Abstract: Response of Zinnia elegans Cv. Meteor to different levels of nitrogen was studied during the year 2002. Vegetative characteristics viz., plant growth rate per week, plant height, number of laterals, length of laterals, number of leaves and leaf area, were positively affected by increasing the dose of nitrogen (from 5 to 20 g pot-1). Emergence of first flower delayed while number of flowers per plant, size of flowers and blooming period generally decreased at higher level of nitrogen. Nitrogen application @ 20 and 10 g pot-1 were most effective in improving the vegetative and floral characteristics, respectively.
