Milk thistle (Silybum marianum (L.) Gaertn) has been used in medicine since ancient times, but it has been cultivated as a medicinal plant only in recent decades. The ripe fruit of milk thistle contains flavonoids, which are used to prepare anti-hepatotoxic drugs. The main purpose of this study was to substantiate the effects of irrigation and row spacing on growth, seed yield and the content of active substances (silybin and silymarin) in milk thistle. The results showed that the suitable amount of irrigation was 20 mm and the appropriate row spacing was 25 cm.

Salinity Levels

Milk thistle (Silybum marianum) is used as a medicinal plant in the treatment of liver diseases. In order to investigate germination and seedling growth in S. marianum subjected to NaCl, a three replicated experiment was carried out in a randomized complete block design in the laboratory of Gorgan University of Agricultural Sciences and Natural Resources. Treatments included seven salinity levels (50, 75, 100, 125, 150, 175 and 200 mM) and a control (distilled water). Germination percentage (GP), mean germination time (MGT), seed-ling vigour index (SVI), shoot, root and seedling weight were measured. The effect of salinity levels was significant on GP, SVI, MGT and seedling weight and length (p ≤ 0.01). However, the NaCl concentration effect was not significant on shoot : root length ratio and or shoot : root weight ratios. Results showed that germination decreased when salinity increased, while MGT increased. MGT was 1.75 times higher than in the control at the highest salt concentration. MGT difference was not significant between 75 mM NaCl and con-trol, while it dramatically increased by increasing the NaCl concentration from 150 to 200 mM NaCl. Reduc-tion slope and salt tolerance index (STI) were estimated for germination (0.54 and 231.9) and seedling stage (0.24 and 237.4). According to the results, milk thistle could be considered as a valuable medicinal plant in fairly salinized areas.

The World

Milk thistle, Silybummarianum (L.)Gaertn.,is grown throughout the world for its hepatoprotectant flavonolignans, known collectively as silymarin. Silymarin is found primarily in the seeds. Milk thistle was grown outdoor field for determination of plant growth, seed yield under various variants of row spacing (30x20, 40x20 and 50x20) and different sowing dates (May 20, May 30 and June 10). Plant height measured (ranging from 43.5-82.6cm)and yield (ranging from 5.24-70.31cg/ha) that there was a significant difference among different sowing dates and row spacing.Mongolian Journal of Agricultural Sciences Vol.13(2) 2014: 73-75

Milk thistle (Silybum marianum (L.) Gaertn.) is a promising new crop in the Mediterranean region. Its seeds contain silymarin, a complex of flavonolignans, which is widely used in the pharmaceutical industry, mainly to produce dietary supplements. To meet the increasing demand for milk thistle, the production and productivity of milk thistle should also be optimized by employing adequate cultivation practices. In the present study, a two-year field experiment was conducted to assess the effects of plant density and a plant growth regulator on milk thistle crop growth, seed yield, and silymarin accumulation under Mediterranean semi-arid conditions. Our results showed that plant density had a significant impact on milk thistle crop growth and seed yield. The main crop characteristics, such as height, aboveground biomass, and seed yield were greatest when plant density was the highest. Increased plant density significantly reduced the silymarin content only in 2018. In contrast, mepiquat chloride (MC) treatment did not affect the following traits: plant biomass, relative chlorophyll content, silymarin content, and production. Nevertheless, mepiquat chloride reduced the plant height by 7.9%–14.8%, depending on the application rates and growth conditions. Moreover, the impact of climatic conditions on milk thistle production and quality was significant, since the lowest values of silymarin content and seed yield were recorded in the year with drought conditions during the period from March to May.

