A series of experimental studies of the biogas production potential of two intermediate crops (winter rye and winter triticale) grown in Ukraine were carried out. The dry matter and organic dry matter contents of both crops were determined and compared with corn silage in terms of similar indicators. The methane yield of 98 NlCH4/kg and 68 NlCH4/kg of fresh weight for winter rye and winter triticale, respectively, was experimentally determined. In terms of absolutely dry ash-free weight, the methane yield was 333 NlCH4/kgDM and 365 NlCH4/kgDM for winter rye and winter triticale, respectively. The methane potential of the analysed samples and corn silage was compared. It is shown that winter rye, at the achieved yield, has a higher specific methane yield than winter triticale, both per unit area of arable land (5400 Nm3CH4/ha for rye versus 4600 Nm3CH4/ha for triticale) and per unit fresh weight (120 Nm3CH4/t for rye versus 65 Nm3CH4/t for triticale). It was found that in terms of average methane yield per unit area, the cultivation of the studied hybrids of winter rye and triticale is comparable to the cultivation of corn silage, and therefore can be recommended for biogas production as a substrate alternative to corn silage.
