This research has been carried out to determine the variations in certain agronomic features of sweet sorghum (Topper-76 and M81-E) and sorghum x sudangrass hybrid varieties (Nutrima and Nutri Honey) depending on different harvesting practices. This research was conducted in Research and Experimental Area of the Canakkale Onsekiz Mart University, Faculty of Agriculture located at Dardanos, Çanakkale Province in 2020. This study has been established according to randomized complete block design using 4 replications. In the experiment, main plots were consisted of sorghum varieties while the sub plots were formed as different harvesting heights (30, 60, 90, 120, 150 cm and physiological stage). In the study, plants were harvested on a height of 10 cm when they reached their specific harvesting maturity. Later, the plant height, fresh hay yield, dry hay yield, ratio of dry matter and ratio of leaf, stalk and panicle have been determined from the harvested plant samples. According to the results of this study, fresh hay yield, dry hay yield, ratio of dry matter, ratio of stalk and panicle were increased correlatedly with plant growth, but there was a decline in leaf ratio. The highest plant heights were recorded as 131.6 cm and 130.9 cm in Nutri Honey and M81-E varieties, while the highest fresh and dry hay yields were determined in M81-E variety of sweet sorghum. There was non-significant change between varieties in terms of leaf and stalk ratios, but the highest stalk ratio (8.73%) has been observed in Nutri Honey variety. In conclusion, in terms of the investigated characteristics, the Nutri Honey variety of sorghum x sudangrass and M81-E variety of sweet sorghum are recommended as summer roughage crops under similar ecological conditions.
