An investigation was conducted under the full sun at the nursery of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to examine the effect of blending irrigation water with primary treated sanitary water at the levels of 0, 25, 50, 75 and 100 °(o, alone or in the presence of the effective microorganisms (EM) biostimulant, which added with irrigation water at the rate of 3 ml/1 on growth and chemical composition of 10-months-old Neem (Azadirachta indica L.) seedlings cultivated in 16-cm-diameter black polyethylene bags filled with about 3.5 kg of clay and sand mixture (1:1, v/v). The obtained results indicated that means of all vegetative and root growth parameters were significantly increased as a result of irrigation with sanitary water up to 75 % level where the level of 50% sanitary water treatment gave the highest means compared to those of the control and other levels of sanitary water in the two seasons. A pure sanitary water (100 % level) slightly reduced means of various growth traits to become less than those of control with non-significant differences among them in most instances of both seasons.
