摘要：Two field experiments were carried out at the Experimental Farm of Faculty of Agriculture, Cairo University during two successive seasons 2009 and 2010, to study the effect of foliar amino acids application (tryptophan, tyrosine and glutamic) at different doses (0, 50, 100 and 150 ppm) on growth and yield parameters as well as chemical composition of Urtica pilulifera plants. The results sho wed that application of all amino acids forms significantly increased the determined parameters (plant height, number of branches, fresh and dry weight of herb , and yield of seeds) as well as chemical composition(total carbohydrate, total lipid content and total caffeic acid derivatives) in herb and seeds of plant as compared to untreated plants.The most effective treatment was application of tryptophan at 100ppm dose.
