Oil seed crops are highly valuable in agriculture for oil extraction. Iran is among oil or oil seeds importer and therefore it is needed to imrove oil content and quality of oil seed crops. The other strategy is to introduce new oil seed crops which have high adaptability to Iran climatic condition. Nuruozak (Salvia leriifolia Benth ) is a perennial herbaceous plant that grows exclusively in south and tropical regions of Khorasan and Semnan provinces, Iran . In this study, one population collected from south Khorasan province was evaluated for variation and adaptability, seed yield, essential oil, and some morphological traits in 3 different planting dates of late March, mid April and late April in Isfahan. Measured morphological traits were leaf area, number of leaf per plant, spread diameter, and plant height. The number of self-pollinated and open-pollinated seeds and leaf essential oil content and phenolic compounds were measured on all plants in the plots. Seed oil was also extracted and oil fatty acid profile wa determined using GC analysis for three planting dates. The results of analysis of variance showed that the eefect of planting date was significant on the number of flowering branches, height of flowering branch, the length of inflorescence, number of leaves and plant canopy diameter. However, planting date was not effective on chlorophyll a and b content and carotenoids concentrations. The seeds had about 28% oil containing more than 70% of oleic and linoleic acids which may indidicate the possibility to use it as sedible oil. The number of seeds produced via self pollination was lower than cross pollination. This may show that this species is a croos pollinated one although it is not obligative and a few percent of self pollination was observed. It seems that mid April is sutable for sowing Nuruozak seeds in Isfahan. Keywords: Nuruozak, Essential Oil, Oil, Phenolic Compounds
