The objective of the study was determination of usefulness of three sorghum varieties (Sucrosorgo 506, Santos, Rona 1) cultivated as primary and secondary crops for the production of bioethanol. Field experiments were carried out in 2013-2015 at the Experimental Farm in Sielec Stary, located in a region with low annual precipitation (below 550 mm) and with low levels of ground water. The yields of the sorghum varieties obtained after cultivation as a primary and secondary crop were compared. Also, the amounts of bioethanol produced from those varieties were evaluated. The results allowed for recommendation of ‘Sucrosorgo 506’ variety for cultivation for biomass as primary and secondary crops, and for production of cellulosic ethanol from its biomass. It was found that ‘Rona 1’ and ‘Sucrosorgo 506’ varieties showed higher ethanol values as the primary and secondary crops than ‘Santos’. Moreover, cultivation of sorghum as a secondary crop with rye as a winter catch crop resulted in higher biomass yields than those obtained from sorghum cultivated as a primary crop. This allows for reducing the costs of obtaining sorghum biomass for bioethanol production.

The aim of the described analysis is characteristic of big bluestem as an energy crop. This is prairie grass with C4 type of photosynthesis, which is not popular species in Poland. The article is a review and the aim of this study on Andropogon gerardi was to show the possibilities of its usefulness as a biomass for bioenergy production in the Polish environmental conditions based on references reports. Slow growth rate after the winter and the ease of weeding of the plantation makes Andropogon gerardi a low-cost energy crop in polish conditions. In addition, the cost of plantation establishment in comparison with the shrubby willow was determined in order to check the profitability of its cultivation in Poland.
