Abstract:
The experiment was conducted at College of Horticulture, Mojerla, Wanaparthy, SKLTSHU. Statistical design was Contrast Factorial Randomized Block Design (FRBD with Control) with two factors (Bio-Fertilizers and Bio-Stimulants) with three and eight levels respectively replicated thrice. Tuberose bulbs Cv. Suvasini were treated with Bio-Fertilizers (Phosphate Solubilizing Bacteria (PSB @ 200g/l), Azospirillum (AZO @ 200g/l), Phosphate solubilizing Bacteria (KSB @ 200g/l)) and were sown in the filed with ridges and furrow method of plots. 20 days after sowing when the bulbs were sprouted, they are foliar sprayed with Bio-Stimulants (Gibberellic acid (GA₃), salicylic acid (SA), cycocel (CCCC), Humic acid (HA) each at 200 ppm and 400 ppm). After harvest of the spikes the post-harvest studies were done such as vase life, transpiration loss, water uptake. Among the treatments PSB in Bio-Fertilizers, GA₃ 400ppm in Bio-Stimulants while in the interaction effect of Bio-Fertilizers and Bio-Stimulants PSB + GA₃ 400 ppm resulted best.
