Influence of biostimulants on growth and yield of China aster (Callistephus chinensis) cv. Poornima

Dr. A Vidya, Aishwarya Shivpure and BG Hanumantharayya
China aster (Callistephus chinensis L. Nees.) is an important commercial ornamental annual flower plant. A field experiment was conducted to study the efficacy of biostimulants on performance and flower quality of China aster cv. Poornima at Department of Horticulture, College of Agriculture, University of Agricultural Sciences, GKVK, Bengaluru. The experiment was laid out in randomized complete block design (RCBD) with three biostimulants via., Boron, Humicil and Azospirillum at two different concentrations all together as treatments and was replicated thrice. The plants sprayed with FYM + RDF + humic acid at 1.0 per cent recorded maximum plant height (61.50 cm), number of leaves (164.81), leaf area (18.53 cm2), stem girth (12.01 mm), number of primary branches (17.28) and secondary branches per plant (32.95), internodal length (7.04 cm), days to first flowering (59.44 days), days taken for 50 per cent flowering (67.22) and duration of flowering (70.33 days). With respect to number of buds per plant (43.67), number of flowers per plant (40.00), flower yield per plant (160g/plant), flower yield per square meter (1777.6 g/plant) and flower yield per hectare (17.7kg/ha).
