Abstract: An investigation on “Effect of foliar application of chemicals on yield and quality of pomegranate (Punica granatum L.) cv. Bhagwa.†was undertaken with objective, To enhance the yield and quality of pomegranate by foliar application of various chemicals. The field study was carried out on the field of Horticulture (pomology) VNMKV, Parbhani. The experiment was laid out in Randomized Block Design (RBD) with Ten treatments viz., T1 NAA (40 ppm) + Boron (0.3%), T2 NAA (40 ppm) + CaCl2 (1.5%), T3 NAA (40 ppm) + ZnSO4 (0.2%), T4 GA3 (75 ppm) + Boron (0.3%), T5 GA3 (75 ppm) + CaCl2(1.5%), T6 GA3 (75 ppm) + ZnSO4 (0.2%), T7 2,4-D (20 ppm) + Boron (0.3%), T8 2,4-D (20 ppm) + CaCl2 (1.5%),T9 2,4-D (20 ppm) + ZnSO4 (0.2%), T10 control with three replications. Observations on yield attributes of individual treatments were recorded.The results obtained for yield parameters and quality parameters had significant and non-significant influence due to foliar application of various chemicals in given treatments.Among these treatments fruit attributes such as length of fruit (8.71 cm), diameter of fruit (9.40 cm), and volume of fruit (334.40 ml), were found maximum in treatment T4 i.e. spraying of GA3 (75 ppm) + Boron (0.3%) which were respectively 14.16 per cent, 18.98 per cent, 47.80 per cent more as compared to control. Aril attributes such as number of aril in 100 g (416.00), aril percentage (76.74%), aril to rind ratio (2.40) and number of aril per fruit (864.00). The rind attributes i.e. rind thickness and rind percentage was increase treatment T10 i.e. control (1.84 mm), (38.15%) respectively. Given treatments also enhanced the yield attributes i.e. average weight (310.11 g), number of fruit per plant (111.25), weight of fruit per plant (34.49 kg) and yield mt/ha (19.14 mt/ha) in the treatment T4 i.e. spraying of GA3 (75 ppm) + Boron (0.3%) which were respectively 28.03 per cent, 63.60 per cent, 109.53 per cent and 109.40 per cent more as compared to control.Close analysis of the present investigation revealed that the foliar application of alone or in combination with plant growth regulators and chemicals were able to increase the yield and quality characters of pomegranate cv. Bhagwa. Among the ten different treatments of sprays with superior treatment T4 i.e. spraying of GA3 (75 ppm) + Boron (0.3%) was found to be more effective in increasing the yield attributing characters respectively.
