Seeds of eight populations of Anthemis pseudocotula Boiss., A. tinctoria L. and A. triumfettiiL. were cultivated as single plant by using three replicated split plot design for planting date as main factor and the populations of three species as minor factor on the basis of randomized block design on two dates (May, and July). The study was conducted at Alborz Research Station in 2011. Each experimental unit included six rows with a distance of 50 cm and 10 plants per row, with a distance of 40 cm. During the growth period, the traits of crown length and width, plant height, number of flowers, fresh and dry weight were evaluated for the populations of three species. Analysis of variance showed that there were significant differences between two dates of cultivation (p<0.05), as well as among populations and their interaction effects (p<0.01) for all traits. Mean comparison of traits showed that crown length and width, plant height, number of flowers, fresh and dry weight of Anthemis pseudocotula were higher as compared to Anthemistinctoria and A. triumfettii. According to the obtained results, the vegetative and generative traits of Anthemis pseudocotula from 20172-Golestan population were superior as compared to other populations. However, no significant differences were found for the populations of Anthemis tinctoria. Our results clearly showed that Anthemis pseudocotula had lower GDD as compared to other species and flowered earlier. The percentage of essential oil ofAnthemis tinctoria was higher thanthat ofAnthemis pseudocotulaandAnthemistriumfettii.

Pumpkin (Cucurbita pepo) is an annual plant that has been introduced to Iran in recent years. Its effective components are used to cure some diseases such as prostat hyperplasia, control of taenia, Arleriosclerosis, regulation of alimentary canal and hormonal balance especially in women and strengthening men sexual appeal in advanced countries. Phosphate is one of the macro-elements affecting root growth and development and seed and fruit yield. On the other hand, regarding to its high and indefinite shoot development, planting density is highly important to get the highest yield. An experiment was conducted to study planting density and phosphate in a faeturial experiment level. Three stand density as 10000, 13000, 16000 per ha and four pure phosphate as 0, 50, 100, 150 kg/ha-1 were based on RBCD with three replications, in Feyz-Abad research station, Qazvin in 2004. Results showed 10000 density had significant effectiveness on node number, shoot length, leaf number, leaf dry weight and lateral shoot number. Phosphate also affected significantly the highest leaf dry weight which was achieved by using 150-kg/ha-1 phosphate. The highest node number has been produced by 100 kg/ha-1 phosphate. 10000 plant/ha caused the highest fruit yield, seed number and seed dry weight. Also, 100 kg/ha-1 phosphate treatment leaded to the most seed number and the highest seed dry weight. Plant population and phosphate fertilizer had no significant difference on the oil content.

In order to study the effect of nitrogen levels and plant density on seed yield, essential oil and oil content of Coriander seeds, an experiment was conducted in agricultural station of Qazvin and natural resources research center in 2005. The experiment was laid out by adopting split plot design with four replications, main plots were nitrogen: 30, 60 and 90 kg/ha and subplots were plant density including: 20, 30, 40 and 50 plant/m2. Seed yield, essential oil, oil content and yield were determined. Results showed nitrogen and plant density effected on Seed yield, essential oil, fatty acids. With increasing of nitrogen to 60 kg/ha, there was a significant increase in seed yield. The seed yield was decreased with more nitrogen. But the highest essential oil content and fatty acids were obtained with 90 kg nitrogen /ha. With increasing of plant density, seed yield and oil content had a significant decrease. Seed yield and oil content were higher in 30 plant/m2, while essential oil was higher in 40 plant/m2 that there was no difference with 30 plant/m2 in this respect. Comparing of treatments showed that the highest seed yield and essential oil yield were obtained by using 60 kg nitrogen/ha while there was the highest essential oil content, content and yield of oil with the application of 90kg nitrogen/ha with 30 plant/m2.
