Svake godine se u poljoprivrednoj proizvodnji, ali i u drugim delatnostima privrede stvore velike količčine otpada koji predstavalja organsku biomasu podesnu za korišćenje u energetske svrhe. U radu je ispitivana biomasa dva alternativna ţita (krupnik i korasan), tokom dvogodišnjih istraţivanja, 2015- 2016. godine, i mogućnost racionalnijeg korišćenja njihovih sekundarnih proizvoda u energetske svrhe. Rezultati su pokazali da je izmeĎu genotipova postojala je statistički značajna razlika u visini ispitivanog parametra, dok godina nije imala statistički značajan uticaj na visinu prinosa biomase. Pšenica korosan imala je veći prinos biomase, u proseku za dvogodisnji period, za 627 kg/ha odnosno za 59,22%. U skoroj budućnosti pogone koji bi za proizvodnju biogoriva koristili nehranljivi deo biljaka, odnosno ţetvene ostatke ratarskih (i ostalih) useva i zasada. Bitno je istaći da su u proteklim decenijama mnoge zemlje, pod snaţnim pritiskom da poboljšaju energetsku sigurnost sa aspekta zaštite ţivotne sredine, ali i da smanje zavisnost od uvoza, počele da razvijaju programe proizvodnje alternativnih biogoriva metana, etanola i biodizela iz proizvoda biljnog porekla. Every year, in agricultural production, but also in other economic activities. They create large amounts of waste which represents organic biomass suitable for use in energy purposes. The paper examined biomass two alternative cereals (spelt and khorasan), during two years, 2015-2016, and the possibility of more rational use their secondary products for energy purposes. The results showed that between the genotypes there was a statistically significant difference in the height of the tested parameter, while the year did not have a statistically significant impact on the yield of biomass. Wheat corosan had a higher biomass yield, on average for two years, by 6270 kg ha-1 or 59.32%. In the near future, it is necessary to perfect it industrial drives, which would for use biofuel production not a nutrient part of plants, or harvest residues field (and other) crops and plantations. It is important to point out that they have been in the past decades many countries, strong pressure to improve energy security from the aspect of environmental protection, but also to reduce the dependence on imports, began to develop programs production of alternative biofuels methane, ethanol and biodiesel from vegetable products of origin.
