In this study, sorghum-sudangrass hybrid 'Aneto' and legumes (soybean and cowpea) intercropping at different seed rates (100:100; 50:100, 100:50) were examined for hay yield, protein content, protein yield, relative feed value (RFV) and mineral content (P, K, Mg, Ca) in 2013 and 2014. As legume Yesilsoy (S-yes) and Yemsoy (S-yem) verieties of soybean and Ulkem (C) varietiy of cowpea were used. Sorghum-sudangrass hybrid x legume intercropping produced higher hay and protein yield compare to their monocrops. RFV of hay also exalted with intercropping copmpare to alone sorghum-sudangrass hybrid (S). Over the years, the highest hay yield was obtained from S intercropped with S-yes at 100:100 (21.61 t ha(-1)), 100:50 (20.68 t ha(-1)) seed rates and with C at 50:100 (20.40 t ha(-1)) seed rate. Protein yield was the highest in 100S:100S(yes) tratment in 2013 (2.16 t ha(-1)), 2014 (2.85 t ha(-1)) and combined years (250 t ha(-1)). However, S intercropping with C at 100:100, 50:100 (in 2013) and at 50:100 (in 2014) seed rates were at par with 100S:100S(yes). This study indicated that seed rate and species or variety selection extremly important in mixture cropping. Thus, generally sorghum-sudangrass hybrid and 'Yesilsoy' variety of soybean at 100:100 seed rate exhibited the best results in regarding hay and protein yield in the present conditions.
