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.

The main objective of this study was to assess the effects of different levels of vermicompost and nitrogen on qualitative and quantitative yield of chamomile (Matricaria chamomilla L.). The experimental design was factorial based on Randomized Complete Blocks Design (RCBD) with three replications, conducted in Research Institute of Forests and Rangelands during spring 2010. Treatments were consisted of four levels of vermicompost (5, 10, 15 and 20 tons per hectare) and nitrogen of four levels (30, 60, 90 and 120 kg per hectare). The measured traits included number of flowers per plant, diameter of flower, dry and fresh flower yield, essential oil percentage and Chamazulene content in essential oil. Results showed that vermicompost had significant effects on dry flower weight and essential oil percentage (α ≤ 0.05%). In addition, it had significant effects on dry and fresh flower yield and Chamazulene (α ≤ 0.05%). The effect of nitrogen on the number of flower (α ≤ 0.05%) and essential oil percentage (α ≤ 0.01%) was significant. The results of interaction effects showed significant differences for the number of flower, dry flower yield, dry flower weight, essential oil percentage and Chamazulene.

In order to study the effect of organic manure and biofertilizer on some morphological traits and yield in coriander (Coriandrum sativum L.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with twelve treatments and three replications at homand research station in Damavand of Iran in 2010. The factors were cattle manure in four levels (5, 10, 15 and 20 ton/ha) and plant growth promoter bacteria in three levels (inoculation with azotobacter, inoculation with azospirillum and inoculation together). Besides, these treatments with a control treatment (without fertilizer) were also evaluated using a randomized complete blocks design with thirteen treatments and three replications. Results showed that the highest umbel no./plant, 1000 seed weight, and seed yield were obtained with consumption of 15 ton/ha cattle manure. Plant growth promoter bacteria also showed significant effects on umbel no./plant and seed yield (except 1000 seed weight). The maximum umbel no./plant were obtained with two treatments of inoculation with azotobacter and inoculation with azospirillum and seed yield were obtained with azospirillum inoculation. Interactions between factors on umbel no./plant and 1000 seed weight were significant. Differences between control and other treatments were significant, as umbel no./plant in treatment of 15 ton/ha cattle manure application and inoculation together and also, 1000 seed weight and seed yield in treatment of 20 ton/ha cattle manure application and inoculation with azospirillum were higher than control.
