Abstract: The experiment was carried out at the farmer’s field at Jhargram, Paschim Medinipur, West Bengal on 12 years old mango plant to assess the effect of growth regulators on fruit retention and physico-chemical properties of mango cv. Amrapali. The experiment was laid out in randomized block design with five treatments and four replications. The treatments were as follows- Two times spray of NAA @ 15 ppm (T1), 25 ppm (T2) and 50 ppm (T3) at 21st day interval during pea stage; NAA @ 25 ppm at pea stage followed by NAA @ 50 ppm at marbel stage (T4) and control (water spray) (T5). It was found that total number of fruits (216.50), fruit weight (224.58 g) and fruit retention (14.25 %) was highest in T3 (NAA @50 ppm) followed by T2 (NAA @25 ppm) and T1
