“…When comparing the methane yield of brown knapweed to the other non-food plants (lupine, nettle, rhubarb, hemp), shown in Table 17, the methane yield of brown knapweed was almost double per hectare. The methane yields per hectare of giant knotweed are in the same range as reported previously, for example, for timothy-clover grasses (2 800-3 800 m 3 ha -1 ) and hemp (3 100 m 3 ha -1 ) (Pakarinen et al 2011a) (Table 17).…”

Esitetään Jyväskylän yliopiston matemaattis-luonnontieteellisen tiedekunnan suostumuksella julkisesti tarkastettavaksi yliopiston Ylistönrinteellä salissa YAA303 syyskuun 27. päivänä 2013 kello 12.Academic dissertation to be publicly discussed, In this thesis, the methane production potential of traditional and novel energy crops was evaluated in boreal conditions. The highest methane yield per hectare was achieved with maize (4 000-9 200 m 3 CH4 ha -1 a -1 ) and the second highest with brown knapweed (2 700-6 100 m 3 CH4 ha -1 a -1 ). Recently, the most feasible energy crop, grass, produced 1 200-3 600 m 3 CH4 ha -1 a -1 . The specific methane yields of traditional and novel energy crops varied from 170-500 l kg -1 volatile solid (VS). The highest specific methane yields were obtained with maize, while the novel energy crops were at a lower range. The specific methane yields decreased in the later harvest time with maize and brown knapweed, and the specific methane yield of the grasses decreased from the 1 st to 2 nd harvests. Maize and brown knapweed produced the highest total solid (TS) yields per hectare 13-23 tTS ha -1 , which were high when compared with the TS yields of grasses (6-13 tTS ha -1 ). The feasibility of maize and brown knapweed in co-digestion with liquid cow manure, in continuously stirred tank reactors (CSTR), was evaluated. According to the CSTR runs, maize and brown knapweed are suitable feeds and have stable processes, producing the highest methane yields (organic loading rate 2 kgVS m -3 d -1 ), with maize at 259 l kgVS -1 and brown knapweed at 254 l kgVS -1 . The energy balance (input/output) of the cultivation of the grasses, maize and brown knapweed was calculated in boreal conditions, and it was better when the digestate was used as a fertilizer (1.8-4.8 %) than using chemical fertilizers (3.7-16.2 %), whose production is the most energy demanding process in cultivation. In conclusion, the methane production of maize, grasses and novel energy crops can produce high methane yields and are suitable feeds for anaerobic digestion. The cultivation managements of maize and novel energy crops for biogas production require further research.

“…Other studies have also shown that Jerusalem artichoke yield can be high and can reach even 30 Mg • ha -1 [41]. The study conducted by Pakarinen et al [11] showed that the amount of Jerusalem artichoke yield varied from 7 to 16 Mg DM • ha -1 and was much lower than yields obtained in this research. The distinct diversity of the amount of yield of the Jerusalem artichoke varieties in respective years which was determined in this research finds confirmation in literature [42][43].…”

“…Jerusalem artichoke is a species that can be used in various branches of the food, pharmaceutical, chemical, and power industries [9][10]. Topinambour biomass is used as a raw material for production of biogas and biodiesel [11][12]. The Jerusalem artichoke, also called earth apple, is a perfect source of fructose and a raw material for ethanol production [13].…”

The aim of our research was to assess the effectiveness of phytoextraction of heavy metals from sewage sludge by 'Rubik' and 'Albik' varieties of Jerusalem artichoke. The 6-year field experiment involved four levels of fertilization with sewage sludge at doses of 0,10,20,40, . The research evaluated the amount of Jerusalem artichoke yield as well as the uptake and use of heavy metals by the Jerusalem artichoke varieties.It was established that increasing doses of sewage sludge had significantly increased the yield of the Jerusalem artichoke varieties. Increasing doses of sewage sludge also had a significant effect on the increase in the content of heavy metals in aboveground parts of plants. The highest heavy metal uptake with the yield of the Jerusalem artichoke varieties was observed at a dose of 60 Mg DM • ha -1. Among the tested varieties of Jerusalem artichoke, Albik had higher yield, higher content and uptake of heavy metals, and greater recovery of these elements as compared to Rubik. Therefore, based on the obtained research results, Albik can be recommended for phytosequestration of heavy metals from sewage sludge amended soil.

“…Delaying time of flowering can be used to optimize biomass production where the whole plant is used. Late-flowering cultivars of maize are chosen for boreal conditions in order to optimize whole-crop biomass and quality for forage or bioenergy use (Pakarinen et al, 2011). Similarly, transforming tobacco with an Arabidopsis FLC construct that delayed flowering resulted in a significant increase in dry matter production (Salehi et al, 2005).…”

“…Crop diversity offers other opportunities. Fibre hemp (Cannabis sativa L.) can be used for industrial fibre or bioenergy, and provides reliable yields at high latitudes (Pakarinen et al, 2011). Flax (Linum usitatissimum L.) fibre commands premium prices in the fabric market, and the seed residue is valuable as a functional food.…”
