The present experiment was conducted on three varieties of china aster viz., Shashank, ArkaArchana and ArkaAadya grown in pots at the Department of Floriculture and Landscaping, College of Agriculture, OUAT, Bhubaneswar during 2016-17 in order to ascertain the influence of foliar application of gibberellic acid (GA3) on growth, flowering and yield. The treatments of foliar spray of GA3 (50, 100 and 150 ppm) was given with different spray frequencies (twice and thrice). Plants of variety ArkaAadya performed significantly better than varieties ArkaArchana and Shashank for number of leaves and number of flowers. However, days to bud initiation, bud showing colour and first flowering were earliest in variety ArkaArchana. Tallest plant with maximum number of primary branches was recorded in variety Shashank. Three times application of GA3 at 100 ppm recorded maximum plant height, number of primary branches, number of leaves, number of flowers and duration of flowering. Days to bud initiation, bud showing colour and flowering were earliest when sprayed thrice with 100 ppm GA3.
