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.
