An experiment was laid out during two consecutive years in Horticulture garden of C. S. Azad University of Agri. and Tech., Kanpur. There were three nitrogen sources viz. Urea, Ammonium Sulphate, Calcium Ammonium Nitrate; four levels of each of nitrogen (0, 50, 100 and 150 kg/ha) and phosphorus (0, 100, 200 and 300 kg/ha), with a total of forty treatments. The results showed that there were no significant differences observed due to nitrogen sources in respect of sprouting of bulbs. Increasing doses of phosphorus caused relatively early sprouting during both the years of study. Phosphorus applied @ 200 kg/ha expressed tallest plant during both the years of study. Number of leaves per plant improved under ammonium sulphate followed by calcium ammonium nitrate. Phosphorus @ 200 kg/ha produced maximum number of leaves during both years. Application of 150 kg N/ha or 200 kg phosphorus expressed highest leaf area followed by 100 kg N/ha.
