In order to evaluate the density, population and insect fauna diversity and agronomical yield in intercropping faba bean (Vicia faba L.) andcoriander (Coriandrum sativum L.), a field experiment was conducted based on a randomized complete block design with three replications at the farm located in Nagadeh, West Azerbaijan province, Iran during growing season in 2012-2013. Treatments included 75 percent faba bean + 25 percent coriander, 50 percent faba bean + 50 percent coriander, 25 percent faba bean + 75 percent coriander and their monoculture. Results showed that the maximum population of pest obtained under monoculture, while the maximum population of biological predators was observed under 50 percent faba bean + 50 percent coriander, respectively. The highest seed yield and biological yield of faba bean were obtained in monoculture and the lowest grain yield and biological yield were achieved in 75 percent faba bean + 25 percent coriander, respectively. The results showed that the maximum seed yield and biological yield of coriander were obtained at monoculture, and the minimum seed yield and biological yield of coriander were achieved in 75 percent faba bean + 25 percent coriander, respectively. There was no significant difference between treatments in the essential oil percentage but the highest essential oil yield was higher than other treatments. The highest (1.58) and the lowest LER (1.40) values was obtained from 75 percent faba bean + 25 percent coriander and 50 percent faba bean + 50 percent coriander, respectively.

To investigate the effects of mycorrhizal fungi, phosphatic biofertilizer and manure application on yield and quantitative and qualitative criteria of coriander an experiment was conducted at Khoramabad during growing season of 2013. The experiment design was applied as factorial layout based on a randomized complete block design with 18 treatments and three replications. The factors were mycorrhizal inoculation in two levels (non-inoculation and inoculation), phosphate biofertilizer in three levels (zero, 35 and 70 kg/ha)and manure in three levels (10, 20 and 30 ton/ha). Result indicated that mycorrhizal inoculation and phosphate biofertilizer had significant (one percent) effects on plant height, inflorescence number per plant, 1000 seed weight, seed yield, biomass yield, essential oil and essential oil yield of coriander. Mean comparison showed that the highest effects among factors were obtained by mycorrhizal inoculation on all parameters. The highest seed yield )1780.67 kg/ha), biomass yield (3831.7 kg/ha) and essential oils (0.4 percent) were obtained of inoculation with mycorrhiza, consumption of 70 kg/ha phosphate biofertilizer and 20 ton/ha manure and they were 80, 51 and 135 percent more efficient than chemical control, respectively. Positive and synergistic interactions were obtained between mycorrhizal inoculation × phosphate biofertilizer on seed yield.

In order to study of use advantage in the intercropping system fennel (Foeniculum vulgare Mill) and fenugreek (Trigonella foenum-graecum L) in different ratios of intercropping and sole cropping, an experiment with use replacement and additive intercropping based on randomized complete block design with three replications was conducted at the Research Station of Faculty of Agriculture, University of Zanjan, Iran, during growing season 2012. Treatments included additive intercropping in three levels (100 percent fennel + 33, 66 and 100 percent fenugreek), replacement intercropping in six levels (1:1, 1:2, 2:1, 2:2, 1:3, 3:1), Sole fennel and Sole fenugreek. Results showed that the highest grain yield of Fenugreek was obtained in pure stand of Fenugreek and the lowest of mentioned trait was obtained in the 75 percent fennel + 25 percent fenugreek (3:1) replacement series. Also the highest and the lowest fennel grain yield were obtained in 100 percent fennel + 33 percent fenugreek additive series and 25 percent fennel + 75 percent fenugreek (1:3) replacement series respectively. yield of essential oil at 100 percent fennel + 33 percent fenugreek additive series were higher compared with sole cropping. The highest Land Equivalent and Relative Value Total obtained from 100 percent fennel + 33 percent fenugreek additive series. The highest Actual Yield Loos or gain (AYL) and intercropping advantage (IA) obtained from 25 percent fennel + 75 percent fenugreek (1:3) replacement series. Aggressively index revealed that in most sowing ratios fennel was dominant and fenugreek was defeated.

German chamomile (Matricaria chamomilla) is one of the most important industrial medicinal plant. Inthis experiment the effects of foliar application of salicylic acid in different levels (0, 10-2, 10-4, 10-6) wereinvestigated on the floral traits and essential oil content of three ecotypes (Italian, Tehran, Zabol) ofGerman chamomile. The results showed that maximum percentage of essential oil (1.5 weight percent)was obtained from Zabol ecotype as sprayed with 10-4 M of salicylic acid and Maximum oil yield (0.085gr per pot) was obtained from Italy ecotype in which treated with 10-2 M salicylic acid. Among theidentified sesquiterpenes of essential oil, Chamazulene, E-β Farencene and α-Bisabolol oxide A weresignificantly varied based on the experimental treatments. The highest amount of Chamazulene (3.789percent) was recorded in Italian ecotype in which treated with 10-2 M salicylic acid, and the same ecotypeproduced highest amount of farencene (2.264 percent) when treated with 10-2 M Salicylic acid. Theapplication of salicylic acid in concentrations of 10-4 and 10-6 M increased the α-Bisabolol oxide A(respectively, 70.907 and 73.482 percent) Compare with control. Generally, contrary to essential oil yieldcomponent, only the essential oil yield and its constituent were affected by salicylic acid application andthe responses of experimental ecotypes was varied.

