Bulb Size Effects on Flowering and Bulb Production of Tuberose (Polianthes tuberosa L.) cv. Single
Asian Journal of Agricultural and Horticultural Research, Volume 9, Issue 4,
A field experiment was executed under sub-tropical conditions during the period from April 2020 to March 2021 to observe the effects of bulb sizes on the flower and bulb yield of tuberose cv. single. The experiment consisted of three bulb sizes namely, a small-sized bulb (1.0-1.5 cm in diameter); a medium-sized bulb (1.6-2.5 cm in diameter) and large sized bulb (2.6-3.0 cm in diameter). Results disclosed that plant height, the number of leaves plant-1, leaf length and breadth, the number of lateral shoots plant-1, production of bulbs plant-1, bulb length and diameter, bulb yield both plant-1 and hectare-1, length of rachis, spike length and diameter, the number of florets spike-1 and flower yield both spike-1 and hectare-1 were increased with the increment of bulb sizes. The longest plant, highest leaf production, larger leaf, bulb production plant-1, bulb size and bulb yield both plant-1 and hectare-1, rachis length, spike length and diameter, number of flowers spike-1, flower yield both spike-1 and hectare-1 were recorded in large sized mother bulb. In contrast, the lowest above the studied parameters were obtained in small-sized mother bulbs. So, large-sized bulbs can be used for commercial production of flowers and bulb of single cv. of tuberose.
- bulb size
- flower longevity
- flower yield
