Abstract

An experiment was carried out at College of Agriculture, CAU, Imphal during 2008–09 to study the Effect of nitrogen on growth, flowering and yield of tuberose (Polianthes tuberosa L.) cv. Single . The results of the study indicated that increasing nitrogen levels resulted in superior growth, flowering and yield of bulbs. Nitrogen at 220 kg/ha gave maximum number of leaves/plant, number of tillers/plant, plant height, number of spikes/plant, spike length, rachis length, number of florets/spike, duration of flowering, number of bulbs/clump and weight of bulbs/clump and was at par with that of treatment 200 kg N/ha. Flowering was advanced by control (upto 40 kg N/ha) and delayed by higher levels (60 kg N/ha and above). Nitrogen content in the leave was increased with the increased level of nitrogen.
