Abstract: This study was conducted to assess the Influence of Bulb treatment with Bio-Fertilizers and foliar spray of Bio-Stimulants on growth and flowering of Tuberose (Polianthes tuberosa L.) cv. Suvasini. The experiment was laid out in Contrast Factorial Randomised Blocked Design consisting of two factors with three and eight levels respectively. Replicated thrice at SKLTSHU, college of horticulture, Mojerla. Tuberose bulbs where treated with three Bio-Fertilizers viz., phosphate solubilizing bacteria (PSB), Azospirillum (AZO) and Potassium solubilizing bacteria (KSB) each 200 g/l and they are foliar sprayed by eight Bio-Stimulants gibberellic acid (GA3), salicylic acid (SA), cycocel (CCC) and humic acid (HA) each at 200 ppm and 400 ppm. Among bio fertilizers PSB (Phosphate solubilizing bacteria) and among bio stimulants GA3 400 ppm. while in interaction effect PSB (Phosphate solubilizing bacteria) 200 g/l along with GA3 (Gibberellic acid) 400 ppm has resulted significantly best in Plant height (cm), Number of leaves per plant, Length of leaf (cm), Days taken to spike emergence, Spike length (cm), Diameter of spike (cm), Rachis length (cm), Number of florets per spike, Number of spikes per plant, Flower longevity (days), Flower yield or spike yield per hectare (in lakhs), when compared with other treatment combinations and control.
