An experiment was carried out at Horticultural Farm IGKV, Raipur during 2007-08 to investigate the effect of organic manure and different concentration of gibberellic acid on growth, yield and flower quality of African marigold. The results indicated that application of 200 ppm GA3 with vermicompost and RDF increase the plant height, plant spread, number of primary branches, number of secondary branches, fresh weight of shoot and root at harvest, dry weight of shoot and root at harvest, earlier bud emergence, flowering and period for 50% flowering, pedicel length, blooming period, number and yield of flower. While, FYM with same component level increase the buds size, flower diameter and weight of individual flower. However, vase life of cut flower was maximum in 100 ppm GA3 with vermicompost and RDF.
