  To evaluate theeffect of different ratios of animal manure and super absorbent polymer on some physiological characteristics of fennel under drought stress conditions, an experiment was conducted as spilt-plot based on a randomized complete block design with three replications in 2015 at the University of Shahrekord. Different levels of drought stress consisted of three levels of: control (50 mm), 100 mm and 150 mm evaporation from class A pan assigned to the main factor and different ratios of animal manure and super absorbent polymer in six levels including: D1: lack of manure and super absorbent polymer, D2: 10 t.ha-1 manure + 150 kg.ha-1 super absorbent polymer, D3: 20 t.ha-1 manure + 100 kg.ha-1 super absorbent polymer, D4: 30 t.ha-1 manure + 50 kg.ha-1super absorbent polymer, D5: 40 t.ha-1 manure and D6: 200 kg.ha-1 super absorbent polymer to the sub-factor. The results showed that the drought stress and animal manure and super absorbent polymer and their interactions had a significant effect on proline, chlorophyll b, and carotenoid contents, seed and essential oil yields. Also, the highest seed yield (146.66 g.m-2), essential oil yield (2.99 g.m-2) and carotenoid were obtained from control with D6. The highest proline content was obtained from 150 mm with the use of D4. The highest chlorophyll b was obtained from control and D3. The highest relative water content and total chlorophyll were obtained from control and D6, while the highest chlorophyll a was achieved from control and D4 treatment. In general, the highest seed and essential oil yields were obtained from 50 mm evaporation and 200 kg/ha superabsorbent polymer treatments. On the other hand, the effects of drought stress on seed and essential oil yields decreased by application of 40 t/ha manure at 100 mm evaporation conditions. Also, at 150 mm evaporation and use of manure and superabsorbent polymer (30 t.ha-1 and 50 kg/ha, respectively), the effects of drought stress on seed and essential oil yields decreased as compared to the other treatments.

  One of the medicinal plants in resort areas of Mazandaran province is Phlomis olivieri which is widely used in pharmaceutical, food and cosmetics industries. This study was investigated the essential oil compounds of Phlomis olivieri aerial parts in Baladeh (Noor) and Kelardasht and also investigating the effect of soil physical and chemical properties on quantitiy and quality of essential oil. Eerial parts of plants were collected and essential oil was extracted with Clevenger device and compounds were identified with GC and GC/MS. Soil samples were randomly picked and were transfered to soil science laberatory to determine physical and chemical properties. The results showed that in Baladeh region, 27 compounds were identified which comprise 92.04 percent of total essential oil volume. At Kelardasht site, 26 compounds were identified which comprise 97.43 percent of total essential oil volume. The highest compounds in both regions were: Alpha- pinene, Beta-Caryophyllene, (E)-Beta-Farnesence, Germacrene- D, Germacrene– B and Beta-Eudesmol. Average essential oil efficiency in Baladeh and Kelardasht sites were 0.35 and 0.75, respectively which the highest essential oil amount was achieved in Kelardasht region. There was positive correlation between essential oil yield and saturation percentage and soil absorbable nitrogen, phosphorous and potassium explaining that with increasing these elements, essential oil yield was increased. Also, positive and significant correlation was observed between essential oil yield and organic carbon and matter percent at probability of 5 percent. Negative and significant correlation was found between essential oil efficiency and pH at probability of 1 percent which means that the lower essential oil with increment in this factor. Due to the Kelardasht has a higher yield of essential oil and also the percentage of essential oil compounds than Baladeh, the use of Phlomis olivieri is recommended in Kelardasht for cultivation and also for more production of these compounds.

