7.5 and 10ppm).
Plant growth regulator treatments proved ineffective against June drop. However, 2, 4-D (7.5 and 20ppm) and 2, 4, 5-T (7.5, 10 and 20ppm) proved most effective against pre-harvest drop.
