Abstract

The investigation was carried out at Horticultural Research Center, Patharchatta, G. B. Pant University of Agriculture and Technology, Pantnagar, (Uttarakhand), during the year 2020-2021. The experiment was laid out in Randomized Block Design (RBD) with 12 treatments (T1 : Nimbecidine @ 0.4%, T2 : Kunapajala @ 10%, T3 : Starch @ 1%, T4 : Starch @ 2%, T5 : Mineral oil @ 0.5%, T6 : Mineral oil @ 1.0%, T7 : Starch @ 1 % + Mineral oil @ 0.5%, T8 : Sodium bicarbonate @ 1% + mineral oil @ 0.5%, T9 : Nutrients mixture (boric acid @ 0.2% + calcium nitrate @ 0.2% + zinc sulphate @ 0.2%), T10: Fruit bagging (ordinary brown paper), T11: Fruit bagging (organic / UV/ water resistant brown paper), T12: Control) and the treatment were replicated thrice. The results of the study revealed that the treatment T11 (fruit bagging with organic / UV/ water resistant brown paper bags), was found to be most effective for increasing the yield (14.58 kg plant-1, 19.43 tonnes hectare-1), fruit weight (298.23g), shelf life (15.05 days), TSS (20.95 ºB), total sugars (16.86%), reducing sugar (5.20%) and total carotenoids (5.86 mg/ 100g). The net return (737027.2 Rs/ha) was also observed higher with the treatment T11. Thus, fruit bagging with organic /UV / water resistant brown paper bags was found most effective for increasing the yield, shelf life, quality and net return in late maturing mango cv. Amrapali.
