To investigate the effects of vermicompost and phosphate biofertilizer Barvar-2 on quantitative and qualitative yield of Silybum marianum L., a factorial experiment was conducted in a randomized complete block design with three replications in a field near Ardebil city in 2018-2019 crop year. Vermicompost was used at five levels (0, 10, 20, 30, and 40 ton.ha-1) and biofertilizer at two levels (inoculation and non-inoculation). The results showed that seed yield, 1000-seed weight, number of seeds per capitule, number of capitules per plant, biological yield, oil yield, silymarin yield, and flower fresh weight were significantly affected by different levels of vermicompost. Also, the application of phosphate biofertilizer Barvar-2 had a significant effect on all traits except inflorescence diameter. The highest amount of traits in the vermicompost treatment was obtained in the application of 40 tons.ha-1. However, there was no statistically significant difference for the traits including number of seeds per capitule, oil, silymarin, and silybin percentage, oil yield, and number of inflorescences in the application of 40 and 30 tons vermicompost per hectare. In biofertilizer treatment, the highest amount of traits was observed in inoculation with this fertilizer. The highest silybin percentage (16.81) and silymarin yield (37.61 kg.ha-1) were obtained in the application of 40 tons vermicompost per hectare and the lowest one (16.12% and 30.56 kg.ha-1, respectively) at the control level of vermicompost.

This study was aimed to evaluate the quantitative and qualitative performance of different populations of Milk Thistle (Silybum marianum L.( under the influence of autumn and spring planting season. Therefore, a split plot experiment was conducted including autumn and spring planting as main plots and four local populations (Shush, Poldoktar, Khoram Abad and Aleshtar) and a crop cultivar as sub plots. The study was carried out in the Faculty of Agriculture, Lorestan University, for two years 2014-2015. In addition, the native and crop populations of this species in Aleshtar were compared in a randomized complete block design. Based on the results, there was a significant difference between spring and autumn planting seasons. The highest plant height (107 cm), capitol diameter (44 mm), number of grains in capitol (78) and grain yield (1000 kg ha-1) were obtained in autumn planting. The interaction effect of planting season and population type showed that the highest content of silymarin (22 mg/g of dry weight) and silybin (3.9 mg /g of dry weight) was obtained from the crop cultivar in autumn planting. The comparison between native and crop populations in Aleshtar region showed that the highest content of silybin (4.2 mg /g of dry weight) and silymarin (more than 21 mg / g of dry weight) was recorded for native Aleshtar population compared with other populations. In general, it was determined that the highest and lowest quantitative and qualitative performance of Milk Thistle in the temperate region of Khorramabad was obtained in autumn planting, and the highest content of silymarin and silybin was recorded for the native Aleshtar population compared with other populations.

Silybum marianum L. is an annual or biannual herbaceous species from Asteraceae which is important in medicinal industry. The main components of this species are various flavonolignans consisting of silibinin, isosilibinin, silychristin, silydianin and taxifolin that are known as silymarin. This species is used in treatment of heart diseases, diabetes, blood cholesterol, liver diseases (jaundice, cirrhosis and hepatitis), and gallbladder disease. In this research, different organs of Silybum marianum (young and old leaves, stem, root, inflorescence and seeds) were separately collected during the different months in the Gorgan region and then total flavonoid, silymarin content, and the amount of silymarin components were measured by HPLC method. Our results showed that the highest amounts of total flavonoid were observed in the seed and inflorescence samples and then in the stem samples. Meanwhile the effect of time on flavonoid content and also the effect of sampling month and organ factors on flavonoid content were significant. Data from the HPLC analyses revealed that the silymarin compositions, observed in this study, were similar and the main difference among samples was the amount of silymarin composition. The highest amount of silydianin was observed in the stem sample; however the amount of other components were higher in the seed sample. According to the results, Gorgan is a suitable region for the cultivation of Silybium marinum and since the stem of this species contain significant amounts of silymarin, it could be considered as an optimal source of the production of pharmaceutical substances.
