its age in comparison with the other two young orchards. This high nitrogen requirement, combined with initial low nitrogen content in the soil (**Table 7**) could explain this response of the olive tree to nitrogen at S2. The low yield at S2 could also be the result of a lack of water during the period before flowering and which negatively affected the latter. The 0.5 Kg N.tree−1.year−1 dose allowed the best yield (57.7 Kg.tree−1). This result found at S2 is in agreement with that reported by Garcia [11] who recommended 0.5 to 1 Kg N.tree−1 based mainly on the nitrogen exports of the olive tree.
