Abstract: An investigation was carried out on 19 years old plantation of mango (Mangifera indica L.) cv. Amrapali at C.S.A.U.A.&T., Kanpur (U.P.) India, during the year 2013-2014. In all, 15 treatments foliar application of plant bio-regulators and micronutrient were tested in RBD design replicated thrice. The result concluded that pre-harvest application of GA3 (40 ppm) + ZnSO4 (1.0%) results in significant decrease in fruit drops, increase in fruit retention. The application of NAA (40 ppm) + ZnSO4 (0.5%) results in significantly increase the number of fruits set per plant and minimum fruit set under control.
Keywords: Mango, GA3, NAA, Zinc sulphate, fruit drop
