The current study was performed to evaluate the effect of planting date and locality of seed on seed yield of Pimpinella affinis Ledeb. The experiment design was factorial done using a randomized complete blocks design with three replications. Treatments included locations from where seeds were collected (Khojir, Noshahr and Chalous Road areas) and planting dates (November 6th, December 6th and April 9th in 2006 and 2007). The experiment was performed in Alborz farm research complex located in Karaj. The results of variance analysis of the experiment in 2006 showed that the effect of planting date on seed yield was not significant while the effect of locality and interaction effect between planting date and locality was statistically significant at 1% significance level. Means comparison of treatments showed no significant differences between the yield seed of planting dates of November 6th and December 6th, while December cultivation's yield seed was higher (64.467 Kg/ha). The effect of locality on yield seed was significant as yield seed of Khojir locality (175.1 Kg/ha) was more than that of Chalous and Noshahr localities. Interaction effects between locality and planting date on yield seed were statistically significant at 5% significance level. Yield seed of December cultivation from Khojir locality (191.4 Kg/ha) was the highest amount. The results of variation analysis in 2007 showed that the effects of planting date, locality and their interaction on seed yield were significant at 1% significance level. Means comparison of treatments showed no significant differences between the yield seed of planting dates of November 6th and December 6th, but they had significant difference with April cultivation, while November cultivation's yield seed was higher (218.9 Kg/ha). The effect of locality on yield seed was significant as yield seed of Khojir locality (281.9 Kg/ha) was more than that of Noshahr locality. Interaction effects between locality and planting date on yield seed were significant as yield seed of November and December cultivations from Khojir locality (404.6 and 397.9 Kg/ha) was the highest amount. According to the results of cultivation for two years it can be concluded that autumn cultivation had more yield seed and biological function than that of spring cultivation due to having long growth period. In addition, seeds collected from Khojir locality had the highest yield seed and biological function among three studied localities.

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.

The extensive waste dry lands of Iran, shows necessity of selection and cultivation of tolerant and suite plants for more production, cover green and erosion inhibition under dry farming system. Effects of plant density on seed yield and yield components of Foeniculum vulgare Mill. Had been studied under Damavand dry farming in 2003-2007. This experiment was conducted under RCBD with using 3 plants densities and 4 replications. The results showed significant differences among the densities treatments in dry matter, seed yield, plant height, seed weight per plant and 1000 kernel weight in the third year. The Fennel yield's of dry matter in the first, second and third year of experiment were 1229, 779 and 2079 kg ha-1 and seed yield reached to 611, 280 and 712 kg ha-1, respectively. Finally Foeniculum vulgare could be considered as a tolerant and adaptable medicinal plant under dry land of Damavand and similar cold regions.
