Abstract:

A field experiment was carried out at Punjab Agricultural University, Regional Research Station, Gurdaspur during the years 2015-16 and 2016-17 to assess the influence of NAA 25, 50 ppm and 75ppm; GA3 50, 100 ppm and 150ppm; kinetin 15,30 and 45 ppm; ethrel 250, 500 ppm and 750ppm along with control on vegetative growth, yield and quality parameters of phalsa. Among all the treatments, maximum number of shoots/ plant (130.25), shoot length(4.15cm), number of leaves/shoot (72.5), internodal length (11.5cm), number of fruits/ node (21.55) and number of fruiting nodes/ shoot (20.76) were recorded with the application of GA3 at 150 ppm. Maximum fruit yield (4.85kg/plant), fruit length (1.60cm). Fruit breadth (1.72cm) and pulp weight (65.55gm) were observed in GA3 at 100ppm. Minimum stone weight (10.22g) with maximum pulp to stone ratio (37.89) was observed in GA3 100ppm. Maximum TSS (27.50°Brix) with minimum titratable acidity (2.3%) were observed with ethrel 500ppm. Maximum TSS to acidity ratio (11.96) was obtained with ethrel 500ppm. Total sugars (29.00%), reducing sugars (21.50%) and non-reducing sugars (7.50%) were significantly higher in ethrel 750ppm. Highest ascorbic acid content (44.25mg/100gm of pulp) was noticed in GA3 100ppm.Maximum shelf life (53.51hours) of fruits was observed with kinetin 30ppm.
