Abstract—Nano-fertilizers can be substituted for conventional fertilizers. Cycocel (CCC) is one of the most important growth retardants which inhibits gibberellin. Euphorbia pulcherrima. Treatments were Fe chelated fertilizer (0, 0.9, 1.8, 3.6 and 4.5 g l^-1) and cycocel (0, 500, 1000, 1500 and 3000 mg l^-1) on Euphorbia pulcherrima. The least plant height and the most shoot, leaf number, root length, root volume, the number and permanent of color bracts were obtained in treatments of 1.8 g l^-1 iron Nano-fertilizer without or with the concentration of 1000 mg l^-1 cycocel. The most leaf surface was calculated in plants treated with 1.8 g l^-1 iron Nano-fertilizer without cycocel. The minimum amount of root volume and chlorophyll content was seen in the maximum of iron Nano-fertilizer and cycocel concentrations. Suitable root characters were severely reduced under the effect of 3000 mg l-1 cycocel. In overall, the most suitable treatment, especially for reduction of plant height and enhancing some vegetative traits and flowering is introduced in treatment of 1.8 g l^-1 iron Nano-fertilizer along with 1000 mg l^-1 cycocel.
