Abstract: Present study was conducted in the farmer’s field of Hire Samshi village, in Bagalkot taluk of Bagalkot district during 2016-17 with an objective of to study the effect of foliar application of gibberellic acid and nutrients on yield and quality of pomegranate cv. Bhagwa. The Experiment was consisted of nine treatments with three replications laid in Randomised block design. Treatment details include T1- GA3 @ 50 ppm, T2- GA3 @ 100 ppm, T3- GA3 @ 50 ppm + calcium nitrate 2 %+ borax (0.2 %) + KNO3 (2 %), T4- GA3@ 50ppm + calcium nitrate 2 % + borax (0.2 %) + SOP(2 %),T5- GA3 @ 100 ppm + calcium nitrate 2 % + borax (0.2%)+ KNO3(2 %),T6 - GA3100 ppm + calcium nitrate 2 %+ borax (0.2%) + SOP (2 %), T7- Calcium nitrate 2 %+ borax (0.2%) + KNO3(2 %), T8- Calcium nitrate 2 %+ borax (0.2 %) + SOP(2 %), T9- control (water spray). Among the different treatments the foliar application of GA3@ 50 ppm + calcium nitrate 2 % + borax 0.2 % + SOP 2 % (T4) has recorded highest fruit length (94.62 mm), fruit diameter (93.63 mm), fruit volume (448.67 ml), number of arils (719.33), total aril weight (297.67g) 100 aril weight(44.00g), peel weight (156.00 g), fruit weight (431.67 g), yield per plant (44.11 Kg) and yield per hectare (34.15tonnes/ha) compared to control which recorded lower yield (26.27 t/ha) and yield attributes. With respect to quality parameters high total sugar (14.64 %), reducing sugar (12.69 %), total soluble solids (15.50o Brix) content, Sugar/acid ratio (23.33 %), ascorbic acid content (15.37 mg 100 g-) and juice (56.33%), highest shelf life (27.02 days) and least physiological loss in weight (14.28 %), where as highest physiological loss in weight (18.51 %) and minimum shelf life (20.19days) was recorded in control.
