Online published on 13 January, 2016. Abstract An investigation was carried out at the Horticultural Research Farm, Mondouri, Bidhan Chandra Krishi Viswavidyalaya during March 2011 to March 2012, to find out the impact of plant densities on production of cut spike in tuberose (Polianthes tuberosa L.) cv. Prajwal. Tuberose bulbs of medium (2.5–3 cm) sized were planted in nine different spacing viz. 10x15cm, 30x30cm, 15x30cm, 30x20cm, 20x20cm, 30x45cm, 20x45cm, 45x45cm and 45x60cm as different treatments with four replications laid out in RBD (Randomised Block Design) and the results were analyzed statistically. A simple correlation study was conducted to study the relation between the plant density (number of clumps/plot) and the vegetative and flower characters. A significant negative correlation (p<0.05) was obtained between the number of clumps/plot and no. of leaves/clump, weight of spike(g), diameter of spike(cm) and no. of floret. Among the vegetative characters a significant negative correlation (p<0.05) was obtained between no. of leaves/clump and leaf length(cm). Among the flower characters, weight of spike(g) was found to be positively significantly correlated (p<0.05) with diameter of spike(cm), rachis length(cm), no. of floret, and weight often florets(g) where as number of spike/plot was positively significantly correlated (p<0.05) with all the other flower characters. A significant positive correlation (p<0.05) was obtained between diameter of spike(cm) and rachis length(cm), no. of floret and weight of ten florets(g). Also rachis length(cm) and weight often florets(g) were found to be positively significantly correlated (p<0.05).
