Influence of foliar application of gibberellic acid and nutrients on yield and yield attributes of pomegranate cv. Bhagwa under northern dry zone of Karnataka

Abstract

The investigation was conducted in the farmer’s field of Tulasigiri village, in Bagalkot taluk Bagalkot district during 2017-18 with an objective to study the effect of foliar application of gibberellic acid and nutrients on yield and economics of pomegranate cv. Bhagwa. The experiment consisted of sixteen treatments with three replications laid out in Randomized Block Design. Among the different treatments, foliar application of GA3 @ 100 ppm + CaCl2 2% + borax 0.2% + MgSO4 0.5% has recorded the highest fruit length (93.74 mm), fruit diameter (92.38 mm), fruit volume (387.63 ml), number of arils (594.60), total aril weight (232.98 g), peel weight (136.02 g), fruit weight (363.55 g), yield per plant (28.90 kg) and yield per hectare (21.38 t/ha) compared to control which recorded lowest yield (16.57 t/ha) and yield attributes. Highest B:C was obtained in T13 (3.23) and T15 (3.22). Among the different treatments, the plants treated with GA3 @ 100 ppm + CaCl2 2% + borax 0.2% + MgSO4 0.5% influenced the improved fruit growth, increased yield and better B:C as compared to other treatments.
