Quality Characteristics of Sorghum (Sorghum Bicolor (L.) Moench)and Sorghumxsudan Grass Hybrids (Sorghum Bicolor (L.) Moenchxsorghum Sudanense Stapf.) Cultivated as Second Crop After Barley in Ercis-Van Ecological Condition

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 sorghumxsudan grass hybrid cultivars as second crop after barley in Ercis-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 sorghumxsudangrass 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 Ercis-Van ecological conditions in terms of yield and quality, but 877-cultivar and Sweet Sioux sorghumxsudangrass hybrid cultivars can be suggested in terms of only yield.
