In order to study the effects of Glomus hoi fungi, different levels of phosphorus and drought stress on some physiological characteristics of coriander (Coriandrum sativum L.), was conducted at Karaj Research Institute of Forest and Rangelands in 2006. Field experiment was carried out by a split factorial design with 4 replications. The factors were two level drought stress with irrigation after 30 mm water evaporation from evaporation pan (without stress conditions) and irrigation after 60 mm water evaporation (drought stress conditions) and also application and non-application of mycorrhiza, 0, 35 and 70 kgha-1 phosphorus fertilizer. The results showed drought stress has significant effect on water use efficiency, relative water content and proline accumulation rate (α=1%). Highest water use efficiency with 0.449 kgm-3 and proline accumulation rate with 6.767 mmol/ml were achieved under stress conditions and highest relative water content with %90.6 was achieved without stress conditions. Also, the results showed mycorrhiza and phosphorus had significant effects on water use efficiency (α=5%). Comparison of means showed that highest water use efficiency with 0.395 kgm-3 and 0.4 kgm-3 was achieved under application of mycorrhiza and application of 70 kgha-1 phosphorus, respectively. Relative water content and proline accumulation rate were not significantly affected due to phosphorus and mycorrhiza. The results showed that water use efficiency and proline accumulation rate were increased under drought stress conditions but relative water content decreased.

In order to study drought stress effect on quantitative and qualitative features of balm (Melissa officinalis L.) a research was conducted under field condition in Karaj, Iran in 2005. Experiment was conducted using Randomized Complete Block Design with 4 replications. Treatment included T1 (non stress), T2 (80%FC), T3 (60%FC), T4 (40%FC) and T5 (20%FC). Effect of drought stress on shoot yield, essential oil yield, percentage of essential oil, leaf and stem yield, height, tiller number, length and width of leaf, stem diameter and internodes was significant (α=0.001). Effect of drought stress on number of lateral stem was not significant. Comparison of treatment means showed that highest shoot yield was related to T1 (non Stress) (6469kg/ha), highest essential oil (12.970 kg/ha) and highest essential oil percentage (0.3012%) was related to T4 (40%FC) and T5 (20%FC), respectively. Highest height (65.32 cm), leaf length (6.27 cm) and width (4.58 cm) were related to T1 (non stress). Highest stem diameter was related to T5 (20%FC). It could be concluded that moderate drought stress is beneficial for balm essential oil.

In order to investigation of application methods of nitrogen fertilizer on essential oil content and composition of Balm, the experiment was conducted during 7 months in field condition at Alborze Research complex in 2004. This experiment was carried out at two levels of suspension nitrogen (4.5% and 6%) spraying on shoot and two levels of solid nitrogen (60 and 90 kg N/ha) application in soil with control. Treatment was implicated to three equal divisions. This experiment was carried out in complete randomized block design with 4 replications. In floral imitation, plants harvested and essential oil were extracted by water distillation. The essential oils were analyzed by GC and GC/MS. The results showed a significant difference (1%) among nitrogen rates application on essential oil yield. Identification of essential oil components showed that some compounds of the oil decreased with more application of nitrogen in two methods of nitrogen application, whereas some other compounds increased with most application nitrogen in both methods.

In order to study the effects of plant density on yield and yield components of safflower (Carthamus tinctorius)an experiment was conducted in Homand Research Station of Pasture under a completely randomized block design with 3 Replication in 2004. The treatment were 17, 25 and 35 Row Spacing (29, 20 and 14 Plant/m2, respectively). The results showed significant difference between densities for seed and biomass yield. Stigma yield also increased with high density. Seed per pappus and harvest index were decreased and number of pappus per plant was decreased significantly with high density. Therefore, safflower could be cultivated and produced with optimum yield under dry farming of Damavand Region.

Due to correction of dry farming system and possibilities for replacement of low efficient plants, Fennel as a domestic, tolerant and valuable medicinal plant was used. Fennel (Foeniculum vulgare) is a perennial medicinal plant, which grows in 7 month per year. Its values are for medical, spice, health and soil conservation effects. One of the important components of Fennel is Trans-anethol, which is in the seeds. This experiment was carried out in Damavand dry land region with using a Complete Randomized Blocks Design (CRBD), in three replications. The treatments were three geographic orients with 50–55% slopes. The result shows a significant different among the seed yield which planted in the different orients. The highest yield obtains at third year with 1527 Kgha-1 in north orient and the lowest yield with 196 Kgha-1, which was related to the south orient in the first year. The north orient produced most seed yield with 1170 Kgha-1 in mean three years which was significant different with south orient. The 3 years growth of Fennel in Damavand region shows its dry farming possibility. Thus, Foeniculum vulgare could be cultivated in dry farming system as a tolerant medicinal plant, which produces economic seed yield.

