“…In contrast to the first year of development, a similar picture tends to be seen in the S. integrifolium accessions studied, with all plants now showing shoot growth. Based on the fact that shoot growth is a necessary step for generative growth in Silphium, it can be shown that this has also been observed elsewhere [58]. In S. perfoliatum, this picture is clearer, since, in the first year of cultivation, the proportion of shooting plants was lower than or completely absent in the S. integrifolium accessions studied.…”

“…Kowalski et al (2004) documented no generative development in the first year in their developmental description of S. integrifolium [50]. Contrary to this, Schiffner et al (2021) describes that S. integrifolium also shows generative development depending on the sowing date, and the available development time, until the end of the vegetative phase of the first year [58]. Sil shows a higher tendency towards generative growth than Sii whereas, in both accessions, the seed filling phase no longer occurred completely.…”

“…In S. perfoliatum, this picture is clearer, since, in the first year of cultivation, the proportion of shooting plants was lower than or completely absent in the S. integrifolium accessions studied. This allows for the hypothesis that S. perfoliatum is more dependent on vernalization than S. integrifolium or that both species show different strategies for generative propagation [26,58]. 4.3.3.…”

For higher sustainability in biomass production the use of new perennial species can lead to sustainable progress in the energy production and manufacturing industry. During the last decades, two different species of Silphium were discussed for biomass production. However, some questions regarding their cultivation and different uses are still to be answered. In this study, two accessions of Silphium perfoliatum L. and Silphium integrifolium Michx. were investigated during the year of establishment, and the first generative year for the phenotypic characteristics and suitability for cultivation, under Central European field conditions. Intra- and interspecific comparisons were made with special attention to their growth kinetics. While cup plant (S. perfoliatum) is well known as a potential biomass crop in Europe, silflower (S. integrifolium) is still unknown. In intraspecific comparison, S. integrifolium shows a more uniform development than S perfoliatum. In parallel, the development of S. perfoliatum accessions is temporally shifted, so that the S. perfoliatum accessions differ in the length of their phases of generative growth and onset of senescence in comparison to S. integrifolium. To make these results applicable, an improvement proposal was made to the existing BBCH scale for S. perfoliatum. In addition, an adaptation was conducted on S. integrifolium.

“…Genetic improvement of both cup plant and silflower is in its infancy and genetic and genomic resources are being developed [199,207]. Progress has been made in understanding the genetic basis of self-compatibility [208], the physiology and ecophysiology of germination [209][210][211].…”

Ecological Intensification of Food Production by Integrating Forages

Forage crops have the potential to serve multiple functions, providing an ecological framework to sustainably intensify food production, i.e., ecological intensification. We review three categories of forages (annual forages, perennial forages, and dual-use perennial crops/forages) we believe hold the greatest promise for ecologically intensifying food production. Annual cover crops can provide additional forage resources while mitigating nutrient losses from agricultural fields when they are intercropped with, interseeded into, or following an annual crop, for instance. The integration of perennial forages either temporally, such as annual crop rotations that include a perennial forage phase, or spatially, such as the intercropping of perennial forages with an annual cash crop, provide weed suppression, soil quality, and yield and crop quality benefits. Dual-use crops/forages can provide forage and a grain crop in a single year while providing multiple ecological and economic benefits. However, tradeoffs in balancing multiple functions and limitations in reducing the risks associated with these practices exist. Advancing our understanding of these systems so we can overcome some of the limitations will play a critical role in increasing food production while promoting positive environmental outcomes.