A field experiment was conducted based on randomized complete block design with three replications at the Agricultural Research Station of Payamenoor University of Nagadeh, Iran during growing reason of 2009-2010. Treatments included bean and dill monoculture, row intercropping (one row of dill + one row of bean), strip intercropping (two rows of bean+ four rows of dill and four rows of bean+ two rows of dill) and intra- row intercropping (50% dill+ 50% bean). The results showed that the highest and the lowest grain yield and biological yield of bean were achieved in row intercropping and intra- row intercropping (50% dill+ 50% bean), respectively. The plants were planted as replacement method. The highest grain yield (1630 kg/ha) and biological yield (3593 kg/ha) of bean were obtained at row intercropping and the lowest grain yield (414 kg/ha) and biological yield (870 kg/ha) of bean were achieved in intra- row intercropping, respectively. The results showed that the maximum grain yield (340 kg/ha) and biological yield (1926 kg/ha) of dill were obtained at monoculture and the minimum grain yield (340 kg/ha) and biological yield (1926 kg/ha) of dill were achieved in strip intercropping (four rows of bean+ two rows of dill intercropping), respectively. The highest essential oil percentage and essential oil yield were obtained by row intercropping, compared with other treatments. The highest (1.9) and the lowest LER (0.80) values were obtained from row intercropping and intra- row intercropping patterns, respectively. The maximum population of pest obtained under monoculture, while the minimum population of biological predators was observed under intra- row intercropping, respectively.

Fennel is one of the oldest herbs and possesses appealing flavor and beneficial medicinal effects. Fennel(Foeniculum vulgare Mill.) belongs to the Apiaceae family and its essential oil and seeds are used to flavor foods including meats, ice cream, candy, baked goods and condiments. The increasing commercial value of fennel necessitates the need to develop elite ecotypes with high essential oil content and other desired breeding and market traits. In this study fifty ecotypes of fennelfrom different part of Iran were collected and days to 70% pasty seed and essential oil content in two years and essential oil components were studied. The stage of pasty seed is the best time for essential oil extracting with the highest quantity. The results indicated that the ecotypes of Sari, Kaleibar, Qazvin, Chahestan and Haji Abad are late bearing, ecotypes of the Moqan, Kohin, Meshkin Shahr, Alamot, Khalkhal, Damavand, Ardabil, Marvdasht, Kashan, Givi, Khash and Fozve are middle bearing plants, while the remaining ecotypes were early bearing plants. As average of two year, ecotypes with the highest essential oil content (more than 3.5% per dry mater) were Razan, Fozve, Marvdasht, Kashan, Sari, Kaleibar and Arak (3.96, 3.69, 3.68, 3.66, 3.65, 3.65 and 3.54%), respectively. The GC-MASS results showed that maximum value of limonene is observed in the ecotype of Sanandaj, the maximum value of fenchone is observed in the ecotype of Sari, the maximum value of transe-anethole is seen in the ecotype of Khash and the maximum value of methyl chavicole belongs to the ecotypes of Kaleibar.

Tuberose is one of the most important floral crops in Iran. Long spikes of fragrant flowers make it excellent for cut flower. Due to the beauty and sweet fragrance of flowers, it used in all seasons for flower arrangements. Production of high quality flowers and vase life extension is important for competition in world markets. For this reason this research was conducted on Polianthes tuberosa var Double base on factorial experiment in RCB (randomized complete block design) with three replications. Both gibberellic acid (GA3) and benzyl adenine (BA) were sprayed on bulbs and foliage of plants at four concentration levels. Results showed that gibberellic acid and benzyl adenine treatments had significant differences in all of the measured indices at one percent level. Gibberellic acid increased stem and rachis length in some concentrations and also accelerated flower stalk emerge. Benzyl adenine increased stem diameter, floret numbers and vase life and preceded flowering. Both of these plant growth regulators improved water uptake by cut flowers and increased diameter of second floret but decreased ethylene production of the flowers. Essential oils of flowers were extracted by solvent extraction method. Both of the plant growth regulators had negative effects on essential oils of flowers, but in 1000 mg.l-1 of BA essential oils of flowers were higher than other concentrations.
