The aim of this study was to investigate the effects of various fertilizer treatments on the morphological traits and mineral content of Aloe vera plants. The experiment was conducted in a greenhouse in Rabat, as well as two other fields in Skhirat and Sidi Bettach. The treatments including the ‘no application’, control F0 and three treatments which is compost (Organova) F1, compost combined with humus (Humivital) F2, and nitrogen (ammonitrate) 33% F3. The productivity of biomass was estimated based on the variables of morphological traits and mineral content. The effect of organic and inorganic fertilizers on the different variables of Aloe vera depends on the site. Significant effects were found for the most of the variables such as length, width, dry matter; ash content, manganese Mn, copper Cu, zinc Zn, calcium Ca, potassium K, carbon C, nitrogen N, sulfur S contents. Site effect was significant, with the higher values obtained for length, Width, Dry matter, Ash contents, Ca and N in Skhirat. Site effect was also significant for Mn and Cu in Sidi Bettach, and K in the greenhouse. The effect of the treatment F1 was significantly higher for the length and width of the leaves than F3 and the control F0, in addition F2 was significantly higher for the width of the leaves, nitrogen N and sulfur S contents.
