Balango (Lallemantia iberica Fischer & C.A. Meyer) belongs to the Lamiaceae family. Considering its medicinal and industrial properties and its role in agriculture, this plant is considered a multipurpose plant. The oil of this plant is used in tanning, leather making, dyeing, lubricant, as a substance to prevent wood decay, furniture wax, printer ink, soap preparation, and in lighting linoleum factories, polishing oil, painting oil and grease oil (Shahbazi et al., 2012). Medicinally, balango seeds have mucilage, which is known as an expectorant, diuretic and anti-abdominal medicine (Asghari et al., 2017). This experiment was conducted based on a randomized complete block design in a farm located in Miandoab city. The treatments included complete irrigation (S1), withholding of irrigation from the beginning of flowering to the end of ripening (S2) and withholding of irrigation from the beginning of branching to physiological ripening (S3). The results of comparing means show that dehydration, especially the withholding of irrigation from the beginning of branching to physiological ripening, had a significant decrease in essential oil yield and anthocyanin content, and in terms of phenolic compounds and soluble sugars, there was no significant difference between treatments S1 and S2, and the lowest value was related to treatment S3. In terms of proline, the highest amount was related to the treatment of S3 solution, these results were in agreement with the effect of stress on lemongrass plants (Kazemi Nasab et al., 2015).
