“…Moreover, the use of seeds (Korczak and Grabowicz 2003) or silymarin extracts (Tedesco et al 2004) as feed supplement have been investigated. Some biometric parameters and the recorded DM yields were comparable to previous results (Ledda et al 2013), confirming the remarkable potential of this species for the production of biomass. This potential and its chemical composition, suggest us to consider the abundant yields from this species as a potential fodder source to be blended with other crop residues and forages according to the local context.…”

“…However, milk thistle is considered a weed in sowed annual legume pastures (Sulas et al 2008), waste areas, cereal crops, decreasing wheat yields (Khan et al 2009), and along roadsides (Karkanis et al 2011). On the other hand, milk thistle is currently being regarded as an interesting crop for bioenergy production in Mediterranean environment (Sulas et al 2008;Ledda et al 2013), and as a source for biodiesel production (Ahmad et al 2014); the biogas production from its biomass is under investigation (Andrzejewska J, unpublished). It is grown also as an ornamental plant (Bhattacharya 2011) and as a tolerant species for soils polluted by heavy metals (Rio-Celestino et al 2006;Perrino et al 2014).…”

Silybum marianum (L.) Gaertn. (milk thistle), grown as a medicinal plant in several countries, is considered as a weed in pastures and cereal crops but also as an interesting plant for biomass production. As an additional contribution to the full exploitation of a such promising species, two Sardinian populations of S. marianum were investigated for chemical composition, bioactive compounds and antioxidant properties at vegetative and reproductive stages. Dry matter yield was affected by the phenogical stage and differed between populations, ranging from 148 to 246 g plant -1 . Chemical composition did not differ between populations. Antioxidant capacity detected by means of ABTS [(2,2 0 -azinobis (3-ethylbenzothiazoline-6-sulphonic acid) diammonium salt)] and by DPPH (1,1-diphenyl-2-picrylhydrazyl) methods ranged from 3.45 to 5.42 and 3.83 to 6.32 mmol/ 100 g dry weight of Trolox equivalent antioxidant capacity, respectively. Differences in antioxidant capacity and bioactive compound contents in the different plant organs were found and also a significant linear correlation between antioxidant capacity and total phenolics and flavonoids, at flowering compared to vegetative stage. Research highlights antioxidant capacity in different organs of milk thistle and encourages the exploitation of biomass also as functional food, source of natural antioxidants and as a complementary fodder.

“…2) carried out over three growing seasons (from [2007][2008] to [2009][2010] in two sites in southern Italy (Sardinia), weed flora dynamics and oilseed rape yield were evaluated. This area is considered representative in the Mediterranean basin in terms of climatic, edaphic, and weed flora conditions, as well as different types of cropping systems [28][29][30].…”

Abstract:The oilseed rape conventional system can be moved to a more sustainable one by reducing herbicide application whilst ensuring at the same time effective weed control, maintaining oilseed rape yield, and quality and increasing profitability. Over three growing season periods, two field experiments at two different Southern Italy locations were carried out. In both sites, a conventional weed-control management system (recommended label dose), four alternative low-herbicide treatments, and an untreated control were compared. We monitored weeds and crop response to herbicide treatments, and calculated the net economic return, within site and year, for each treatment. In experiment 1, a half dose of herbicide did not show any significant difference in seed yield with respect to conventional treatment in two of three growing seasons. In experiment 2, compared with the conventional system, weedy control and the lowest applied herbicide dose treatment (25% of the recommended label dose) did not underline significant differences with regard to yield level. Net returns from the half dose of metazachlor herbicide were not significantly lower than net returns from conventional treatment in experiment 1 (on a three-year average 748 vs. 812 € ha −1 , respectively). Our findings suggest that the herbicide dose might be cut by at least 50% in order not to jeopardize negative effects on production and economic performances.

“…Furthermore, the high growth rates of milk thistle make it interesting for biomass production for energy (Sulas et al, 2008). Ledda et al (2013) noted that annual biomass production across years averaged about 10.000, 4.000, and 16.000 Kg ha −1 in cardoon (Cynara cardunculus L. var. altilis, Asteraceae), globe artichoke (Cynara cardunculus L. var.…”

Milk thistle [Silybum marianum (L.) Gaertn.] is an important medicinal-industrial plant. The medicinal compounds of milk thistle are derived from its seeds. The plant is commercially cultivated for the production of silymarin. Cultivation offers the opportunity to optimise achene yield and silymarin content. Furthermore, efforts should be made to develop new cultivars. The main objective of milk thistle breeding is to develop high yielding cultivars with elevated silymarin content. There are few developed cultivars of milk thistle (e.g. Argintiu, Budakalaszi, Szibilla, Khoreslo, Babak Castle, Mirel, Silma and Silyb). Different genotypes of milk thistle have variable amount of silymarin e.g. a 'Royston' genotype is rich in silymarin (6-10%). Further progress can be made by using the genetic diversity available in abundance in different genotypes. The main concern of the breeder should be to increase the yield and silymarin contents of the seeds. Asynchronous flowering and seed shedding are also major problems in milk thistle cultivation. At the time of harvest, the plants have flower heads at all stages of development resulting non-uniform maturation of seeds. Therefore, a breeding effort in milk thistle should be planned to obtain plants with simultaneous flowering and reduced crop losses. The developed cultivar Argintiu is characterised by simultaneous seed maturation in flower heads. The wild populations, as valuable gene pools, could be exploited for the improvement of milk thistle crop.
