Abstract :The objective of this study was to determine sorghum varieties that are suitable for north Anatolian conditions and possess high nutrient yields. Eight grain sorghum varieties, namely, Öğretmenoğlu, Akdarı, Aldarı, Beydarı, Ramada, A-298, DK-64 and KS-397, were utilized as plant material in the experiment. When the grains were mature, they were harvested first, and then residues were harvested by hand. Samples were analyzed for dry matter insert ignore into journalissuearticles values(DM);, organic matter insert ignore into journalissuearticles values(OM);, crude protein insert ignore into journalissuearticles values(CP);, neutral detergent fiber insert ignore into journalissuearticles values(NDF);, acid detergent fiber insert ignore into journalissuearticles values(ADF);, and in vitro DM digestibility. Digestible DM yields were also calculated. The DM content of residues ranged from 26.64% to 35.36% insert ignore into journalissuearticles values(P < 0.05);. Concentrations of OM in residues were significantly lower insert ignore into journalissuearticles values(P < 0.05); in Ramada and Aldarı compared with the other varieties. While NDF and ADF concentrations in residues were highest in Beydarı, they were lowest in DK-64 insert ignore into journalissuearticles values(P < 0.05);. Residues of DK-64 and Aldarı had the highest in vitro digestibilities, DM yields and digestible DM yields insert ignore into journalissuearticles values(P < 0.05);. Öğretmentoğlu grain had the highest CP, whereas Beydarı had the lowest in vitro digestibility insert ignore into journalissuearticles values(P < 0.05);. Ramada grain had the highest DM and digestible DM yields insert ignore into journalissuearticles values(P < 0.05);. Total insert ignore into journalissuearticles values(forage + grain); DM yield, digestible DM yield and CP yield were significantly higher in Ramada and A-298 compared with the other varieties insert ignore into journalissuearticles values(P < 0.05);. It can be concluded that, of the sorghum varieties grown, Ramada had the highest yield and adaptation for north Anatoilan conditions, followed by A-298, based on digestible DM and CP yields, respectively.
