Abstract
The present investigation was conducted on China aster (Callistephus chinensis L. Nees) cv. Ostrich Feather at the Main Experiment Station, Department of Horticulture, Narendra Deva University of Agriculture & Technology, Kumarganj, Faizabad (U.P.) during the year 2013-14. The experiment was laid out in Randomized Block Design with 10 treatments comprising of three levels each of GA3, NAA and ethrel and a control replicated three times. The observations were recorded for flowering and yield attributing character of China aster cv. Ostrich Feather. The foliar spraying of plant growth regulators GA3, NAA and ethrel was done 30 days after transplanting. The maximum flower stalk length (25.87 cm), diameter of flower (8.40 cm), flower yield per plant (146.27g) as well as flower yield per hectare (130.02g) were recorded with the foliar application of GA3 300ppm and minimum values were recorded in control (water spray).
