| Popis: | The aim of the study was to assess the greenhouse gases emissions in different maize cultivation systemsin monoculture compared to its cultivation in crop rotation systems. To assess the GHG emissions theBiograce 4 public calculator was used. Assessments were conducted for various maize cultivation systemsin the years 2013-2014 in the two IUNG experimental stations: RZD Grabów and SD Baborówko. Theresults showed that the values of GHG emissions in maize – taking into account allocation of emissionsto by-products – were determined mainly by the yield. In SD Baborówko the emission values ranged from14.2 to 19.5 g CO2 eq/kg/MJ of bioethanol, irrespectively of the cultivation system, and were lower thanthe standard value. In RZD Grabów only maize cultivated in monoculture in reduced tillage and maizecultivated in 2014 in ploughing system and crop rotation may be used for bioethanol production. |
