Abstract
Background and objectives: Valuable and adapted medicinal plants for using in dry farming could creates green cover in all dry seasons, prevent soil erosion in slopies and increases the rainfall productivity in vast drylands of Iran. Four species of medicinal plants of the genus Satureja, with the scientific names Satureja bachtiarica, S. mutica, S. spicigera and S. sahendica, belonging to the mint family, are perennial, valuable, adaptable and exclusive to Iran and were used in this project under rainfed conditions.
Methodology: Due to prove this hypothesis, four separate experiments were conducted in dryland regions of vicinity of Tehran(Research Station of Damavand) dependent of Research Institute of Forests and Rangelands(RIFR) , during 2016- 2021. In these experiments four Satureja species (S. mutica, S. spicigera, S. sahendica and S. bachtiarica) were used as the valuable, adapted and exclusive medicinal plants under dry farming system. The field experiments were carried out in a split plot design with 3 nutrition treatments including; 30-ton manure, 10-ton straw enriched with Ammonium Sulphate and control as the main plots, also 3 plants densities treatments including 26666, 40000 and 80000 Plant/ha as the sub plots. The measurments adjective were; plant height, canopy diameter, main stems, dry matter yield, dry / fresh yield relation, essential oil percent and yield’s.
Results:The results of traits in the experiment’s years shows an increasingly trend which shows growth and tolerance of Satureja species under dry farming of Damavand region. The highest dry matter yield were observed with 1821 Kg/ha and essential oil with 2.86 % by S. mutica as the valuable and chosen species in the third year. In this experiments which compared four Satueja spp, the morphological and yield were high in the control and manure application in high density treatments for S. sahendica & S. bachtiarica with limited canopy and for S. mutica & S. spicigara with medium density.
Conclusion:The highest rates in more traits in the control indicated fertilization restriction and health of savory which produced under dry land farming. Successfully in cultivation, establishment and growth of Satureja species in dryland farming denoted the adaptability and economic yield of Satureja species under the dry farming in cold semi stepic regions with 300-400 mm annual rainfall of the Iran.Conclusion:The highest rates in more traits in the control indicated fertilization restriction and health of savory which produced under dry land farming.
