Abstract
Cilj ovog rada bio je prikazati proizvodnost biomase i suhe tvari sirka za bioplin u uvjetima 2013. godine u Dalju te procjenu prinosa bioplina i metana po jedinici površine. Ispitivanje proizvodnosti biomase i suhe tvari provedeno je metodom poljskog pokusa, a procjena prinosa bioplina i metana korištenjem referentnih prinosa po kilogramu suhe tvari biomase iz literaturnih podataka. Ostvareni prinosi suhe tvari biomase sirkova kretali su se u rasponu od 6,8t/ha do 17,0 t/ha, ovisno o genotipu, a procijenjeni prinosi bioplina od 4110 nm3/ha do 10276 nm3/ha i metana od 2090 nm3/ha do 5225 nm3/ha , također ovisno o ispitivanom genotipu sirka. Relativno niski prinosi suhe tvari biomase u odnosu na proizvodni potencijal ispitivanih genotipova može se objasniti nepovoljnim okolišnim uvjetima tijekom provođenja poljskog pokusa. Rezultati ispitivanja proizvodnosti biomase i suhe tvari mogu smatrati visoko relevantnima za manje povoljne okoliše, a procijenjeni prinosi bioplina i metana trebaju se prihvatiti s oprezom jer je primijenjena formula procjene na temelju prinosa bioplina po jedinici suhe tvari biomase, bez uvažavanja razlika u kvaliteti biomase među ispitivanim genotipovima. Posebnosti kvalitete pojedinih genotipova nisu bile ispitane u vrijeme izrade ovoga rada zbog ograničenosti istraživačkih resursa
Abstract (english)
The aim of this study was to present biomass and dry matter productivity of sorghums for biogas in the conditions of 2013 in Dalj, and to estimate the biogas and methane yield per unit area. Investigation of biomass and dry matter yield was conducted by field trial and estimation of biogas and methane yield by using reference yields per kg od dry matter of the biomass from the literature data. Realized average dry matter yields varied from 6.8t/ha to 17,0 t/ha, depending on the sorghum genotype. Estimated biogas yields varied from 4110 nm3/ha to 10276 nm3/ha and methane yield from 2090 nm3/ha to 5225 nm3/ha, depending on the genotype too. Yields of dry matter of the biomass were relatively low in comparison with the potential productivity of investigated silage sorghums due to unfavorable environmental conditions during the study. The biomass and dry matter productivity may be considered highly relevant to less favorable environmental conditions, but estimate yields of biogas and methane should be considered with caution due to method of estimation – i.e. “flat rate” coefficients regardless the genotypes’ herbage quality specialties. The genotypes herbage quality specialties’ were not analyzed due to limited research resources..
