Effect of CPPU (Forchlorfenuron) on fruit retention and postharvest quality of ‘Alphonso’ mango

Fruit drop is a major problem in mango. In order to reduce fruit drop CPPU (Forchlorfenuron) is widely used in fruit industry. To increase fruit retention trial were conducted to evaluate the effect of CPPU (Forchlorfenuron) on fruit retention and postharvest quality of 'Alphonso' mango. The present investigation was carried out in three locations in Konkan region in RBD with five treatments and 4 replications. CPPU was sprayed at a dose of 1, 2, 3, 4 ppm at the peanut and marble stage and water as control. It was observed that CPPU sprayed trees showed significantly more fruit retention and total number of fruit at harvest as compared to the control treatment. The highest yield was recorded in 3 ppm CPPU treatment at Dapoli and Roha and 4 ppm treatment at Rameshwar location. There were no significant effects on quality of fruit of CPPU trees and control fruit.
