Abstract: The present study was conducted to determine the effect of bio-stimulants on growth, flowering and yield of Gladiolus cv. Summer Sunshine with eleven treatments such as two concentrations of bio-stimulants sprayed at three frequencies (first, second and third spray at 30, 45 and 60 days after planting) 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), and leaf area index, were checked as vegetative parameters. Moreover, days taken for initiation of inflorescence, days taken for first floret opening, days to 50% flowering and duration of flowering are the checked flowering parameters whereas number of spikes per plant, spike yield per plot and spike yield per hectare are the yield parameters. Among the different treatments, Biozyme @ 0.4% registered maximum plant height (76.07 cm), maximum number of leaves (11.33), leaf area (1251.96 cm2) and leaf area index (2.09). Regarding the flowering parameters; among different treatments, minimum number of days taken for initiation of inflorescence (75.00 days) days taken for first floret opening (80.67days), days to 50% flowering (84.67days) and duration of flowering (22.00 days) was recorded in Biozyme at 0.4 per cent. And yield parameters number of spikes per plant (1.51), spike yield per plot (45.30) and spike yield per hectare (2,26,500.00) recorded in Biozyme at 0.4 per cent. However, control recorded minimum in all the parameters.
