Abstract
Two factors, planting date and different irrigation regimes, play a fundamental role during the growth period for optimal performance of medicinal plants. In this study, the experiment was conducted in split-plot in a randomized complete block design with three replications with different irrigation regimes (rainy, supplementary irrigation, complete) and different planting dates (spring, waiting, autumn planting) at Urmia University. The results of the study showed that different irrigation treatments and different planting dates had significant effects on canopy diameter and leaf area index; on the other hand, the interaction of planting date and irrigation time caused a significant change in the mentioned traits. The amount of proline and carbohydrate in the plant was significantly affected by the simple effects of irrigation regime and planting date; And the interaction between these two factors was statistically significant, so that in dryland and spring cultivation conditions (13.93 μmol/g) proline content showed a significant increase compared to other treatments, and the amount of soluble carbohydrates in dryland and spring cultivation conditions (13.19 μmol/g) was significantly higher than supplementary irrigation (17.85 μmol/g) and full irrigation (17.10 μmol/g). The effect of planting date on the absorption status of all elements was insignificant, while the irrigation regime had a significant effect on phosphorus absorption, so that it was the highest (72.5%) in full irrigation and the lowest (43.1%) in dryland.
