Abstract
Miscantus giganteus is a perennial highly productive grasst hat is grown as a agro- energetic crop because it has a large annual biomass production. The overall strategy of growing agro-energetic crops is that the specific surface area receives more energy with less production costs and that the cultivation of energy crops is not in competition with food production. In recent decades due to the increase in demand fore new able energy and rehabilitation of degraded lands, there is great interest in plant species that have large annual biomass production, which are tolerant to biotic and abiotic stress and requires minimal investment in agricultural technology. The paper presents the results of the productivity parameter miscan thus in the two study years, 2012 and2013, fromearly spring harvest. The average yield of miscanthus in the studied period amounted to 5.78t/ha. Data analysis evidenceda statistically significant difference in the yield of biomass between these years. Miscanthus b...iomass yield was statistically significantly higher in 2013 than In 2012 for 5.90t/ha, respectively 209.54%.

Miscantus giganteus je višegodišnja visokoproduktivna trava koja se gaji kao agroenergetski usev jer ima veliku godišnju produkciju biomase. Opšta strategija gajenja agroenergetskih useva ja da se sa određene površine zemljišta dobije što više energije uz što manje troškove proizvodnje i da gajenje energetskih useva ne bude u kompeticiji sa proizvodnjom hrane. Poslednjih decenija zbog porasta potražnje za obnovljivim izvorima energije i sanacija degradiranih zemljišta, vlada veliko interesovanje za biljne vrste koje imaju veliku godišnju produkciju biomase, koje su tolerantne na biotički i abiotički stres i za koje su potrebna minimalna ulaganja u agrotehniku. U radu su prikazani rezultati ispitivanja parametra produktivnosti miskantusa u dve ispitivane godine i to u 2012. i 2013 iz rano prolećne žetve. Prosečni prinosi miskantusa u istraživanom period iznosili su 5,78 t/ha. Analizom dobijenih podataka evidentna je statistički značajna razlika u prinosu biomase između istraživanih godi...na. U 2013. godini prinos biomase miskantusa bio je statistički značajno viši u odnosu na 2012. godinu i to za 5,90 t/ha odnosno za 209,54%.
