Abstract: This study was conducted to determine the effect of biostimulants on growth, flowering and yield of Chrysanthemum cv. Kolar local with thirteen treatments such as two concentrations of biostimulants sprayed at four frequencies (first, second, third and fourth spray at 30, 60, 90 and 120 days after transplanting) and untreated control. Each treatment was replicated thrice in randomized complete block design (RCBD). The parameters such as plant height (cm), number of leaves, leaf area (cm2), stem girth (mm), number of primary branches, number of secondary branches and intermodal length were checked as morphological parameters. Moreover, days taken for first flowering, days to 50% flowering and duration of flowering are the checked flowering parameters whereas number of flowers per plant, flower yield per plant, flower yield per m2, flower yield per hectare and sucker yield per plant are the yield parameters. Among the different treatments, Spic cytozyme@ 0.4% (T8) registered maximum plant height (89.04 cm) and intermodal length(2.44 cm), whereas biovita @ 0.6% recorded the maximum number of leaves (143.43), leaf area per plant, (5245.33cm2), stem girth (8.18 mm), number of primary (11.47) and secondary branches (24.98). Regarding the flowering parameters; among different treatments, minimum number of days to first flower initiation (100.00) and 50 percent flowering (112.33) and maximum flower duration (65.82) was recorded with Biovita @ 0.6%(T4). However, control (T13) recorded minimum.
