The present investigation “Studies on the effect of biostimulants on growth and flowering of cut gladiolus (Gladiolus grandiflorus L.) Cv. Arkaamar” was carried out at the Floricultural Research Station, Rajendranagar of Sri Konda Laxman Telangana State Horticultural University, Hyderabad during September 2017 to February, 2018. The experiment was laid out in Randomized Block Design replicated thrice with eleven treatments. The results on vegetative parameters revealed that among different pre soaking and foliar sprays of bio stimulants at 30 and 45 days after corm sprouting. The application of Humic acid at 4ml/l(T8) recorded significantly minimum number of days for 50% and 100% sprouting of corms(7.20 days), maximum plant height at 30, 45 and 60 days after corm sprouting (32.93 cm, 51.26 cm and 81.53cm respectively), longer leaf length(39.80 cm) and broader leaf width with respect to floral parameters except diameter of spike. Humic acid 4ml/l treatment resulted in earlier spike emergence (57.23 days), longer spike length, more number of florets per spike (13.60), increased length (9.90 cm) and diameter of floret, fresh weight of floret (3.73 g), duration of flowering(16.53 days), spike longevity on the plant, number of spikes plant-1, number spikes per plot and further maximum number of spikes ha-1(1.83 lakhs) was also recorded.
