Satureja sahendica Bormn., which is native to Iran, is a medicinal species from Lamiaceae family and its habitat is west of Iran. In a split plot experiment, the effects of nitrogen fertilizer at levels of 0 (control), 40 and 80 kg/ ha (as main plots), and the sowing density of 8, 10 and 12 plants /m2 (as sub plots) were studied on height, number of branches per plant, yield and the essential oil yield of aerial parts of S. sahendica. The experiment was carried out in agricultural research farm of Takestan, Islamic Azad University of Iran, during 2009-2011.There was no significant difference in terms of height, number of branches per plant, the yield of flowering shoots and oil content between using 40 and 80 kg/ha nitrogen treatments. However, higher values were recorded for both treatments compared to control. The highest essential oil content and oil yield was obtained by application of 40 kg nitrogen per hectare and using more nitrogen reduced the oil yield. A sowing density of 10 plants per square meter increased aerial part yield and oil yield. The highest yield of flowering shoot, and essential oil yield were obtained by application of 40 kg nitrogen/ha and a sowing density of 12/m2 (2096 kg/ha, 2.1 percent and 44.1 kg /ha, respectively) that showed no significant differences by application of 40 kg nitrogen per hectare and the sowing density of 10 plants /m2.

Thymus daenensis Celak. is distributed in some areas of Iran such as Qazvin province. In order to evaluate essential oil yield and composition of T. daenensis an experiment was conducted in research farm of Qazvin Research Station based on randomized complete block design with three replications during 2006-2008. Aerial parts of the plants were dried in shadow and hydro distilled for obtaining their essential oils. Capillary GC and GC/MS analysis were used to determine the volatile profile of the essential oil samples. Fresh and dry herbage yields of T. daenensis were 9124-1568, 10250-2176 and 11337-2750 kg/ha in 2006, 2007 and 2008 respectively. Aerial parts yield were higher in the first cutting and showed decreased trend in latter cutting each year. The yields of fresh and dry biomass were 3498-800 kg/ha for the first cutting, 3015-720 kg/ha for the second cutting, 1947-508 kg/ha for the third cutting and 1976-504 kg/ha for the forth cutting. There was no difference in volatile oil percentage in different years, but there were significant difference between different cuttings. The oil yield was 2.83% at third cutting and 3.07% at first cutting. Thymol, γ-terpinene, ρ-cemene, metyl-eyther carvacrol and carvacrol were the main components of essential oil in all cuttings and years. Thymol percentage was varied from 69% (first cutting) to 76% (second cutting) in the essential oils of T. daenensis.

Satureja sahendica Bornm.is an endemic aromatic species in Iran. It isused very extensively in folk medicine of southern parts ofIran. In this study, chemicalcomposition of cultivated S. sahendica was investigated for the first time. Three accessions of S. sahendica collected from natural sites in Qazvin province and cultivated in research farm of Qazvin Research Station in 2005. An experiment was undertaken to determine the oil production of S. sahendica in complete randomized block design with three replications. Accessions consisted of Arochan, Abgarm and Shenein. Aerial parts of wild and cultivated plants harvested at flowering stage in 2007. Essential oils of dried aerial parts were distilled with water for 3 hours. Statistical analysis showed significant difference between cultivated and wild plants of accessions. In natural site, Shenien had the highest essential oil content (3.3%) and then Abgarm (3.0%) and Arochan with 2.21% was the least. In cultivated plants accessions had not similar trend in different harvests. Abgarm samples at first and second cuttings and Arochan samples in third cutting showed the highest essential oil contents. There was high difference between cultivated and wild accessions of Shenien. Thymol was 35 to 36% at cultivated and wild samples, while among cultivated plants, Abgarm sample in third cutting showed the highest amount of thymol (49.6%). Second cutting of Arochan sample and first harvest of Shenien sample had 38.8 and 38.1 % thymol respectively. Carvacrol in wild plants was nearly 1% and was higher than cultivated plants.

