In our paper we have dealt with the biomass-based energy production during the agricultural production, since the sustainable energy management is one of the most actual issues. In our research we wanted to know how much renewable energy could be produced on a field of 1800 hectares with five plants (silage maize, Lucerne, wheat, maize, sunflower). Data of the energy content were collected from literature, all other data were collected from a company in the Northern Great Plain Region with 1800 hectares and the information from the Institute of Agricultural Engineering (IAE). Besides, we analysed how much income could be reached and for what the produced energy could be used, what demand it could meet by replacing fossil energy sources having high environmental pressure. Crop production technologies applied in the model were set up by the practical experiences of a real agricultural company. Working operations were set on a monthly basis with the assignment of prime mover machinery relations. The material needs of the working operations were also set (fertilizers, pesticides, sowings, twines, silage foil) where it was needed. To answer our research question two model variants were elaborated. In the first model variant the five crops were competed by the maximum energy content, and in the second variant by the maximum gross margin. Production optimization was done for 1800 hectares. We supposed that 100% of the plant products are marketed (animal farms are not considered), and in the model only raw material production is done (further processing of plant products for energy purposes are not part of this analysis). Besides, we supposed that these five plants will be used as: by-products (wheat straw, maize stem, sunflower stem) and Lucerne hay by direct combustion; bioethanol from wheat and maize grain; biodiesel from sunflower grain; biogas from silage maize.
