We studied the effects of nitrogen (N) fertilizer (0, 20, 30, 40 and 50 g Nplant-1) applied at transplanting and 120 days after transplanting, on growth,development and flowering of Jasminum sambac. Number of leaves per plant, leafarea and plant height were maximum with 30 g N plant-1 whereas leaf N contentand number and fresh weight of flowers plant-1 were maximum with 20 g N plant-1. Moreover, number of leaves, leaf area, number and fresh weight of flowerswere maximum in June whereas leaf N content was more in April than May andJune. Nitrogen application at the rate of 20 g plant-1 in June produced maximumflower yield whereas vegetative growth was enhanced up to 30 g N applicationplant-1.
