The research conducted 2021–2023 evaluated the potential of different corn hybrids for biogas and biomethane production, specifically focusing on how varying levels of mineral nutrition influence these outputs. The study examined four corn hybrids with different maturity groups: Amaros, Bogatyr, KWS 381, and Carifols. The experimental design included three levels of macrofertilizers, which were an unfertilized control, an N90P60K60 application, and an N120P90K90 application. Additionally, it incorporated three microfertilizer treatments, consisting of a control without application and two different combinations of YaraVita and YaraTera pre-sowing seed treatments paired with foliar spraying in the 3-5 leaf stage.
\nThe primary objective was to estimate energy output, based on the methodological assumption that one kilogram of corn dry matter yields 0.6 m³ of biogas containing fifty-eight percent methane. The findings revealed a clear hierarchical increase in productivity among the hybrids, progressing from Amaros to Carifols. The Amaros hybrid exhibited the lowest outputs, whereas the Carifols hybrid consistently demonstrated the highest productivity. Under optimal nutrition, Carifols achieved peak yields of up to 8886.0 m³/h\u0430 for methane and 15589.5 m³/h\u0430 for biogas, making it the most intensive hybrid in the study.
\nThe application of mineral fertilizers significantly enhanced energy outputs across all tested varieties. The highest macrofertilizer dose of N120P90K90, particularly when combined with the microfertilizer treatments, consistently produced the highest absolute yields. The data showed a direct positive correlation between the doses of macrofertilizers and the percentage increase in biogas output. Applying the N90P60K60 dose increased biogas output per hectare by 15-20 % compared to the control, while the N120P90K90 dose increased it by 21-30 %.
\nAn important observation from the correlation analysis was the inverse relationship between baseline hybrid productivity and relative fertilizer responsiveness. The least productive hybrid, Amaros, showed the highest relative sensitivity to fertilizers, achieving a yield increase of approximately thirty percent at the maximum fertilizer dose. In contrast, the highly productive Carifols hybrid demonstrated a slightly lower relative increase of 22-24 %, despite producing the highest absolute volumes of biogas and biomethane.
\nUltimately, the study underscores that optimizing biogas and biomethane production from corn requires selecting high-yielding hybrids and applying tailored mineral nutrition strategies that account for the specific genetic responsiveness of the chosen variety to maximize both absolute yield and fertilizer efficiency.
