Effect of Pollinator Attractants and Chemicals on Mango

The present study entitled "Effect of pollinator attractants, chemicals and growth regulators on pollination, fruit set and yield of mango (Mangifera indica L.) cv. Kesar" was conducted at Fruit Research Station, Lalbaug, JAU, Junagadh during 2022-23 and 2023-24 under the South Saurashtra Agro-climatic Zone. The experiment comprised ten treatments in RBD with three replications. Among treatments, foliar spray of NAA 50 ppm + micronutrient mixture Grade-IV @ 1% (T8) showed significantly superior results in terms of higher number of hermaphrodite flowers, fruit set at different stages, yield (94.22 kg/tree and 9.42 t/ha), fruit size, and quality. T9 (NAA 25 ppm + boric acid @ 0.2%) recorded highest TSS (23.60 Brix) and sugar content, while T7 (potassium citrate 2% + putrescine 10 ppm) improved shelf life (14.40 days). Maximum net return (Rs. 3,01,118) and BCR (1.77) were noted with T8. Hence, foliar application of T8 at 50%, 75%, and 100% flowering stages is recommended for higher productivity and profitability in mango cv. Kesar.
