A pot experiment was conducted in the two successive seasons 2004/2005 and 2005/2006 at the Experimental Nursery of the Ornamental Horticulture Department, Faculty of Agriculture, Cairo University, Giza, Egypt., with the aim of investigating the tolerance of sisal plant (Agave sisalana) to different levels of irrigation water salinity (0, 1000, 2000, 3000, 4000, 5000, 6000 and 7000 ppm) as NaCl & CaC12 (1:1 by weight). In addition the effect of different fertilization treatments [unfertilized (control), organic fertilization (50 g compost / pot), chemical fertilizer (NPK) (2 g / pot), and compost plus NPK fertilizer], on reducing the unfavorable effects of salinity on vegetative growth and anatomical structure. The recorded results indicated that increasing salinity levels decreased most of the studied parameters (plant height, number of leaves /plant, leaf area, leaf thickness, and dry weights of foliage and fibrous roots /plant). The anatomical study supported and explained the recorded reduction of morphological traits under investigation due to salinity treatments. In general, it was noted that raising the level of salinity of irrigation water caused gradual decreases in means of all the studied characteristics in both seasons, and these decreases were remarkable at a salinity level of 7000 ppm. On the other hand, the fertilization treatments reduced, to some extent, the negative effect of salinity.
