Effect of NPK on Growth and Flower Yield of Hibiscus (Hibiscus rosa-sinensis)

The research work on “Effect of NPK on growth and flower yield Hibiscus rosa sinensis” was conducted in the Horticulture Research Farm, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during the year 2019-2020. The experiment was conducted in randomized block design with three replications & 12 treatments. Treatments were allocated randomly to each replication each treatment comprised of one plants which made a total of 36 plants. The best results were achieved in treatment T4 NPK (100:105:105) gram per plant with maximum plant height (113.62), maximum number of leaves per plant (71.99), maximum number of branches per plant (10.07), minimum days to bud initiation (43.31 days), minimum days taken flowering (49.87 days), maximum number of flower per plant(15.83), maximum flower diameter(cm) (13.06), flower weight(g) was found maximum (3.82), number of flower was found maximum (39575) along with maximum cost-benefit ratio (1: 1.46).
