An experimental field vegetative growth parameters observation was recorded on the influence of growth retardant (CCC) and Inorganic fertilizers (NPK) on vegetative growth of Chrysanthemum cv. Birbal Sahni. To investigate the optimum concentrations of Chlormequat chloride (CCC) with three levels C1, C2 and C3 i.e.1000 ppm, 5000 ppm and 10000 ppm and also three increasing levels of inorganic fertilizers (NPK) i.e. NPK1 (100 kg N2 + 60 kg P2O5 + 40 kg K2O/ha), NPK2 (150 kg N2 +120 kg P2O5 + 80 kg K2O/ha) and NPK3 (200 kg N2 + 180 kg P2O5 + 120 kg K2O/ha) appreciably improved the vegetative growth of chrysanthemum. Minimum plant height (cm) were recorded at concentration of cycocel C2 (5000 ppm) while, maximum plant height (cm) with amount of NPK3 (200 kg N2 + 180 kg P2O5 + 120 kg K2O/ha) spread (cm), maximum plant spread (cm), diameter of main stem (cm), number of leaves, number of branches/plant and flower weight/plant (g) were recorded with a beneficially concentration at 5000 ppm of CCC and N3(200 kg N2 + 180 kg P2O5 + 120 kg K2O/ha) amount of inorganic fertilizers. However, combined application C2+NPK3 of CCC and NPK significantly affected the above characters of chrysanthemum cv. Birbal Sahni.
