Abstract:
A study was carried out at farmer’s field, Bagepalli taluk, Chikkaballapur district to determine the influence of integrated nutrient management on bio-chemical and quality parameters of pomegranate (Punica granatum L.) cv. Bhagwa. The experimental plot was laid out in a randomized complete block design with three replications and twelve treatments. The bio-chemical and quality parameters such as total soluble solids, titratable acidity, sugar to acid ratio, ascorbic acid, anthocyanin and phenol content, sugars content, fruit and aril colour, physiological loss in weight, fruit shelf life and organoleptic evaluation were recorded during course of the investigation. The study results indicated that, the higher values for total soluble solids (15.98 °B), fruit anthocyanin content (49.15 mg/100ml), total sugar (13.92%) reducing sugar (12.69%), fruit (a*) (48.60) and aril colour (a*) (15.86) were recorded in a plants treated with 100 per cent RDF + vermicompost (5kg/plant) + neem cake (1kg/plant) + trichokawach (100g/plant) ₊ darakshak (4ml/litre) foliar application + VAM (50g/plant) + Penicillium pinophilum (20g/plant) + seaweed extract (20g/plant) + chitosan (2g/litre) + salicylic acid (300ppm) + phosphoric acid (3ml/litre) + micronutrients through soil and foliar application + growth regulators (foliar application) (T₁₂)_. Whereas, lower acidity (0.41%), higher TSS to acid ratio (38.90), minimum physiological loss in fruit weight (25.29%), maximum fruit shelf life (33.33 days) and highest organoleptic score (overall acceptability) were reported in T₈ {(75% RDF + vermicompost (5kg/plant) + neem cake (1kg/plant) + trichokawach (100g/ plant) ₊ darakshak (4ml/litre) foliar application + VAM (50g/plant) + Penicillium pinophilum (20g/ plant)+ seaweed extract (20g/plant) + chitosan (2g/litre) + salicylic acid (300ppm) + phosphoric acid (3ml/litre) + micronutrients (soil and foliar application) + growth regulators (foliar application)}.
