To encourage vegetation propagation of Atriplex nummularia, Lindl. two greenhouse experiments were conducted at Agronomy Department of Faculty of Agric., Mansoura Univ., Egypt throughout November and December, 2013 in Factorial experimental design in randomized complete blocks in four replications. The first experiment including nine treatments were the combinations between three types of stem cut, Woody cut, Semi woody cut and Fresh cut as well as three types of cuts from position on main stem i.e. Terminal, Intermediate and Basic. The second experiment including twenty treatments were the combination between four types of rooting media i.e. Clay, Sand, Beat Moss and Water and five mechanical and chemical treatments i.e. the control, seed scarification, treating cuts with plant growth regulators such ABA (10 ppm), NAA (10 ppm) and IAA (10 ppm) for 24h. It could be summarized that using semi woody cut and using a basic cuts or intermediate cuts significantly recorded highest number of formed roots, number of new leaves/plant and root volume in cm3/plant. In addition, using sand rotting media and treating cuts with ABA at rate of 10 ppm or NAA at rate of 10 ppm for 24h increased number of new leaves/plant and number of branches/plant.
