This study was carried out during the second crop season of 2008-2009 under irrigated conditions at Anatolian Agricultural Research Institute in to determine the yield and yield components of sorghum varieties (Leoti, Early Sumac and Rox) sudangrass variety (Gözde 80), sorghum- sudangrass hybrid varieties (Sweet sioux-5 and Super--610, Pioneer-
3396,Tüm-82, Ant-90 and TTM815) varieties as second crop used after Hungarian vetch variety Budak in the experiment. Both main crop and second crop trials were set up as four replications by trial pattern of randomized complete block design. Main cropHungarian vetch (Vicia pannonica) was harvested at the period of 50 flowering. After harvesting main crop, second crops were seeded and second crops were harvested at the period of starch. As a result of the study, A growing season, main and second product was found to be raised at the two products for difference among varieties by the year of growth. According to the two years averages herbage yield varied from 7772 kg ha-1 to 4840 kg ha-1. The highest herbage yield was obtained from Pioneer Corn with 7772 kg ha-1. Relative feed value (RFV) of sorghum and maize varieties ranged from 93,12 to 125,17. Products obtained as a result of research can be classified as good values of RFV. Metabolisable energy of sorghum and maize varieties ranged from 2,09 to 2,293 Mcal kg-1 KM. Ant90 had the highest ME, but did not differ from Ttm815 and Pioneer 3396 Rox had lower ME content than all other cultivars while ME content in the remaining cultivars was similar. There was a strong negative relationship between acid detergent fiber and relative feed value and metabolisable energy content, while relative feed value and metabolisable energy were positively correlated. Despite difference of yield between these varieties, they cultivated as se ilar regions.
