Title : Studies on standardization of pruning intensities and concentrations of chemical defoliants in improving yield and fruit quality of pomegranate (Punica granatum L.) cv. Bhagwa

Abstract :

An experiment with an objective to standardize the concentrations of chemical defoliants pruning intensities for maximum yield and fruit quality of pomegranate (Punica granatum L.) cv. Bhagwa was conducted during 2020-21 & 2021-22 at pomegranate orchard under hi-tech horticulture, College of Agriculture, Khandwa (M.P.). The experiment was laid out in Randomized Block Design with three replications with pomegranate plants planted at a distance of 3m X 2.5 m. The experiment comprised of 16 treatments consisting of different levels of chemical defoliants and pruning intensities. Number of fruits per plant, Fruit weight (g), Fruit volume (ml), Fruit yield per plant (kg), Fruit Yield per hectare (q) also showed significant effect of the treatments. Maximum number of fruits per plant (63.50), Maximum fruit weight (164.17 g), Maximum fruit volume (287.50 ml), Fruit yield per plant and fruit yield per hectare (10.42 kg and 173.65 q) was recorded under the treatment T15. Physico-chemical or quality parameters like Number of arils per fruit, Aril: rind ratio, Juice (%), TSS (ºBrix), Titratable acidity (%), Total sugar (%), TSS: Acid ratio, Reducing Sugar (%), Non-reducing Sugar (%) varied significantly with the treatments. Maximum number of arils per fruit (679.17), Maximum Aril: rind ratio (2.44), maximum juice percentage (56.33), Maximum TSS (14.59 °Brix), Minimum titratable acidity (0.31%), Maximum total sugar (6.38%), Maximum TSS: Acid ratio (47.74), Maximum reducing (4.76%) and non-reducing sugar (1.95%) was recorded under the treatment T15An experiment with an objective to standardize the concentrations of chemical defoliants pruning intensities for maximum yield and fruit quality of pomegranate (Punica granatum L.) cv.
