To study the effects of vermicompost and biofertilizer on quantity and quality (anethole, gama-himachalene and estragole content) of essential oil in anise (Pimpinella anisum L.), an experiment was conducted at Homand Research Station in Damavand, Iran in 2009. The factors were vermicompost (0, 5, 10 t/ha) and phosphatic biofertilizer (non-inoculated, inoculated seed and inoculated seed + spraying on soil in stem elongation stage). The experimental design was factorial based on randomized complete blocks design with nine treatments and three replications. According to the results, the highest essential oil content in seed and the maximum anethole content in essential oil were obtained at 10 t/ha and 5 t/ha vermicompost treatment, respectively. Also, the lowest gama-himachalene content and estragole content in essential oil was obtained at 5 t/ha vermicompost treatment. Phosphatic biofertilizer also showed significant effects on the mentioned characters, as the highest essential oil content in seed and anethole content in essential oil and the minimum gama-himachalene content and estragole content in essential oil were obtained in two times application of phosphatic biofertilizer. The intractions effect of biofertilizer and vermicompost on gama-himachalene content and estragole content in essential oil were significant, as the lowest gama-himachalene content and estragole content in essential oil were obtained at treatment of 5 t/ha vermicompost and two times application of phosphatic biofertilizer.

In order to study the effects of different nutrition systems (Organic and Chemical) on quantitative and qualitative characteristics of Fennel (Foeniculum valgare Mill.) under water deficit stress, an experiment was conducted as split plot in a randomized complete block design with three replications at the field station of Tarbiat Modares University in Peykan Shahr during cropping season of 2009. In this study, the main plots were three irrigation regime levels (Soil water content of 40% as the control treatment (C1), 60% (C2) and 80% (C3)) and sub-plots were different nutrition systems (10 ton/ha cattle manure, 10 ton/ha spent mushroom compost, 5 ton/ha cattle manure + 5 tan/ha spent mushroom compost and chemical fertilizer). Although the result showed that water deficit stress caused an increase in essential oil percentage, grain yield and essential oil yield decreased extremely under water deficit stress. The results showed that different nutrition systems significantly affected grain yield, essential oil yield and fenchone (p ≤ 0.01). Mean comparisons showed that using mushroom compost in favorable irrigation condition resulted in maximum essential oil yield (31.8 Kg.ha-1). This result was confirmed as the higher grain yield (1289.8 Kg.ha-1) obtained in the same treatment.

In order to study the effects of biofertilizers on quantity and quality of essential oil in fennel containing essential oil content and anethole content, fenchone content and limonene content in essential oil, an experiment was conducted at Hamand Research station in Damavand in 2005 and 2006. The factors were mycorrhizal inoculation (inoculated and non-inoculated), phosphatic biofertilizer (0, 30, 60 kg/ha) and vermicompost (0, 5 , 10 ton/ha). The experiment design was factorial experiment in the base of randomized complete blocks design with eighteen treatments and three replications. In addition, one plot was allocated to control in each replication and only chemical fertilizers (NPK: 90, 60 and 90 kg/ha) were used. Data obtained from control plots were used for comparing other plots. Mean comparison was carried out using Duncan multiple range test (at 5% level). Results showed that the highest essential oil content in seed and anethole content in essential oil and the lowest fenchone content and limonene content in essential oil were obtained with mycorrhiza treatment. Phosphatic biofertilizer also showed significant effects on essential oil content and anethole and limonene contents in essential oil (except fenchone content). The maximum essential oil content in seed and anethole content in essential oil were related to the plots with consumption of 60 kg/ha. The lowest limonene content in essential oil was obtained with consumption of 30 kg/ha phosphatic biofertilizer. The highest essential oil content in seed and anethole content in essential oil and minimum fenchone content and limonene content in essential oil were obtained with consumption of 10 ton/ha vermicompost. Comparison of control versus biofertilizer treatments was significant, as two biofertilizer treatments include inoculation with mycorrhiza, application of 30 kg/ha phosphatic biofertilizer and 10 ton/ha vermicompost and inoculation with mycorrhiza and application of 60 kg/ha phosphatic biofertilizer and 10 ton/ha vermicompost in relation to quantity and quality of essential oil were better than control.

To study the effect of sowing date on fennel CV. Soroksari, this research work was carried out on randomized complete block design with three replications. The effects of sowing dates of 6 of March, 20 of March, 4 of April, 19 of April, 5 of May, 21 of May, 5 of June and 21 of June, were studied on growth, development, seed yield and essential oil and anethole content of fennel CV. Soroksari. The results show that sowing dates hade significant effect on growth, development and quality and quantity of active substances of fennel. On the basis of the results the seeds were sown on 21 of May the seeds were germinated and developed faster. The highest plant (150.8 cm) and the largest number of branches per plant (10.1) was obtained from the plants were sown on 4 of April. There was no significant effect among 1000 seeds weight and essential oil content of different sowing dates. The largest seed yield (1864.3Kg/ha) and essential oil yield (91.3Kg/ha) was obtained from the seeds were sown on 4 of April. Anethole content were decreased from the plants were sown from 6 of March to 21 of June, the lowest amount (58.2%) was extracted from the plants were sown on 21 of June. According to the results of this resesrch trial the most suitable date for sowing of fennel cv. Soroksari is recommended 20 of March to 4 of April.
