“…Silphium is a yellow flowering crop with high ecological value, and which is particularly suitable as an energy plant species owing to its low maintenance requirements and high biomass (15-19 t•ha −1 ) and biogas yields. The crop is productive for around 15 years and can be adapted to regions with similar climate conditions, like Europe [23,29]. Silphium has the potential to be a pioneer plant used in the restoration of degraded land [30].…”

Biogas production and use is one of the pillars of the EU strategy for fossil fuels replacement via renewable energies. In Poland, the most commonly used crop for biogas production is maize. There are many factors limiting the cultivation of this crop, which is why alternative plants are sought. The aim of the present paper was to assess the effect of establishing a plantation using seeds, seedlings, and various harvest dates on biogas production from Silphium perfoliatum L. (Silphium) and from two phenotypes of Sida hermaphrodita L. Rusby (Sida). Harvesting was conducted in the second (2017) and third year of crop growth (2018). These crops were harvested in June and at the beginning of October as a two-cut strategy. Additionally, Silphium was harvested in early autumn as a one-cut strategy. Specific biogas yield (SBY) and specific biomethane yield (SMY) were estimated using the modified Baserga method. The biogas yield per hectare (BY) was calculated. The crop species, method of establishing a plantation, as well as the date and the number of harvests had a significant effect on the content of the selected chemical components; however, significant differences in terms of SBY were not found for the two-cut strategy. In the case of Silphium, approximately 40% more BY was produced for the two-cut strategy compared to the one-cut strategy. The BY was found to be significantly affected by the biomass yield; markedly higher BY can be obtained from Silphium and the average amount obtained in one year was 8598 m3 ha-1 while 4759 m3 ha-1 was obtained from Sida.

“…For example, in the USA Albrecht and Goldstein [4] reported yields of 11 Mg•ha −1 from 10,000 plants ha −1 in Wisconsin, Zilverberg et al [3] reported 25 Mg•ha −1 from 110,000 plants ha −1 in South Dakota, and Asseffa et al [2] observed 10.5 Mg•ha −1 from 28,000 plants ha −1 in South Dakota. In Europe, Wever et al [8] reported yields of 17.2 Mg•ha −1 from 40,000 plants ha −1 in Germany, and Šiaudinis et al [9] achieved 21.9 Mg•ha −1 from 20,000 plants ha −1 in Lithuania.…”

The North American genus Silphium is receiving global attention for its potential in the development of new food, forage, and industrial crops, including cellulosic biomass for biofuel. Little is known about the effect of plant population density on biomass production in large, coarse perennial forbs. Our objective was to evaluate the effect of variation in plant density on biomass production and stand morphology of cup plant (Silphium perfoliatum L.). Plant population densities of 17,000, 34,000, and 68,000 plants ha −1 were evaluated for biomass production in a single-harvest per annum system for three years at Brookings, SD and Arlington, WI. Biomass increased linearly by 43% between the low and high density at Brookings; whereas, at Arlington, response to variation in plant density was year dependent. Shoots plant −1 was inversely related to plant density with linear regression explaining >95% of the variation. Our results strongly suggested that further studies of effects of plant population density on biomass production in cup plant should include evaluation of, in addition to, densities higher than 68,000 plants ha −1 .

“…Recently there have been efforts to better incorporate the ecological benefits of Silphium species into improving habitat restoration and agricultural practices (Van Tassel et al 2017). Because of these benefits, combined with high biomass accumulation requiring relatively few inputs, species of Silphium show promise for forage and biogas production (Ustak and Munoz 2018;Wever et al 2019) or as a perennial oil seed crop (Van Tassel et al 2017). Additionally, the incorporation of native wildflowers in prairie restoration projects or as buffer strips among agriculture fields are thought to improve pollinator abundance (Isaacs et al 2009).…”

Patterns of genetic variation in a prairie wildflower, Silphium 1 integrifolium, suggest a non-prairie origin and untapped variation 2 available for improved breeding.Abstract 9 Premise 10 Understanding the relationship between genetic structure and geography provides 11 information about a species' evolutionary history and can be useful to breeders interested 12 in de novo domestication. Silphium integrifolium is an iconic perennial American prairie 13 wildflower that is targeted for domestication as an oilseed crop. Germplasm in the existing 14 breeding program is derived from accessions collected in restricted geographic regions. We 15 present the first application of population genetic data in this species to address the 16 following goals (1) improve existing breeding programs by characterizing genetic structure 17 and (2) identify the species geographic origin and potential targets and drivers of natural 18 selection as the range has expanded. 19 Methods 20We developed a reference transcriptome to use as a genotyping reference for dozens of 21 samples from throughout the species range. Population genetic analyses were used to 22 describe the distribution of genetic variation and demographic inference modeling was used 23 to characterize potential processes that have shaped variation. Divergence outlier scans for 24 selection and associations with environmental variables were used to identify loci linked to 25 putative targets and drivers of natural selection. 26 Key results 27 Genetic variation partitions samples into three geographic clusters. Patterns of variation 28 and demographic modeling suggests that the geographic origin of the species is in the 29 American southeast. Breeding program accessions are from the region with lowest observed 30 genetic variation. 31 Conclusions 32 This iconic prairie species did not originate within the modern prairie. Breeding programs 33 can be improved by including accessions from outside of the germplasm founding region, 34 which has relatively little genetic variation compared to the south and east. The observed 35 geographic structuring of variation coupled with the identified targets and environmental 36 drivers of adaptation during range expansion can guide future collecting efforts towards 37 wild populations with beneficial agronomic traits.38
