This research was set up in 2013 in agroecological conditions of continental Croatia (3 different locations). The extperiment was set as a split-plot design in four replicates, with three levels of the main treatments of soil tillage (CT - plowing; MD - reduced multiple disk harrowing; SD - reduced single disk harrowing) and levels of subtreatment fertilization (F0 - control; F1 - standard KAN fertilization; F2 - fertilization with 5% urea solution; F3 - Profert Mara; F4 - Profert NGT; F5 - Thiofer; F6 - EM Aktiv). The highest camelina grain and biomass yield was achieved in the subtreatment F6 when using microbiological fertilizer EM Aktiv, regardless of the applied agrotechnics. After the harvest experiment, anaerobic batch co-digestion of camelina and cow manure was conducted under thermophilic conditions to determine camelina's potential for biogas production. The biogas potential of camelina was expressed as biogas and methane yields which ranged from 382.00 and 246.04 cm3 g-1 VS, respectively. If compared to maize which is often used as a standard for comparison of methane yields, maize methane yields are higher by 21 to 40%.

Istraživanje je postavljeno 2013. godine u agroekološkim uvjetima kontinentalne Hrvatske (3 različite lokacije). Pokus je postavljen po split-plot shemi u četiri ponavljanja, s tri razine glavnih tretmana obrade tla (CT - oranje; MD - reducirano višestruko tanjuranje; SD - reducirano drljanje jednom tanjuračom) i razinama gnojidbe podtretmana (F0 - kontrola; F1 - standardna gnojidba KAN-om; F2 - gnojidba 5% otopinom uree; F3 - Profert Mara; F4 - Profert NGT; F5 - Thiofer; F6 - EM Aktiv). Najveći prinos zrna i biomase kameline ostvaren je u podtretmanu F6 uz korištenje mikrobiološkog gnojiva EM Aktiv, neovisno o primijenjenoj agrotehnici. Nakon eksperimenta žetve, provedena je anaerobna šaržna kodigestija kameline i kravlje gnojovke u termofilnim uvjetima s ciljem određivanja potencijala kameline za proizvodnju bioplina. Bioplinski potencijal kameline izražen je preko prinosa bioplina i metana koji su se kretali od 382.00 odnosno 246.04 cm3 g-1 OT. U usporedbi s kukuruzom koji se često koristi kao standard za usporedbu prinosa metana, prinosi metana proizvedenog iz zrna kukuruza veći su za 21 do 40 %.
