The present study was conducted with objective to know the effect of different pruning intensity and plant growth regulators on yield and quality of Gola cultivar. The present was comprised four different pruning intensity of previous season growth viz., P0 – no pruning, P1- 25 % pruning, P2- 50 % pruning, P3- 75 % pruning and plant growth regulators viz., C0-control, C1- GA3 @ 10 ppm and C2- NAA @10 ppm. Significantly higher fruit weight (23.69 g) has been recorded with 75% pruning intensity + NAA 10ppm followed by 75% pruning intensity + GA₃ 10 ppm and least being in control. The highest fruit length, volume and width has been measured with 75% pruning intensity + NAA 10ppm and lowest were in control. The maximum fruit yield (110.54 kg/plant) has been achieved by employing 50% severity of pruning with NAA 10ppm which found significantly superior over 25% pruning intensity+ NAA 10ppm and control. The highest severity of pruning (75%) has been adjudged as supra-optimal level of pruning severity (negative effect) in increasing fruit yield. Significantly higher total soluble solid has been analyzed in fruits with 50% pruning intensity + NAA 10ppm followed by 50% pruning intensity + GA₃ 10 ppm and lowest noted in control, while pulp : stone ratio was significantly by various pruning intensities and plant growth regulators and recorded maximum in 75% pruning + 10 ppm NAA followed by 75% pruning + GA₃. The maximum vitamin C content in fruits have been analyzed by 50% severity of pruning + NAA 10ppm followed by 50% pruning intensity + GA₃ 10 ppm with value was observed significant, while acidity of fruits were significant. The highest TSS : Acid ratio, reducing and non-reducing sugar and total sugar of fruits have been analyzed by 50% pruning intensity + NAA 10ppm and lowest one in control but variations were found significant in above all biochemical parameters.
