Combined effect of nitrogen and spacing on tuberose (Polianthes tuberosa L.) c.v. double

A field experiment was conducted on Tuberose to find out the combined effect of Nitrogen and plant spacing to get the maximum growth, flower and bulb production of Tuberose. The results revealed that combined effect of different level of Nitrogen and plant spacing significantly influenced the growth and yield parameters of Tuberose. Findings shows that, application of highest dose of Nitrogen with medium spacing N3S2 induced early spourting and significantly increased maximum growth and flower parameters and weight of bulb. Maximum number of bulb were recorded with maximum dose of Nitrogen with close spacing N2S1, while number of bulb lets reported maximum with N1 S1.
