Effect of pollinator attractants, chemicals and growth regulators on pollination, fruit set and yield of mango cv. Kesar

The experiment was conducted at Fruit Research Station, Lalbaugh, Junagadh Agricultural University, Gujarat in 2022-23 to 2023-24 using a Randomized Block Design with ten treatments replicated thrice. Results showed that foliar spray of sucrose @ 10% (T3) recorded the highest number of hermaphrodite flowers per panicle (121.46) and number of fruits at grain stage (73.40). Foliar spray of NAA 25 ppm + boric acid @ 0.2% (T9) resulted in the highest number of fruits at pea stage (17.39), fruit set per cent at pea stage (23.56%), lowest fruit drop at pea stage (76.44%), highest TSS (23.60 °Brix), reducing sugar (5.25%), non-reducing sugar (10.11%), and total sugar (15.36%).The treatment with NAA 50 ppm + micronutrient mixture Grade-IV @ 1% (T8) recorded the highest fruit set per cent at grain stage (60.50%), number of fruits at marble stage (3.33), fruit set per cent at marble stage (93.91%), fruits per panicle (2.02), number of fruits per tree (330.96), yield (94.22 kg/tree, 9.42 t/ ha), net return (₹3,01,118), BCR (1.77) and lowest fruit drop at marble stage (80.94%).
