To realize the productivity potential of pomegranate cv. Bhagwa, studies were conducted on the effects of chemicals Nitrobenzene (1.0, 1.5 and 2.0 ml plant-1), Cycocel (500, 1000 and 1500 ppm plant-1) and Uracil (25 and 50 ppm plant-1) on flowering behavior and fruit yield during the years 2016-17. Highest number of hermaphrodite flowers (264.66), fruit yield (27.10 kg tree-1 and 18.86 t ha-1) and fruit number tree-1 (154) were realized with application of uracil @ 50 ppm. However, the uracil treatment did not influence significantly the number of male and intermediate flowers. Application of Cycocel @ 1000 ppm in combination with Uracil @ 25 ppm plant-1 has recorded highest fruit weight (197.55g). At flowering stage, the gas exchange parameters like the photosynthetic rate (16.48 μmol m-2 s-1) was higher in plants treated with Uracil @ 50 ppm while transpiration rate was higher (7.72 mmol m-2 s-1) with uracil @ 25 ppm. Higher stomatal conductance (0.44 mol m-2 s-1) was recorded under nitrobenzene @ 1.5ml plant-1 treatment. During fruit set stage, photosynthetic rate was high (12.55 μmol m-2 s-1) in plants treated with nitrobenzene @ 1.5 ml plant-1 whereas, transpiration rate (6.19 mmol m-2 s-1) and stomatal conductance (0.18 mol m-2 s-1) were higher in plants treated with Cycocel @ 1000 ppm + Uracil @ 25 ppm plant-1. Thus Uracil @ 50 ppm alone seems to be effective in enhancing fruit yield and the beneficial effects were associated following increases in gas exchange parameters and bisexual flowers.
