The aim of this study was to determine the effects of biological, organic, and chemical fertilizers on the uptake of nitrogen (N), phosphorus (P), potassium (K), grain yield, and essential oil in anisum (Pimpinella anisum L.). The experiment was carried out in the agricultural research field of Yasouj University in 2013, as a randomized complete block design with three replications. The treatments consisted of pure vermicompost (zero, 5 and 10 ton.ha-1), biofertilizer (Azotobacter, Barvar-1), biological phosphate fertilizer (Barvar-2) and the mixed Barvar-1 and Barvar-2, urea fertilizer, nano-biofertilizers and combined treatments of vermicompost (2.5, 5 and 7.5 ton.ha-1) with biological fertilizers Barvar-1,2 and the mixed Barvar-1,2. Results showed that the maximum nitrogen (1.390%) phosphorus (0.290%) potassium (1.866%) and chlorophyll a+b (0.410 ml.g-1) were obtained by the application of vermicompost at 10ton.ha-1. Also, maximum grain yield (595.90 kg.h-1) and essential oil yield (16.60 kg.h-1) were obtained by the application of vermicompost at 10ton.ha-1, showing no significant difference with combined treatment of vermicompost at 7.5 ton.ha-1 and Barvar-1,2. The minimum values for the study traits were obtained from the control treatment. According to the results, it appears that the application of 7.5 ton.ha-1 vermicompost is the best treatment to produce anise grain yield in organic system.

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.

To study the effect of drought stress and harvesting date on yield and essential oil production of Anise (Pimpinella anisum L.), a field experiment was conducted at College of Agriculture, University of Zanjan during spring of 2010. The experiment was conducted as a factorial based on complete randomized block design with three replications. The effects of water stress in three levels including control, drought stress at flowering and grain filling stages and two harvesting dates including harvest at hard dough and maturity stages were investigated. The results showed that the effect of drought stress on seed yield, total dry matter, number of umbrella in plant, 1000-seed weight, harvest index, essential oil percentage and essential oil yield was significant (p≤0.05). Majority of the mentioned traits except essential oil percentage significantly decreased (p≤0.05) under drought stress conditions but essential oil percentage increased. So the highest grain yield (622 kg/ha) and essential oil yield (20.95 kg/ha) were obtained in control treatment (full irrigation). The results also showed that the effects of harvest date on seed yield, 1000-seed weight, total dry matter, essential oil percentage and harvest index were was significant (p≤0.01). The highest seed yield (501 kg/ha) and essential oil percentage (3.85) were obtained in hard dough and maturity stages respectively.

Anise (Pimpinella anisum L.) is one of the aromatic and medicinal plants. Anethol is the most important component of its essential oil used in medicinal and food industries. The aim of this experiment was to determine the effect of vermicompost levels (0, 5 and 10 t.ha-1), mixture of Azotobacter, Azospirillum and Pseudomonas (inoculation and not-inoculation) and zeolite (0 and 4.5 t.ha-1) on essential oil content, composition and macro element contents of Pimpinella anisum. Experimental design was randomized complete blocks with factorial arrangement. Field experiment was conducted at Sanandaj Agriculture Research Station, in 2009. The results showed that vermicompost application improved essential oil content and yield, anethol and methyl chavicol percentage, nitrogen, phosphorus, and potassium content. Inoculating seeds with PGPR led to significant increment in all of the mentioned characters except for methyl cavicol percentage and potassium concentration. Zeolite application had significant effect on essential oil content, oil yield and anethol percentage but no significant effect on the other characters. The most favorable interaction treatment for essential oil production and phosphorus percentage was the PGPR inoculation combined with the highest level of vermicompost.

This study was carried out in the greenhouse of the college of Agriculture, 2009 to evaluate the effect of seed priming with polyethylene glycol and sodium chloride on germination and growth indices of Pimpinella anisum L. In this study, the effects of seed priming with a solution of polyethylene glycol at three levels (-5, -10 and -15 bar), seed priming in sodium chloride solution at three levels (-5, -10 and -15 bar) and control treatment (seed priming with distilled water) were investigated in a randomized complete block design with three replications. The results showed that the effect of seed priming with polyethylene glycol and sodium chloride on most traits including germination percentage, germination speed and seedling dry weight was significant (p ≤ 0/05).With decreasing water potential, germination percentage, germination speed and seedling dry weight (except for polyethylene glycol 10 bar) were significantly decreased (p ≤ 0/05) as results of seed priming with polyethylene glycol 10 bar were very close to the results of the control treatment.

Application of Biofertilizers in a sustainable agriculture system improves sustainability of yield especially in medicinal plants production. Anise (Pimpinella anisum L.) is a medicinal plant containing essential oils especially in its seeds. In this reserach, the effects of vermicompost and phosphate biofertilizer on yield and yield components in anise including plant height, number of umbels per plant, 1000 grain-weight, biological yield and seed yield were studied. The experiment was carried out at Homand research station - Iran in 2009. The factors were vermicompost (0, 5, 10 ton/ha) and phosphate biofertilizer (non-inoculated, inoculated seed and inoculated seed + spraying on soil in stem elongation). The experiment design was factorial experiment based on randomized complete blocks design with nine treatments and three replications. Mean comparison was carried out using Duncan multiple range test (P<0.05). Results showed that the highest plant height, umbel no./plant, biological yield, and seed yield were obtained from consumption of 10 ton/ha vermicompost but 1000 grain- weight were not affected by vermicompost significantly. Phosphate biofertilizer also showed significant effects on umbel no./plant, biological yield and seed yield (except plant height and 1000 grain-weight). The maximum umbel no./plant, biological yield and seed yield were obtained from two times consumption of phosphate biofertilizer. There were positive and synergistic interactions between factors like interactions between factors on biological yield. According to the results of this study, application of 10 ton/ha vermicompost and two times consumption of phosphate biofertilizer were determined as the most suitable treatments.
