Abstract: The aim of this study was to compare their grass qualities by determining hay yields, crude protein ratios and yields of some sorghum and sorghumοΏ½sudan grass hybrid cultivars as second crop after barley in Erci -Van ecological condition in 2003. The experimental data were analyzed using randomized complete block design with 3 replications. In the present study, sorghum cultivars (Rox) and 7 sorghumοΏ½sudangrass hybrid cultivars (Grazer, Seweet Sioux, GW-9110, Sugar Leaf, Grass-II, 877 and GOzde-80) were used. For all cultivars, average of hay yield ranged from 9770-20550 kg ha 1. It was found in the present study that, cultivars with the highest hay yield were 877-cultivar (20550 kg ha 1) and Seweet Sioux cultivar, cultivars having the highest crude protein ratio were determined as Sugar Leaf (11.0%), Grazer (10.8%) and Sweet Sioux (10.5%), respectively. Cultivars with highest crude protein yield were determined as Sweet sioux (2140 kg ha 1) and Grazer (1750 kg ha 1). As a result, Sweet sioux and Grazer cultivars can be recommend to farmers in Erci -Van ecological conditions in terms of yield and quality, but 877-cultivar and Sweet Sioux sorghumοΏ½sudangrass hybrid cultivars can be suggested in terms of only yield.
