“…Decreasing concentration of N, P, and K over the growing season months (Tables 5 and 6) was consistent with previous reports (Sanderson et al, 1999;Adler et al, 2006;Kering et al, 2011). Biomass Ca was higher in the early growing period compared to the late growing period for Year 1 whereas it was constant in Years 2 and 3 (Tables 5 and 6).…”

The maximum biomass yield of switchgrass (Panicum virgatum L.) usually is achieved with one seasonal autumn harvest. However, information is limited on the influences of winter harvesting on annual biomass yield and on quality parameters impacting conversion into bioethanol. Accordingly, the objectives of this study were to assess: (i) yield of standing field cured biomass at monthly intervals through winter, (ii) year‐round elemental composition of biomass, and (iii) associated year‐round soil nutrient status. An unfertilized ‘Kanlow’ switchgrass planting established in 1998 was used for this study conducted from November 2007 to October 2010. The experimental treatment was monthly harvest from November to the following March and year‐round monthly sampling of biomass (except April) and soil for chemical analyses. The 3‐yr mean dry matter yield of winter harvests was 5.94Mg ha−1, ranging from 3.88 Mg ha−1 in the winter of 2007–2008 to 7.55 Mg ha−1 in 2009–2010. Monthly biomass yield differences were significant in Years 1 and 3 but not in Year 2. Concentrations of biomass elements and soil nutrients changed with various degrees over the 3 yr. Concentrations of ash, cell wall components, and mineral nutrients, except P, K, and S, did not change appreciably across winter months. Early winter harvests resulted in less yield loss compared to late winter harvests. These findings will be valuable in harvest management for switchgrass biomass production.

“…In a article by Arundale et al (2013) who summarized multiyear trials in Illinois (USA) a positive, though small, yield response to N fertilization was highlighted with high rates (around 200 kg N ha À1 ). Several studies have, however, found no influence of N fertilization on crop yield at harvest (Himken et al, 1997;Heaton et al, 2004;Christian et al, 2008;Strullu et al, 2011;Behnke et al, 2012;Kering et al, 2012;Maughan et al, 2012;Larsen et al, 2013).…”

Influence of soil texture and crop management on the productivity of miscanthus (Miscanthus × giganteus Greef et Deu.) in the Mediterranean

et al. 2014

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.

Effects of growth-promoters on the productivity of Arundo donax L. (NileFiber™) grown as a purpose-grown biofuel feedstock in Nova Scotia

Abstract:Arundo donax L. is a perennial grass species of Mediterranean origin. Its high biomass yield potential in its native climate has contributed to A. donax being an important biofuel feedstock crop. This study investigates the potential of A. donax as a purpose-grown biomass feedstock for advanced biofuel production in Nova Scotia. The effects of nine different growth-promoters (bacterial and fungal species, a seaweed extract, and a lipo-chitooligosaccharide) and two inoculation methods on A. donax biomass productivity were investigated through three experimental trials: one greenhouse and one field trial inoculated by a post-planting application of the supplements around the plant stem ("soil drenching") and one greenhouse trial with inoculation by root soaking just prior to planting (2016). The survival of A. donax over the winter was also evaluated over two winter seasons (2014-15 and 2015-16). Penicillium bilaii illustrated the most consistent positive effects on biomass productivity across experimental trials, and the plants' higher phosphorus concentrations suggest that P. bilaii was helping the plant access soil phosphorus. The root soaking inoculation method resulted in more positive effects in measured growth parameters compared with the soil drench method. Despite a very mild winter in one of the 2 years tested, A. donax did not successfully overwinter in the field in either year. The presence of growthpromoters did not enhance biomass productivity substantially in the field. Moreover, due to its low over-