Determination of medicinal plants growth under different water stresses could be well guidance for cultivation of resistant plants in dry regions. In numerous glasshouse experiments under Completely Randomized Design (CRD), 5 medicinal plants species planted separately. Plantago psyllium, Achillea millefolium, Salvia officinalis, Calendula officinalis and Matricaria chamomilla were treated by well water (FC), 75%FC, 50%FC and 25%FC. Total dry matter, root weight, root length, shoot weight and height of medicinal plants were measured and analyzed separately. All of water and water stresses treatments were significant different in 1% probability. Among the medicinal plants in this experiment, Salvia officinalis and Achillea millefolium had the best growth in all water stresses treatments and conserved their freshness under sever water stress. These species could establish as the resistant medicinal plants in dry region or water deficit. Other species also completed their life cycle under sever water stress.

Natural habitates of Iran content of more than 7500 plant species which many of them are medicinal plants. It is as the germplasm and could be source of supplying and producing of medicinal plant for cultivation. Hypericum perforatum growing naturally in the north and west of Iran. In this study which have done in 1998 and 1999, samples of Hypericum perforatum at the flowering stage were collected from Gorgan, Nowshahr, Gilan in the north as the wetlands and Khalkhal in the west as the mountainous region. Hypericin as the secondary metabolite of Hypercicum perforatum were extracted by Soxhelt and measured by Spectrophotometer. Among the natural habitates, Gorgan and Gilan in 1998 with 2730 and 2584 PPM hypericin were significant with Nowshar anc Khalkhal respectively. Gilan, Gorgan and Nowshahr in 1999 with 2230, 2218 and 2120 PPM hypericin were significant with Khalkhal respectively. It seems hypericin production potential is high in regions with 250-400 m altitude and 500-900 mm rainfall and rich soil with organic and matter minerals.

Fluctuation of hypericin and yield in Hypericum perforatum was examined in Karaj Research Station in 1989. In this study chemical fertilizer, organic manure and combination of them were allocated in subplot, and plant density was allocated as main plot with 4,5.7 and 10 plant m?. In a split plot design under CRBD with 3 replication. Hypericin in the tops from the first harvest was extracted and measured by Soxhlet and spectrophotometer. Hypericin extraction was performed in two stages by CHCL3 and MeOH and measured by standard hypericin. The results showed that the combination of fertilizer and manure and also manure alone produced maximum hypericin, in the first harvest which were 2262 and 2197 ppm, respectively. Hypericin yields of the mentioned treatments with 4684 and 4534 gr/ha also showed significant difference with chemical fertilizer and control. The highest hypericin yield produced in 10 plant m density. Sum of hypericin yields for combination of manure and fertilizer treatment in two harvests reaches to 8094 gr/ha. It seems that combination of chemical fertilizer and manure by improvement of the soil physical, chemical and biological properties are able to improve hypericin content without any toxicity in this medicinal plant.

The effect of different amounts of fertilizers, N.P.K., manure, as well as mixture of them in an expriment was investigated at Alborz Research Center, karaj, IRAN in 1996-97. The effects of the fertilizers were studied on seed and shoot yield of Fenel (Foeniclum vulgare), system treatments include various levels of net chemical fertilizers, N.P.K., used in comercial or chemical agricultural systems as well as different levels of manure used in sustainable or organic systems, and a mixture of different ratios of fertilizers and manure used in mixture systems, and the control (with any fertilizer or manure). The expriment was condacted using completely Randomized Block Exprimental design with three replications. The results of first and second years of the expriment showed that in chemical systems, seed and straw had a higher performace in treatments 5(N=160 P= 128 and K=160 Kgha') and No.4 (N=120, P=96 and K=120 Kgha), which equalled 901.33 and 4326.2 Kgha?, respectively while in organic systems related to treatment No.13(40 tonh' manure) that resulted 947.17 and 5147.2 Kgha'', While the highest yield of seed and straw in mixture agroecosystems belonged to treatment No.10 (a mixture of 25 tons of manure with N=60, P=48 and K=60 kgha! chemical fertilizers) with seed an straw yield 1182.67 and 6627 Kgha, respectively. In comparison with the control treatment, seed and straw yield increase were: 69.37% and 31.49% for net chemical system; 122.23% and 101.43% for mixture system; and 77.98% and 56.44% for organic system respectively. The combined analysis of data from two consecutive years of the expriment indicated that shoot biomass of plant, seed & straw yield in mixture systems in comparison to net chemical and organic systems, rised significantly, which is comparisonly more tangible in the second year. This results could be related to that mixture of chemical fertilizer and manure, which is a nutritive source for the plant and plays an important role in improvment of chemical and physical structure of soil.
