Assessment of planting dates, GA₃ concentrations and Azotobacter on Chandler strawberry

The present three-factor experiment consisting of 08 treatments on strawberry cultivar Chandler at four different dates viz., 15^th August, 5^th September, 25^th September and 15^th October with the application of four GA₃ concentrations viz., no GA₃ (without application), 50 ppm GA₃, 75 ppm GA₃, 100 ppm GA₃, with and without Azotobacter (bio fertilizer) were carried out during 2018–19. The treatment under 15^th October planting date, 75 ppm GA₃ concentration and plant treated with Azotobacter (bio fertilizer) was found the most effective for majority traits viz., plant height (33.11 cm), number of runners/plant (8.25), days taken to first flower initiation (54.23), fruit setting % (88.66), fruit length (34.47 mm), fruit diameter (23.12 mm), fruit volume (15.25 ml), fresh wt. of fruit (15.34 g), fruit yield/plant (298.56 g), T.S.S. (8.52⁰Brix), vitamin C (66.51 mg/100g), and sugar content (6.970%) whereas the minimum values for most of the characters was noted with 15^th August planting date and without application of GA₃ and Azotobacter.
