Abstract: The present investigation “Studies on the effect of bio stimulants on growth, flowering, yield and postharvest vase life of gladiolus (Gladiolus grandiflorus L.) Cv. Arka amar” was carried out at the Floricultural Research Station, (Agricultural Research Institute) Rajendranagar of Sri Konda Laxman Telangana State Horticultural University, Hyderabad during September 2017 to February, 2018. The experiment was conducted in a 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 i.e T8 recorded significantly minimum number of days for 50 per cent and 100 per cent sprouting of corms (7.20 and 12.40 respectively), maximum plant height (32.93 cm, 51.26 cm and 81.53 cm) at 30, 45 and 60 days after corm sprouting respectively, longer leaf length (39.80 cm) and broader leaf width (3.73 cm) was also recorded in this treatment. While there is no significant different among the treatments with regard to the number of leaves plant-1 (7.16) recorded at the flowering time. Significant variations were observed among different bio stimulants application with respect to floral parameters except for diameter of spike (3.73cm). Among various inputs, Humic acid at 4ml/L-T8 resulted in earlier spike emergence (57.23 days), spike length (96.90 cm), number of florets per spike (13.60), length of floret (9.90 cm), diameter of 2nd fully opened floret (8.73cm), fresh weight of floret (3.73 g), duration of flowering (16.53 days), spike longevity on the plant (18.32 days), number of spikes plant-1 (2.0), number spikes per plot (41.33) and further maximum number of spikes ha-1 (1.83 lakhs) was also recorded in this treatment. With respect to corm and cormel attributes, pre soaking and foliar application of Humic acid at 4ml/L i.e T8 resulted in significantly maximum corm weight (54.83 g), corm diameter (5.13 cm), cormel size (2.46 cm), maximum number of corms plant-1 (2.80), higher number of corms plot-1 (39.90), higher number of corms ha-1 (1.77 lakh).Further maximum cormels plant-1(18.56), cormels yied plot-1 (360.46 g) and cormels yield ha-1 (165.94 kg) was also recorded in this treatment. In the postharvest studies, among the bio stimulant treatments Humic Acid at 4ml/L registered significantly best results for almost all the postharvest and physiological parameters studied expect for water balance, interaction between treatments and days were non significant. Significantly longer vase life of spike (10.43 days), highest number of days taken for 50 per cent floret opening (5.40), maximum number of days taken to 100 per cent floret opening (9.10), minimum change in fresh weight (89.54 %), higher water uptake (18.20 g.spike-1), transpiration loss of water (17.97 g.spike-1) while, minimum percent of spoilage of floret (39.08) was recorded in Humic acid at 4ml/L treatment during vase life period. Taking into account of all the aspects of bio stimulants pre soaking of corms before planting and foliar sprays at 30 and 45 days after corm sprouting treatment effect, it was concluded that, the treatment Humic Acid at 4ml/L i.e T8 was beneficial to obtain maximum number of spike and net returns and appears to be an optimum treatment for enhancing growth, flowering, yield and postharvest vase life in cut gladiolus Cv. Arka amar
