| description | <i>Phragmites australis</i>, <i>Typha latifolia</i>, <i>T. angustifolia</i> and <i>Arundo donax</i> are tall wetland graminoids with the potential to replace fossil fuels under sustainable cultivation conditions. We investigated the biomethane (CH<sub>4</sub>) production of these four species, including four different genotypes of <i>P. australis</i>, which represent the high intraspecific diversity of European reed. All plants were grown under three different macronutrient supplies (no nutrients added, an equivalent of 75 kg N ha<sup>−1</sup> year<sup>−1</sup> added and an equivalent of 500 kg N ha<sup>−1</sup> year<sup>−1</sup> added). Biomethane production was measured in four independent batch digestion tests. Across all experiments, fertilization regime had little effect on CH<sub>4</sub> yield, which was on average 222 ± 31 L kg<sup>−1</sup> volatile solids (VS). The lowest yield was produced by <i>T. angustifolia</i> (140 L kg<sub>VS</sub><sup>−1</sup>) receiving no nutrients, while the highest yield was produced by <i>A. donax</i> (305 L kg<sub>VS</sub><sup>−1</sup>) in the highest nutrient treatment. The intraspecific diversity of <i>P. australis</i> did not affect biomethane production. All <i>P. australis</i> genotypes produced on average 226 ± 19 L CH<sub>4</sub> kg<sub>VS</sub><sup>−1</sup>, which, although high, was still lower than conventional biogas species. The biomass production of <i>P. australis</i> was less increased by fertilization than that of <i>Typha</i> sp. and <i>A. donax</i>, but all species had similar biomass without fertilization. |
