Abstract
A field experiment on chrysanthemum cv. Birbal Sahni was conducted for revealed the Effect of NPK on vegetative growth, flowering and yield of chrysanthemum (Dendranthema grandiflora Ramat) at Department of Horticulture, C. C. S. University, Meerut, U.P., India for the field investigation with optimum amount of inorganic fertilizers with three increasing levels of NPK i.e. N1 (100 kg N2 + 60 kg P2O5 + 40 kg K2O/ ha), N2 (150 kg N2 +120 kg P2O5 + 80 kg K2O/ ha) and N3 (200 kg N2 + 180 kg P2O5 + 120 kg K2O/ ha). Maximum plant height (cm), plant spread (cm), diameter of main stem (cm), number of leaves/ plant, number of branches/ plant, number of flowers/ plant, flower weight/ plant (g), Flower yield (q/ ha), shelf life (days) observed with amount of N3 (200 kg N2 + 180 kg P2O5 + 120 kg K2O/ ha) spread (cm). The minimum days recorded for days taken to appearance of first flower bud and days taken to flowering and also NPK level N3 significantly affected the flower stalk length (cm) and flower size (cm) in chrysanthemum cv. Birbal Sahni during the investigation.
