A field experiment entitled efficacy of pruning intensities and nutrients spray on growth and quality parameters of Pomegranate (Punica granatum L.) cv. Bhagwa was conducted at Fruit Research Station, Imaliya, Department of Horticulture, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.) during 2020-21. Total of 20 treatments combinations of pruning intensity and foliar spray of nutrient were arrange in AFRBD. The pruning intensity and foliar spray of nutrients significantly influence the growth and chemical composition of fruits. The maximum plant height (40.64 cm), shoot length (32.51cm), shoot diameter (2.59 mm) at 90 days after pruning and minimum days taken to first flowering (98.60 days), to first fruit set (115.47 days) and highest number of flowers per shoot (7.21) were recorded under pruning at 20 cm whereas, maximum juice content (52.27 %), TSS (15.32 °Brix), reducing sugar (12.35 % ), total sugars (12.93 % ) and minimum non-reducing sugar (0.87 % ), and acidity (0.36 % ) were recorded under pruning at 60 cm. Similarly, the foliar spray of nutrient bring out significant changes in the growth and quality parameters of the fruits and maximum plant height (39.40 cm), shoot length (30.96), shoot diameter (2.57 mm) at 90 days after pruning and least days were taken to first flowering (100.17), to first fruit set (118 days) and higher number of flowers per shoot (6.58) as well as higher value of juice contain (51.93%), TSS (15.37 0B), reducing sugar (11.74 %), total sugars (12.91 %) and minimum value of non-reducing sugar (0.98 %) and acidity (0.41%) were recorded under the application of 2% Urea + 0.4% Zn + 0.4% B. As regarded, the interaction effect of pruning intensities and foliar application of nutrients showed significant effect on the growth and quality parameters of the fruits and the maximum plant height (47.84 cm), shoot length (34.93 cm), shoot diameter ( 2.66 mm) were recorded at 90 days after pruning as well as minimum day to first flower (95 days), to first fruit set (112.33 days) and maximum number of flowers per shoot (7.80), were recorded with 20 cm pruning in combination with 2% Urea + 0.4% Zn + 0.4% B. As regard the chemical composition of fruit the maximum juice content (55.00 %) and TSS (15.80 °Brix) were recorded under treatment 60 cm pruning along with the foliar spray of Urea (2%) + Zn (0.4%) + B (0.4 %). The quality parameter viz. acidity (0.30%), reducing sugar (12.91 %), non-reducing sugar (0.74 %), total sugars (13.96 %) were recorded under treatment 60 cm pruning along with the foliar spray of Urea (2%) + Zn (0.4%) + B (0.4 %) and did not differ significantly.

Growth, Pomegranate, Quality, Bahar

All the pruning intensities and nutrient application of treatments were found better than control in terms of growth and chemical characteristics of fruit. The pruning intensity of 20 cm was found superior to increase the growth parameters of the fruits and the pruning intensity of 60 cm was found superior for quality parameters of the fruits. As regards to nutrients, then the application of Urea (2%) + Zn (0.4%) + B (0.4%), was found to be superior for both the growth and quality parameters of the fruits. Among the interaction the pruning intensity of 20 cm along with the application of 2% Urea+0.4% Zn+0.4% B, was found to be superior for the growth parameters of the fruits and the treatment pruning at 60 cm along with the application of 2% Urea+0.4% Zn+0.4% B, was found superior to increase the chemical parameters of the fruits.
