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.

“…They are also seen as an important component of climate mitigation measures and one of the resources for displacing fossil fuels [35][36][37]. In addition to the growth characteristics and biomass production of the selected energy crops (Salix, Populus, Miscanthus and Arundo) [38][39][40][41][42][43][44][45][46], our study focuses on their potential to be used for phytoremediation purposes, i.e., phytostabilization, rhizofiltration and phytoextraction of toxic pollutants -especially heavy metals and metalloids from the soil that are accumulated in their extensive root system and aboveground biomass [47][48][49].…”

Contamination of soil by toxic elements is a global issue of growing importance due to the increased anthropogenic impact on the natural environment. Conventional methods of soil decontamination possess disadvantages in forms of environmental and financial burdens. This fact leads to the search for alternative approaches of remediation of contaminated sites. One such approach includes phytoremediation. Phytoremediation advantages consist of low costs and small environmental impact. Several fast-growing energy plant species are suitable for phytoremediation purposes. Our article focuses on the phytoremediation potential of energy woody crops of Salix and Populus, and energy grasses Miscanthus and Arundo, which are grown primarily for biomass production. This approach links the environmentally friendly and economically less demanding remediation approach with the production of the local sustainable form of energy that decreases dependency on external energy supplies. Energy plants are able to provide high biomass yields in a short period of time, they are resistant against abiotic stress conditions and have the ability to accumulate toxic substances, thus helping to restore the desirable soil properties. The phytoremediation research is very interdisciplinary in its nature. In order to implement phytoremediation practices together with bioenergy successfully, it is crucial to involve site owners, local people, farmers, technology providers and consultants, remediation experts, sustainability assessors, regulatory agencies and certification bodies, biorefineries, financial sponsors, NGOs and other voluntary organizations. Some disadvantages and challenges of phytoremediation are also indicated.

Slovakia is acountry with limited natural resources, therefore its essential task is to search for new renewable sources of energy to reduce its dependence on imported fossil fuels. The results of research confirmed that the Common Reed (Phragmites australis(Cav.) Trin.) has considerable potential of phytomass production and energy storage (calorific value reached 17,448 J g−1d.w.). Biomass production of Common Reed under natural conditions of the lower Liptov region reached 12.702 tons of a dry mater per hectare with the calculated energy storage of 221.622 GJ ha−1. The average biogas production was 351.31 l kg−1of a dry matter of which the methane (CH4) content represents 185.21 l kg−1(52.72%). With regards to the values of combustion heat, a calorific value and the production of methane it can also be noted that in case of Common Reed it is more profitable to focus on direct combustion of biomass than the production of biogas and methane.
