Effect of pre harvest application of plant growth regulators on yield of pomegranate (Punica granatum L.) CV. Bhagawa

Abstract

The present investigation was carried out at Department of Horticulture, VNMKV, Parbhani during Mrig bahar of the year 2017-18 and 2018-19. The experiment was laid out in Randomized Block Design (RBD) with thirteen treatments replicated thrice. Three foliar sprays of all the treatments given at 45, 90 and 135 days after flowering and observations were recorded. The results of the investigation revealed that, amongst the different treatments GA3 100 ppm recorded maximum length of fruit (8.94 cm), diameter of fruit (8.06 cm), and volume of fruit (253.74 ml ), number of fruits per plant (78.83), average weight of fruit (298.52 g), yield per plant (23.05 kg), yield per hectare (17.06 Mt/ ha), weight of arils per fruit (232.86 g), weight of 100 arils (50.75 g) while treatment control recorded minimum values for all above parameters. The treatment Spermidine 15.0 mM/Lit exhibited significantly maximum rind thickness (3.30 mm) and rind weight (66.08 g) over rest of the treatments while minimum rind thickness (2.41 mm) and rind weight (48.53 g) was observed in treatment control and treatment 6BA respectively.
