This work is part of the research program supporting the '' Arganier Project ''. It is coordinated by the Agrotechnologies Association of Souss Massa Draa (Agrotech) in partnership with a consortium of researchers on the argan tree. The purpose of this work is to determine the favorable doses and frequencies of irrigation for a better recovery of argan plants after transplantation on three sites belonging to different agroclimatic zones; Taksbite on an ocean climate plateau, Anzad on a mountain foothill with continental climate and Tinzert with geography and mountain climate. The results of this work showed that the dose of 16 L / plant and the frequency of one month are recommended on the Taksbite site. However, on the Anzad site, these results demonstrated that the dose of 36 L / plant and both frequencies; 1 and 2 months are recommended. Similarly, the dose of 35 L / plant and the frequency of 2 months were more efficient at the Tinzert site. Finally, this experiment revealed the existence of a great heterogeneity within this population mainly due to its great genetic diversity and its adaptation with the agroclimatic conditions of each plantation site
