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

Abstract

The present three-factor experiment consisting of 08 treatments on strawberry cultivar Chandler at four different dates viz., 15th August, 5th September, 25th September and 15th 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 15th 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 15th August planting date and without application of GA3 and Azotobacter.
