Climatic factors influences the production of active principles of aromatic plants. We evaluated the biomass and essential oil of basil (Ocimum basilicum L.). Basil growns mainly by small farmers seeking to sell their leaves, which can be used fresh, dried, as flavorings or seasonings. The experimental design was completely randomized in a 2x2x2 factorial (growing seasons, environments and different kinds of fertilizers). We analyzed plant height, length and width of leaves, fresh and dry weight, yield and essential oil. Comparing the season and environments, the results showed that the plant height were higher in second season. The fertilization did not significantly influence the development and production of essential oils of basil at the two cropping seasons. The cultivation in winter in a protected environment favored crop development, production and essential oil yield.

RÉSUMÉ
Sweet basil (Ocimum basilicum) is an annual herb plant belonging to the Lamiaceae family that is used as a drug, spice and fresh vegetable. In order to study the effects of different levels of water stress on some element of the plant, O. basilicum was subjected to deficit irrigation using four treatments viz. control, irrigated with 70% of soil water capacity (SWC), Treatment 1, irrigated with 50% SWC, Treatment 2, irrigated with 30% SWC and Treatment 3, irrigated with 10 % SWC. Plants were divided into four growth stages, Viz., vegetative (35 days after sowing, DAS), pre-flowering (49 DAS), flowering (63 DAS) and seed setting (77 DAS). Essential elements of leaves were investigated under these irrigation treatments at each growth stages. The results at the end of each growth stage indicated that there is no significant reduction in essential elements quantities compared to that of full irrigation control. The quantities remained high even in the lowest irrigation plants (T3, 10% SWC). The lowest irrigation plants accumulated, high nitrogen (N) Calcium (Ca) , magnesium (Mg), potassium (K) and phosphor (P), compared to control plants. Moreover, low irrigation helped Ocimum plants to accumulate less chloride than the full irrigated control. These results may be attributed to the ability of this plant to acclimate to water shortage.
