An experiment was conducted to assess the effect of NAA (10, 15 and 20 ppm), GA3 (50, 75 and 100 ppm) and boric acid (0.1, 0.2 and 0.3%) on vegetative growth, yield and quality of strawberry Cv. Chandler. Acqueous solution of these plant bio-regulators and micronutrient were sprayed on the plants twice, first at 25 days after transplanting and secondly at bud initiation stage (65 days after transplanting) during the year 2003. Observed data clearly revealed that plants treated with GA3 at 100 ppm produced tallest plants (20.50ppm) with highest number of leaves (18.75), maximum number of crowns (3.50), runners (3.50), flowers (16.13), fruits set (15.10), berry length (3.14cm) berry width (1.95cm) and yield (110.68g) per plant. Significantly longer duration of harvesting (67.95 days) was also recorded in the plants treated with GA3 at 100 ppm. As the quality parameters are concerned, plants treated with NAA at 20 ppm produced berries with maximum TSS (7.68° Brix), total sugars (5.97%) and titratable acidity (0.92%) contents, whereas the ascorbic acid content was maximum (56.66mg) in the berries of plants treated with GA3 at 100 ppm.
