“…Miscanthus yields may vary considerably depending on the environmental conditions of the study site, the management practices and harvest time (Brosse et al, 2012). Studies in Europe and United States and summarized by Heaton et al (2010) Italy (Ercoli et al, 1999;Cosentino et al, 2007) and 38-44 Mg ha À1 in Greece (Danalatos et al, 1996(Danalatos et al, , 2007.…”

Biomass productivity is the main favorable trait of candidate bioenergy crops. Miscanthus 9 giganteus is a promising species, due to its high-yield potential and positive traits including low nutrient requirements and potential for C sequestration in soils. However, miscanthus productivity appears to be mostly related to water availability in the soil. This is important, particularly in Mediterranean regions where the risk of summer droughts is high. To date, there have been no studies on miscanthus responses under different soil conditions, while only a few have investigated the role of different crop managements, such as irrigation and nitrogen fertilization, in the Mediterranean. Therefore, the effects of contrasting soil textures (i.e. silty-clay-loam vs. sandy-loam) and alternative agricultural intensification regimes (i.e. rainfed vs. irrigated and 0, 50, 100 kg ha À1 nitrogen fertilization), on miscanthus productivity were evaluated at three different harvest times for two consecutive years. Our results confirmed the importance of water availability in determining satisfactory yields in Mediterranean environments, and how soil and site characteristics strongly affect biomass production. We found that the aboveground dry yields varied between 5 Mg ha À1 up to 29 Mg ha À1 . Conversely, nitrogen fertilization played only a minor role on crop productivity, and high fertilization levels were relatively inefficient. Finally, a marked decrease, of up to À40%, in the aboveground yield occurred when the harvest time was delayed from autumn to winter. Overall, our results highlighted the importance of determining crop responses on a siteby-site basis, and that decisions on the optimal harvest time should be driven by the biomass end use and other long-term considerations, such as yield stability and the maintenance of soil fertility.

“…Nutrient use efficiency (NUE) was expressed as the ratio between dry matter production and nutrient content (g/g), according to Beale and Long (1997). Therefore, NUE indicates the total biomass produced per unit of nutrient absorbed (Cosentino et al, 2007a). From July to January, cellulose, hemicellulose and lignin contents of miscanthus and giant reed were determined using the Van Soest method (1991).…”

Seasonal nutrient dynamics and biomass quality of giant reed (Arundo donax L.) and miscanthus (Miscanthus x giganteus Greef et Deuter) as energy crops

The importance of energy crops in displacing fossil fuels within the energy sector in Europe is growing. Among energy crops, the use of perennial rhizomatous grasses (PRGs) seems promising owing to their high productivity and their nutrient recycling that occurs during senescence. In particular, nutrient requirements and biomass quality have a fundamental relevance to biomass systems efficiency. The objective of our study was to compare giant reed (Arundo donax L.) and miscanthus (Miscanthus × giganteus Greef et Deuter) in terms of nutrient requirements and cellulose, hemicellulose and lignin content. Hence, the aim was to identify, in the Mediterranean environment, the optimal harvest time that may combine, besides a high biomass yield, high nutrient use efficiency and a good biomass quality for second generation biofuel production. The research was carried out in 2009, in San Piero a Grado, Pisa (Central Italy; latitude 43°41' N, longitude 10°21' E), on seven-year-old crops in a loam soil characterised by good water availability. Maximum above-ground nutrients content were generally found in summer. Subsequently, a decrease was recorded; this suggested a nutrient remobilisation from above-ground biomass to rhizomes. In addition, miscanthus showed the highest N, P, and K use efficiency, probably related to its higher yield and its C4 pathway. Regarding biomass quality, stable values of cellulose (38%), hemicellulose (25%) and lignin (8%) were reported from July onwards in both crops. Hence, these components appear not to be discriminative parameters in the choice of the harvest time in the Mediterranean environment. In conclusion, our results highlighted that, in our environment, a broad harvest period (from late autumn to winter) seems suitable for these PRGs. However, further research is required to evalu ate the role of rhizomes in nutrient storage and supply during the growing season, as well as ecological and productive performances in marginal lands, in particular where water availability may be a limiting factor.

“…In optimal conditions of the southern Europe, the production of dry biomass of the aboveground organs is about 25-30 t*ha -1 (Angeliny et al, 2009), while irrigated conditions in Portugal increased the production at level of the 36 t ha -1 (Clifton-Brown et al, 2001), 34-38 t*ha -1 in Italy (Ercoli et al, 1999;Cosentino et al, 2007) and 38-44 t*ha -1 in Greece (Danalatos et al, 2007). For practical use of knowledge about the productivity of plantations of fast-growing grasses Miscanthus it is important the analysis of inputs (especially the cost of growing the planting material) from an economic point of view.…”

Growing energy crops is one of the possibilities of using temporarily, respectively persistent unused agricultural land. In Slovakia, 44% (1,064,625 ha) of secondary and other land of the total land fund can be use also for establishment plantations of energy crops. The aim of this paper is to evaluate the impact of the planting material energy crop Miscanthus on canopied growth and productivity of the growth. Mortality of the individuals and the ability of the individuals to create aboveground organs in the year of the establishment and dynamics biomass production in the following years have been assessed. The growth of fast-growing crop Miscanthus was established on a field experimental basis. Two genotypes: Miscanthus × giganteus (planting materials were rhizomes) and Miscanthus sinensis Tatai (planting materials were in vitro seedlings) have been observed. Relatively high mortality of the individuals (31%) was confirmed in rhizomes plantation. In the first year of cultivation, the growth of the Miscanthus × giganteus created clusters with total average number 26.07 stems per cluster with count yield biomass 11.10 t*ha -1 within the research area. The growth of the Miscanthus sinensis Tatai was full canopied at the end of the growing period in the year of its establishment. Miscanthus sinensis Tatai created average 37.60 stems per cluster with count yield biomass 10.80 t*ha AbstraktPestovanie energetických rastlín je jednou z možností, ako využiť dočasne, resp. trvalo nevyužívanú poľnohospodársku pôdu. Na Slovensku je 44% (1 064 625 ha) sekundárnej a ostatnej pôdy z celkového pôdneho fondu možné využiť aj na zakladanie plantáží energetických rastlín. Cieľom príspevku je zhodnotiť vplyv výsadbového materiálu energetickej byliny Miscanthus na celkovú zapojenosť a produktivitu porastu, zhodnotiť mortalitu jedincov a ich schopnosť vytvárať nadzemné orgány v roku založenia porastu a dynamiku produkcie biomasy v nasledovných rokoch. Porast bol založený na poľnej pokusnej báze Boli sledované dva genotypy: Miscanthus × giganteus (výsadbový materiál boli rizómy) a Miscanthus sinensis Tatai (výsadbový meteriál boli sadenice in vitro). Pri Miscanthus× giganteus bola potvrdená pomerne vysoká mortalita (31%). Rastliny vytvorili v prvom roku pestovania trsy s celkovým priemerným počtom 26,07 stebiel na trs s prepočítanou úrodou biomasy 11,10 t*ha . Po piatom vegetačnom roku (2014) dosiahol porast Miscanthus priemernú produkciu 28.60 t*ha -1 suchej biomasy. Porast založený z rizómov nedosiahol plné zapojenie v roku založenia plantáže a bolo potrebné doplniť výsadbu v nasledujúcom roku.
