Abstract
We studied the effects of nitrogen (N) fertilizer (0, 20, 30, 40 and 50 g N plant") applied at transplanting and 120 days after transplanting, on growth, development and flowering of Jasminum sambac. Number of leaves per plant, leaf area and plant height were maximum with 30 g N plant" whereas leaf N content and number and fresh weight of flowers plant" were maximum with 20 g N plant". Moreover, number of leaves, leaf area, number and fresh weight of flowers were maximum in June whereas leaf N content was more in April than May and June. Nitrogen application @ 20 g plant" in June produced maximum flower yield whereas vegetative growth was enhanced upto 30 g N application plant", Keywords: Nitrogen efficiency, Jasminum sambac, leaf N %age, growth.
