<abstract xmlns="http://www.w3.org/1999/xhtml"> The experiments aimed at the comparison of the growth and production parameters of sorghum with other field crops were established in the experimental workplaces CVRV-VÚA in Milhostov. In the course of favourable meteorological factors, the slowest initial development of vegetation height and dynamics of biomass accretion was observed in sorghum. From 15th August, however, sorghum accretion intensity significantly exceeded all the monitored field crops. The total cost of the cultivation of sorghum for silage accounted for 870.34 € ha-1 and of maize for silage 861.36 € ha-1. The difference resulted from different levels of material costs. In the experiment, the harvested amount reached 62.70 t ha-1 for sorghum silage and 54.20 t ha-1 for maize (33% moisture). At these yield and silage costs 33 € t-1, sorghum achieved a profit of 1198.76 € ha-1 without subsidy, while maize achieved a profit of 927.24 € ha-1. The yields exceeding 26.37 t ha-1 for sorghum and 26.10 t ha-1 for maize would be sufficient to achieve profits.</abstract>
