Crop yields of biomass and its energetic efficiency depend mainly on the selection of annual plants cultivated in rotation under specific climate and soil conditions. The suggested five-field crop rotation is designed for arable farms, specializing in the production of biomass for renewable energy, operating on average quality soils (class IV) with limited precipitation (<550 mm). The results of the selection of plants for the suggested rotation, determined on the basis of field and production experiments conducted in 2007-2011 at the experimental farm Stary Sielec (district of Rawicz), confirmed the possibility of obtaining high yields of economically justified biomass from an area unit.
