The present investigation was carried out to study the effect of organic manures and biofertilizers on growth, flowering and post harvest attributes of tuberose var. Shringar during 2010-2012. The experiment was conducted in Randomized Block Design (RBD) with four replications. The maximum 2 plant height, number of leaves/plant, rachis length and yield of spikes/m was obtained with the use of 2 kg vermicompost/m2 whereas application of 2 0.5 kg poultry manure/m2 in tuberose registered the maximum spike weight, number of florets/plant and minimum number of unopened florets/plant. 2 This treatment also found best for maximising the weight and diameter of mother bulb and number of bulblets/m2 . Spikes which were harvested from 2 the plot and treated with Pseudomonas sp. (40 g/m ) resulted in maximum vase life and also in weight of bulblets and number of bulblets/plant.
