Laboratory methods to measure the amount of methane gas evolved in the fermentation process require specialized equipment and are long-lasting and expensive. Therefore a number of methods are developed to estimate the efficiency of biogas and methane from the chemical composition of the substrate. The aim of this study was to compare different methods to estimate the efficiency of methane from the silages made from whole plant corn. The study was based on test results of silage from whole plant corn included in various publications, which deal with the production of methane (determined by fermentation “Bacht System”) and complete chemical composition. On the basis of chemical composition methane production was determined due to different methods. Methods allow, with high accuracy, to calculate the yield of methane from silage from whole maize plant used as a mono-substrate for biogas. Estimation of methane production from the gross energy gives inflated results. For practice the most useful is to estimate the yield of methane from the dry weight content, due to the ease of determination.
