Two different trials were executed at the Experimental farm, faculty of Agriculture, Minia University during the two successive seasons 1990/1991 and 1991/1992. The first experiment was conducted in pots and was arranged as a split-plot experiment. It was dealing with the effect of soil type, clay loamy versus sandy calcarious in the main plots and different N,P and/or K single and combined fertilization treatments, as well as, X-Garden (including Mn, Fe and Zn) at 0.5 or 1.0, alone or combined with the NPK treatments in the sub-plots on growth, flowering, bulb production and chemical composition of iris plant, wedgewood.The second experiment, however, was conducted in the field as a split plot experiment also.It was performed in order to investigate the effect of three bulb sizes, Large, Medium and Small in the main plots and three growth regulators, gibberellic acid at 50.100 or 150 ppm alar at 500.1000 or 1500 ppm or mepiquate-chloride