Aim. To investigate the content of heavy metals in the seeds of milk thistle (Silybum marianum (L.) Gaertn.) and in the product of its processing – oil. To reveal possible changes in the concentration of heavy metals in the years of cultivating this plant. Methods. The fi eld and spectrometric methods were applied; the results were processed using the technologies, common for agriculture, plant production and statistics. Results. The content of heavy metals in the seeds of milk thistle was defi ned. It was determined that their concentration exceeds maximal acceptable coeffi cient for the medicinal plant material. It was established that in 2013 the seeds of milk thistle accumulated several times more Ba, Ca, Fe, Mg, Mo, Sr, V compared to the indices of 2014, while Al, Co, Ag were found only in the samples of the seeds, harvested in 2013. Conclusions. As the regulatory documents regarding many relevant elements, which belong to heavy metals, do not specify maximal accept- able coeffi cients for the content of the latter in the medicinal plant material, it is reasonable to conduct complex studies, involving the specialists of relevant fi elds, in order to stipulate this gradation. In the Kyiv region the milk thistle plants accumulate a large amount of such heavy metals as cadmium, manganese, strontium, and zinc, which exceeds maximal acceptable degrees of accumulation and testifi es to partial pollution of region soils. It was established that the concentration of the main part of heavy metals in the product of processing milk thistle – oil – is decreased to the value under the threshold of analytic devices. This fact proves the pros- pects of growing milk thistle for industrial processing purposes.

Active Substances

The consumption of herbal-based supplements, which are believed to have beneficial effects on human health with no side effects, has become popular around the world and this trend is still increasing. Silybum marianum (L.) Gaertn, commonly known as milk thistle (MT), is the most commonly studied herb associated with the treatment of liver diseases. The hepatoprotective effects of active substances in silymarin, with silybin being the main compound, have been demonstrated in many studies. However, MT can be affected by toxigenic micro-fungi and contaminated by mycotoxins with adverse effects. The beneficial effect of silymarin can thus be reduced or totally antagonized by mycotoxins. MT has proven to be affected by micro-fungi of the Fusarium and Alternaria genera, in particular, and their mycotoxins. Alternariol-methyl-ether (AME), alternariol (AOH), beauvericin (BEA), deoxynivalenol (DON), enniatin A (ENNA), enniatin A1 (ENNA1), enniatin B (ENNB), enniatin B1 (ENNB1), HT-2 toxin (HT-2), T-2 toxin (T-2), tentoxin (TEN), and zearalenone (ZEA) seem to be most significant in MT-based dietary supplements. This review focuses on summarizing cases of mycotoxins in MT to emphasize the need for strict monitoring and regulation, as mycotoxins in relation with MT-based dietary supplements are not covered by European Union legislation.

Yield Attributes

The objective of this experiment is to determine the effect of nitrogen fertilizer dosses on the yield attributed and seed yield of silybum during rabi season 2018-19 towards development of new agrotechnology. For this purpose, different fertilizer dosses were evaluated and their responses were ascertained with respect to yield attributes and economic yield of silybum. The field experiment was conducted to study the effect of four treatments of different nitrogen doses viz., T1 (control), T2 (NPK @ 80:80:60/ha), T3 (NPK @ 100:80:60/ha) and T4 (NPK @ 120:80:60/ha kg NPK ha-1) with the spacing 50*50cm row to row & plant to plant respectively with three replicates. The result showed significant influence of higher nitrogen doses T4 (NPK @ 120:80:60/ha kg NPK ha-1) produced higher economic seed yield (9.35 q/ha-1 ­­) followed by T3 (NPK @ 100:80:60/ha) NPK  produced (8.50 q/ha-1 ­) and  T2 (NPK @ 80:80:60/ha) produced (6.60 q/ha­­­) seed yield, and lowest seed yield (2.55 q/ha) were recorded in T1(control) without fertilizer. The observation recorded revealed highest economic yield attribute  like; plant height (288.00 cm), canopy  ( 102.1 * 99.2 cm),  number of leaf (10) and highest seed yield (9.35 q/ha) were recorded in T4 application of NPK @ 120:80:60/ha kg NPK ha-1 as compared to other treatments. Therefore, recommended application of NPK @ 120:80:60/ha kg NPK ha-1 is recommended for quality cultivation of silybum to get higher economic yield and return.
