Abstract: The present investigation entitled “Effect of plant growth regulators on flowering, fruit set and yield of custard apple (Annona squamosa L.)†was carried out on located farmers field at Malegaon Tal. Badnapur, Dist-Jalna during the year 2016- 2017. The experiment was laid out in Randomized Block Design with ten treatments of plant growth regulators which were replicated three times. The results revealed that, maximum number of flower per shoot (28.11) was found with spraying of NAA @ 100 ppm (T3). While, the highest percentage of fruit set (70.13 %), lowest percentage of fruit drop (15.78 %), maximum number of fruits per plant (59.83), fruit weight (186.35 g.), maximum fruit yield (11.18 kg/plant) and the maximum fruit yield (44.72 qt/ha) was recorded in treatment of GA3 @ 75 ppm (T5), significantly the minimum days (111.00 days) required for flowering to harvesting was recorded in treatment of Ethrel @ 300 ppm (T9).
