Abstract:

An experiment was conducted 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. 10x15 cm, 30x30 cm, 15x30 cm, 30x20 cm, 20x20 cm, 30x45 cm, 20x45 cm, 45x45 cm and 45x60 cm as different treatments with four replications laid out in RBD (Randomised Block Design) and the results were analyzed statistically. Significant difference in treatment effects were found in case of number of leaf, number of floret, spike diameter, spike weight, yield, blooming period (field life) and chlorophyll content. Among all the treatment maximum plant height (80.03cm) and higher leaf length (63.76 cm) were observed with the spacing 2020 cm whereas the treatment 4560 cm showed the highest leaf number (45.06). The highest leaf area and leaf length were recorded with 10x15 cm. The spacing of 3030 cm recorded optimum plant height, number of leaves, leaf breadth, leaf area, number of spike/plot, spike length, spike diameter, number of florets/spike and weight of ten florets. The maximum blooming period and vase life were observed with the spacing 4545 cm and 4560 cm. From these results it can be concluded that tuberose cv. Prajwal may be planted at spacing of 3030 cm was considered to be better treatment among all for quality cut flower productio
