Effect of Organic Manures and Biofertilizers on Vegetative, Floral and Post Harvest Attributes in Tuberose (Polianthes tuberosa) var. Shringar

Abstract

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.
