Abstract: The forage and seed yields of common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica Crantz.), hairy vetch (Vicia villosa Roth.), grasspea (Lathyrus sativus L.) and barley (Hordeum vulgare L.) grown as mixture were investigated in field experiments conducted at the Faculty of Agriculture, Gaziosmanpasa University, in 2001/02 and 2002/03. Field experiments, designed in a factorial randomized compelete block with three replications, were carried out during 2001-2002 and 2002-2003 starting in the second week of November, 2001 and 2002. The highest dry matter (14435.8 kg ha-1) and total seed yields (3274.3 kg ha-1) were obtained from the mixture including 34% barley and 66% grasspea line 455, while the highest green forage yield (43401.5 kg ha-1) was obtained from the mixture including 34% barley and 66% Efes-79. In addition, the highest barley ratio in dry matter (95.67%) was achieved with the 34% barley and 66% Urem-79 mixture. The mixture of 34% barley and 66% Menemen-79 produced the highest legume ratio in dry matter (7.86%). The mixtures out yielded the pure barley sowing with respect to green forage, dry matter and total seed yields.
