dc.descriptionSorghum is a cereal crop of major importance in global production. It is grown in hot and dry regions of the world. In Poland, this species has so far not been cultivated for grain due to unfavourable climatic conditions. Currently, climate warming and the extension of the growing season provide an opportunity to introduce sorghum into grain cultivation. Three grain sorghum cultivars Albanus, Anggy, GK Emese were used in the ongoing microplot trials and three different nitrogen rates were applied: 80, 100 and 120 kg ha-1. The research was conducted over two growing seasons. The aim of the study was to determine the effect of cultivar and level of nitrogen fertilisation on the yield, yield structure and grain protein content of sorghum. A differentiated response of cultivars to nitrogen fertilisation was shown. Alba- nus and Anggy cultivars have similar yield potential and reaction to nitrogen fertilisation, and the optimum nitrogen dose for the cultivars is 100 kg of nitrogen per hectare, and an increased dose does not significantly increase the yield. Regardless of the level of nitrogen fertilization, the GK Emese variety always showed a higher protein yield compared to the other tested sorghum vari- eties. The cultivar GK Emese showed the highest yield potential. In 2020 it exhibited the highest increase in grain and protein yield along to increase of nitrogen fertilisation.en-US
