    This study was carried out to determine the forage production potentials of different sweet sorghum genotypes under Mediterranean-type climate conditions as the second crop in 2020. Three different sweet sorghum genotypes (Erdurmuş, Uzun varieties, and M81-E line) and four nitrogen doses (0.0, 7.5 12.5, 17.5 kg da-1) were used in this research. The experimental design was a randomized complete block with three replications. Some parameters such as plant height, stem diameter, plant number per m2, leaf number, leaf and stem ratio, forage yield, and dry matter yield of sweet sorghum genotiyps were investigated in the experiment. According to the results, M81-E gave the highest values in terms of stem diameter, leaf number, forage yield, and dry matter yield parameter compared to other genotypes. Forage yield values of the genotypes were between 2969.9 and 5815.0 kg da-1 and dry matter yield values were 1105.7 and 2837.8 kg da-1. Forage yield values vary between 2920.1 and 4674.6 kg da-1 for the nitrogen doses. The highest forage yield was obtained at 12.5 and 17.5 kg da-1 nitrogen doses, which were in the same statistical group. Fertilization can be made with a 12.5 kg da-1 nitrogen dose in sweet sorghum due to the negative environmental effects of chemical fertilizers.
