Influence of irrigation with domestic wastewater on different agronomical features in summer savory ( Satureja hortensis L.)

摘要

The main objective of the present study was to evaluate the effects of irrigation with domestic wastewater on different agronomical features of summer savory ( Satureja hortensis L.). In this experiment, the soil has been used as a biological filter to absorb pollution in the domestic wastewater . 15 lysimeters were used in this work that 1 to 5 lysimeters were irrigated by domestic wastewater and primary drainage water were accumulated. The 6 to 9 lysimeters were irrigated by primary drainage water and then secondary drainage water were accumulated and also 10, 11 and 12 lysimeters were irrigated by secondary drainage water . In order to compare plants characteristics the lysimeters 13 to 15 were irrigated by agronomical water. The results showed that essential oil yield of summer savory significantly increased (14%) under irrigation by secondary d rainage water into irrigation by agronomical water. The findings may give applicable advice to commercial farmers and medicinal and also aromatic plants researches for management and concern on water strategy and estimate of irrigation carefully for increa se of quantity and quality yields in medicinal and aromatic plants farming.