In order to study the effect of nitrogen levels and plant density on seed yield, essential oil and oil content of Coriander seeds, an experiment was conducted in agricultural station of Qazvin and natural resources research center in 2005. The experiment was laid out by adopting split plot design with four replications, main plots were nitrogen: 30, 60 and 90 kg/ha and subplots were plant density including: 20, 30, 40 and 50 plant/m2. Seed yield, essential oil, oil content and yield were determined. Results showed nitrogen and plant density effected on Seed yield, essential oil, fatty acids. With increasing of nitrogen to 60 kg/ha, there was a significant increase in seed yield. The seed yield was decreased with more nitrogen. But the highest essential oil content and fatty acids were obtained with 90 kg nitrogen /ha. With increasing of plant density, seed yield and oil content had a significant decrease. Seed yield and oil content were higher in 30 plant/m2, while essential oil was higher in 40 plant/m2 that there was no difference with 30 plant/m2 in this respect. Comparing of treatments showed that the highest seed yield and essential oil yield were obtained by using 60 kg nitrogen/ha while there was the highest essential oil content, content and yield of oil with the application of 90kg nitrogen/ha with 30 plant/m2.

In order to study the autumn and spring cultivation of Fennel (Foeniculum vulgare), Ajowan (Carum copticum), Black cumin (Nigella sativa) and Anis (Pimpenella anisum) under irrigation and non-irrigation conditions an experimental bulk design with 4 replications was conducted in Alamut medicinal plant research station in 2000 and 2001. Each medicinal plant was studied in a separate experiment. Treatments were included: autumn + irrigation, autumn + non–irrigation, spring + irrigation and spring + non-irrigation. The results showed significant different responses mentioned plants planting season Fennel and black cumin had earlier spring growth, more shoot, seed weight, and more seed yield because of better establishment in autumn. While ajowan and anis autumn planting could not be successful because of damping off, so their planting can only be practical in spring. All plants were better in respect of height; seed weight and seed yield in irrigation compared with non-irrigation condition. There was less difference between seed yield of fennel in irrigation and non-irrigation condition in autumn planting. Fennel and black cumin had 1703 and 1298 in irrigation, 948 and 447 kg/ha in non-irrigation condition in autumn planting. Also ajowan and anis had 1147, 1120 in irrigation and 312 and 361 kg/ha in non-irrigation condition in spring planting. Result of Pearson Correlation Coefficient about black cumin showed that there were significant correlations among all of the traits.

The effects of irrigation regimes on yield and agronomic characteristics of black cumin (Nigella sativa) were studied at the medicinal plants Research station of Qazvin Agricultural and natuoral resources research center during the years 1997 and 1998. A compele randomized block design(CRBD)with three replications was used. The treatments comprised four irrigation periods, 7, 14 , 21 interval days and without irrigation.The characteristits studied include of plant height, 1000 grains weight, number of capsule per plant, number of seeds per capsule, seed/capsule weight ratio and seed yield. Results showed that irrigation perriods in each of two years significantly affected effects plant height, number of capsule per plant, number of seed per plant and seed yield. The seven- day irrigation interval had the highest seed yield (1118kgha-1). There was no difference between treatments in respect of 1000 grains weight and grain/capsule weight ratio. However in water deficit and non- irrigation condition, plant showed resistance to the drought and produced crop with minimum soil moisture of the measured parameters, there was a significant correlation between yield, plant height, number of capsule per plant and number of seed per capsule.

This experiment was conducted on 2001 and 2002 in reseach farm of Qazvin Agriculture Research Station, in order to study the effect of different rates of nitrogen, Phosphorus (Conventional system), manure (Organic system) and mixture of them (Integrated system) on seed yield and essential oil content of Ajowan (Carum copticum). The experimental design was used randomized complete blocks with three replication. Treatments included: different rates of N and P (as mixture) with 4 levels, different rates of manure with 3 lebvels, mixture of N, P and distillation method. The results showed that increase in N and P fertilizer up to 90 and 60 kg/ha respectively, was followed by seed yield increase but fertilizers had no effect on the essential oil content. Also, seed yield essential oil content increased as a result of increase in manure application. In general integrated treatments in respect of seed yeild and essential oil yield were higher than other treatments.
