“…As WPM yields differ strongly depending on the species composition, location, and cultivation year it is not possible to talk about exact yield figures at species level (WPS), and rather provide ranges of the yield potential. [23,29,30,33,34,84,99,101,109] For this study, an average of this data, considering only studies with a minimum of 3 cultivation years, is assumed, resulting in annual average WPM dry matter yields of 10.9 Mg ha −1 .…”
