Present investigations were carried out at Farmers field in Shopian district of Kashmir valley during the year 2015–2016. Pollen viability was not affected by all treatments while pollen germination was significantly high (82.32%) in the treatment of Nutrient mixture @ 2 ml/L + CPPU @ 5 ppm. The parthenocarpic fruit set increased significantly (52.69%) by the treatment GA3 @ 500 ppm + CPPU @ 5 ppm. Highest yield (298.21 kg/tree) and yield efficiency of 0.78 kg/cm2 was recorded under combined treatment of GA3 @ 500 ppm + CPPU @ 5ppm whereas return bloom was recorded highest (16.73%) under the treatment of Nutrient mixture @ 2 ml/L. It is also concluded that yield and yield efficiency is enhanced by GA3, CPPU, Solubor and Horticab in the year of their application. But in the succeeding years, both the hormones and their combinations with nutrients proved unsatisfactory due to reduced return bloom. From the present study, it is concluded that sole application of GA3 and CPPU and two nutrient formulations Solubor and Horticab (Nutrient mixture) as well as combination of these hormones with each other and with the nutrient formulations result in improvement of pollen germination, fruit set (Parthenocarpic and non-parthenocarpic), fruit size, fruit firmness as well as chemical attributes like TSS, total sugars and Vitamin-C. Also, the yield and yield efficiency is enhanced by GA3, CPPU, Solubor and Horticab in the year of their application. But in the succeeding years, both the hormones and their combinations with nutrients proved unsatisfactory due to reduced return bloom.
