A field experiment was carried out to investigate the effect of bio-fertilizers and organic manures on plant growth, flowering and tubers production in dahlia (Dahlia variabilis L.)  cv. S.P. Kamala, during November 2012 to March 2013 at Floriculture Research Field,  Department of Horticulture, Sam Higginbottom Institute of Agriculture Technology and Sciences, Allahabad (U.P.). Different levels and combination of bio fertilizers and organic manures was applied to assess the vegetative, floral and yield characteristics of dahlia. The experiment was laid out in randomised block design with ten treatments and three replications. The maximum plant height (65.07 cm), number of primary branches (9.67), number of leaves (33.67), plant spread (43.73 cm), number of flowers (8.13), duration of flowering (10.53), flower yield ha-1 (33.65), weight of tuber (56.67 g), number of tubers (4.87) and tuber yield (13.80 t ha-1) were produced in the treatment (T8) Vermicompost @ 2.5 t ha-1 + Azotobacter @ 2.0 kg ha-1 + Phosphorous Solubilizing Bacteria @ 2.0 kg ha-1.

Key words: Azospirillum, Azotobacter, Farmyard manure, PSB and Vermicompost