  Drought stress is as one of the most important limited factors that in agriculture systems can cause damage to growth, yield and secondary metabolites in medicinal and aromatic plants. A filed experiment to study on effect of irrigation frequencies, including 4, 6, and 8 every days on quantity and quality of the essential oil from the aerial parts of sage (Salvia officinalis L.) was done based on a randomized complete block design (RCBD) in three replications at the research field at Islamic Azad University of Shahrekord, southwestern Iran in 2016. The leaves of sage were harvested at early flowering and the essential oil from the dried leaves was subjected to hydrodistillation using a Clevenger-type apparatus. The essential oils under different treatments were analyzed by GC and GC/MS. Results indicated that irrigation frequencies levels had significant effects on essential oil yield and percentages of 1,8-cineole (as the main constituent in the oil), limonene and α–humulene. The highest yield of the essential oil and the maximum contents of 1,8-cineole (11.05%), limonene (2.67%) and α–humulene (1.32%) were obtained from treatment of eight every days of irrigation. Probably, it seems that increased irrigation intervals (mild drought stress) can be effective in quantitative and qualitative properties of essential oil from sage (Salvia officinalis L.).

  The aim of this research was to evaluate the response of agronomic indices and quality and quantity yield of fennel to integrated application of bio-chemical phosphorus fertilizer. So, ten treatments (factorial combination of application and non-application mycorrhiza with five levels of zero, 300, 600, 900 and 1200 mg phosphorus per pot) were evaluated in a randomized complete block design (CRBD) with three replications. Effect of treatments on plant height, number of branches per plant, number of umbel per plant, number of umbelest per umbel, number of seed per umbel, number of seed per umbelest, grain yield, biological yield and percent and essential oil yield was significant. According to means comparison, the highest value of plant height (75cm), number of umbel per plant (35umbel), number of seed per umbel (325 seed), grain yield (16 gr per plant), biological yield (35 gr per plant), essential oil percent (2.71%) and essential oil yield (0.43 gr per plant) were achieved at mycorrhizal plants with application of 300 mg phosphorus. But, number of seed per umbelest with comparison to the control treatment (without application of chemical or bio fertilizer) decreased. In general, results showed that integrated application of biological and chemical phosphorus fertilizers improved quantity and quality traits of fennel and decreased consumption of chemical phosphorus fertilizer which is in agreement with the sustainable production of medicinal plants and safe environment.

  Using medicinal plants as drug or spice in food have significantly increased in recent decades. Also, production of this plants restricted by drought stress. Therefor the aim of this was investigation of drought stress effect on fruit and essential oil yield of different endemic coriander genotypes. In this regard, 14 coriander genotypes subjected to two levels of water treatments in two separate experiments of normal irrigation and water stress through randomized complete block design with three replications. This experiment was done in research farm of Etka organization at Varamin in 2014. Results showed that drought stress had significant effect on fruit and essential oil yield and percent of brock fruits. The difference between genotypes were significant for these features. Also, significant genotype × stress interaction effect shows that some of genotypes had different response to the water treatments.  The 357 genotype had the highest fruit yield in both normal irrigation and drought stress and genotype 230 had the highest essential oil yield in both normal irrigation and drought stress. MP, GMP, TOL and STI indices which are indicator of drought tolerance were gained by 357 and 230 genotypes. Further, SSI index which is indicator of drought susceptibility had high value for 158, 306 and 450 genotypes. In overall, 357 introduced as suitable genotype which had appropriate yield and drought tolerance.  Manuscript profile

  In order to study the Effects of PGPR Application Methods on essential oil percent and yield of lavender (<em>Lavandula angustifolia</em> L.) under drought stress conditions an experiment was performed at Islamic Azad University, Yadegar-e-Imam Khomeini (RAH) Shahre-Rey Branch. This experiment was carried out in a split plot arrangement with randomized complete block design in three replications. Experimental factors were included irrigation regimes as the main plot in three levels including 60, 110 and 160 mm evaporation from A class pan, and PGPR application methods in four levels including, Non application, root inoculation, application in irrigation water, and root inoculation+irrigation in irrigation water methods as the subplot. The results indicated that, simple effect of irrigation and PGPRS were significant on experimented traits but the interaction effects was significant on essential oil yield only. In this case, drought stress increased essential oil percent in lavender. So the highest amount of mentioned traits observed in irrigation at 160 mm and the lowest one obtained at 60 mm irrigation management. Based on findings, drought stress decreased the essential oil yield. Therefore the highest essence yield conducted at 60 mm and the lowest one gained at 160 mm irrigation regime&nbsp; management according to Class A evaporation pan. <br />&nbsp; Manuscript profile
