Studies on the effect of nitrogen on growth and colchicines content in glory lily were carried out in hydroponic greenhouse, Department of Horticulture, Faculty of Agriculture, Chiang Mai University during May, 2001-2002. The experiment was focused on the effect of nitrogen solution supplemented with different levels of nitrogen i.e., 0, 210 (control), 420 and 630 mgN/l. It was found that nitrogen concentration at 210 mg/l was optimal for glory lily cultivation which resulted in significantly better plant height and tuber fresh weight. This treatment yielded higher numbers of flowers and pods. Colchicine in 420 mgN/l treatment was the highest at 90.469 mg/plant at flowering stage. Glory lily 210 mgN/l treatment contained the highest colchicines content at 29 DAP.
