The objective of this work is to study the effect of three substrates and type of cutting as well as the chemical treatment and the microclimate on the success of cuttings from the Argan tree (Argania spinosa.L). The results obtained showed that, depending on the type of substrate, a survival rate of 58.33%, 33.33% and 42.33% respectively for substrate 1 (soil only), substrate 2 (1/2 sand and 1/2 compost) and substrate 3 (1/3 soil + 1/3 compost + 1/3 peat). Regarding the type of cutting, high rates were prevalent in the apical cuttings. For the substrate effect, we obtained a survival rate of 58.33%, 33.33% and 42.33% respectively for substrate 1, substrate 2 and substrate 3. Considering the type of treatment, the development of the buds took 33 days, 37 days and 41 days, respectively for product 1 (Auxin), product 2 (mineral-based) and product 3 (Seaweed extract). As a result, the increase in temperature and humidity, reduced the budburst time by up to two weeks, with the formation of new shoots numbering 4 to 5 per cutting and 15 to 20 new leaves. In our study, we encountered rooting problems, which led us the shoots acquired in the herbaceous grafting technique.
