The experiment was conducted during winter of the season 2012-2013 in one of fields of (Mahaweel / Bada`a Kabeer) north city center of Babel , to investigate the response of Forage mass to dates of cutting and ratios of forage mixtures(barley+barseem), A factorial arrangement in randomized complete block design in split plot arrangement with three replication was used , In main plots was cutting dates : T1 (50 days after planting) , T2 (60 days after planting) and T3 (70 days after planting) , sub plots was forage mixtures ratios : D1(barley 1 : 1 clover) , D2(barley 1 : 2 clover) and D3(barley 1 : 3 clover) .
. the studied traits was : number of leaves /m2 , cover leaves (m2 / ha) , net asdsimilation rate (g/cm2/week) , leaves per stems (%) , green forage yield (tan/ha) , dry forage yield (tan/ha) , percentage of Protein (%) and protein yield (tan/ha) ; The treatment third date ( T3 ) was superior in number leaf /m2 , leaves cover, net asdsimilation rate , leaves per stems , green forage yield , dry matter yield , percentage of protein and protein yield . The treatment forage mixtures ratios (D2) was superior in net asdsimilation rate , green forage yield and dry mater yield while treatment (D3) was superior in No. leaf/m2 , leaves cover , percentage of protein and protein yield ; A linear relationship was found between cutting dates with forage mixtures ratios in yield traits was found in treatment (D3× T3) and (D2× T3) , So the treatment (D3× T3) was superior in number leaf/m2 , leaves cover , percentage of protein and protein yield ; The treatment (D2× T3) was superior in net asdsimilation rate , leaves per Stems , green forage yield , dry mater yield .
