Abstract:
A field experiment was conducted on China aster cv. Kamini during 2022 at Instructional Horticultural Farm, COA, IGKV, Raipur (C.G.). This experiment was laid out in open field in a Randomized Block Design with 10 treatments which replicated thrice. Different treatment combination of organic manures and biofertilizers was applied to assess the growth and yield characteristics of China aster. Among the various organic treatment combinations, application of 100% RDF through FYM + Ghanjeevamrit@250 kg/ha + Azotobacter@2 kg/ha + PSB@ 2 kg/ha (T5) was significantly increasing the plant growth characters viz. plant height (39.2 cm), plant spread (19.9 cm in N-S and 24.4 cm in E-W), number of primary branches plant-1 (12.40), number of leaves plant^-1 (126.4) ) and flower and yield parameters viz. days taken to first flower bud appearance (96.27 days), days taken to 50% flowering (122.4 days), diameter of flower (3.74 cm), number of flowers plant^-1 (34.33), fresh weight of flowers plant^-1 (41.67 g), average weight of flower plant^-1 (1.30 g), flower yield plot^-1 (0.50 kg), flowers yield ha^-1 (41.67 q), period of flowering (14.17 days). From the above experiment, it may be judged that, the application 100% RDF through FYM + Ghanjeevamrit@250 kg/ha + Azotobacter@2 kg/ha + PSB@ 2 kg/ha (T5) enhanced the growth, flowering and yield of China aster.
